6# Common Solana Development Errors & Solutions
7 
8## GLIBC Errors
9 
10### `GLIBC_2.39 not found` / `GLIBC_2.38 not found`
11```
12anchor: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by anchor)
13```
14 
15**Cause:** Anchor 0.31+ binaries are built on newer Linux and require GLIBC ≥2.38. Anchor 0.32+ requires ≥2.39.
16 
17**Solutions (pick one):**
181. **Upgrade OS** (best): Ubuntu 24.04+ has GLIBC 2.39
192. **Build from source:**
20   ```bash
21   # For Anchor 0.31.x:
22   cargo install --git https://github.com/solana-foundation/anchor --tag v0.31.1 anchor-cli
23   
24   # For Anchor 0.32.x:
25   cargo install --git https://github.com/solana-foundation/anchor --tag v0.32.1 anchor-cli
26   ```
273. **Use Docker:**
28   ```bash
29   docker run -v $(pwd):/workspace -w /workspace solanafoundation/anchor:0.31.1 anchor build
30   ```
314. **Use AVM with source build:**
32   ```bash
33   avm install 0.31.1 --from-source
34   ```
35

38## Rust / Cargo Errors
39 
40### `anchor-cli` fails to install with Rust 1.80 (`time` crate issue)
41```
42error[E0635]: unknown feature `proc_macro_span_shrink`
43 --> .cargo/registry/src/.../time-macros-0.2.16/src/lib.rs
44```
45 
46**Cause:** Anchor 0.30.x uses a `time` crate version incompatible with Rust ≥1.80 ([anchor#3143](https://github.com/coral-xyz/anchor/pull/3143)).
47 
48**Solutions:**
491. **Use AVM** — it auto-selects `rustc 1.79.0` for Anchor < 0.31 ([anchor#3315](https://github.com/coral-xyz/anchor/pull/3315))
502. **Pin Rust version:**
51   ```bash
52   rustup install 1.79.0
53   rustup default 1.79.0
54   cargo install --git https://github.com/coral-xyz/anchor --tag v0.30.1 anchor-cli --locked
55   ```
563. **Upgrade to Anchor 0.31+** which fixes this issue
57 
58### `unexpected_cfgs` warnings flooding build output
59```
60warning: unexpected `cfg` condition name: `feature`
61```
62 
63**Cause:** Newer Rust versions (1.80+) are stricter about `cfg` conditions.
64 
65**Solution:** Add to your program's `Cargo.toml`:
66```toml
67[lints.rust]
68unexpected_cfgs = { level = "allow" }
69```
70Or upgrade to Anchor 0.31+ which handles this.
71 
72### `error[E0603]: module inner is private`
73**Cause:** Version mismatch between `anchor-lang` crate and Anchor CLI.
74 
75**Solution:** Ensure `anchor-lang` in Cargo.toml matches your `anchor --version`.
76 
77---
78 
79## Build Errors
80 
81### `cargo build-sbf` not found
82```
83error: no such command: `build-sbf`
84```
85 
86**Cause:** Solana CLI not installed, or PATH not set.
87 
88**Solutions:**
891. Install Solana CLI: `sh -c "$(curl -sSfL https://release.anza.xyz/stable/install)"`
902. Add to PATH: `export PATH="$HOME/.local/share/solana/install/active_release/bin:$PATH"`
913. Verify: `solana --version`
92 
93### `cargo build-bpf` is deprecated
94```
95Warning: cargo-build-bpf is deprecated. Use cargo-build-sbf instead.
96```
97 
98**Cause:** As of Anchor 0.30.0, `cargo build-sbf` is the default. BPF target is deprecated in favor of SBF.
99 
100**Solution:** This is just a warning if you're using older tooling. Anchor 0.30+ handles this automatically. If calling manually, use `cargo build-sbf`.
101 
102### Platform tools download failure
103```
104Error: Failed to download platform-tools
105```
106or
107```
108error: could not compile `solana-program`
109```
110 
111**Solutions:**
1121. **Clear cache and retry:**
113   ```bash
114   rm -rf ~/.cache/solana/
115   cargo build-sbf
116   ```
1172. **Manual platform tools install:**
118   ```bash
119   # Check which version you need
120   solana --version
121   # Download manually from:
122   # https://github.com/anza-xyz/platform-tools/releases
123   ```
1243. **Check disk space** (see "No space left" error below)
125 
126### `anchor build` IDL generation fails
127```
128Error: IDL build failed
129```
130or
131```
132BPF SDK: /home/user/.local/share/solana/install/releases/2.1.7/solana-release/bin/sdk/sbf
133Error: Function _ZN5anchor...
134```
135 
136**Solutions:**
1371. **Ensure `idl-build` feature is enabled (required since 0.30.0):**
138   ```toml
139   [features]
140   default = []
141   idl-build = ["anchor-lang/idl-build", "anchor-spl/idl-build"]
142   ```
1432. **Set ANCHOR_LOG for debugging:**
144   ```bash
145   ANCHOR_LOG=1 anchor build
146   ```
1473. **Skip IDL generation:**
148   ```bash
149   anchor build --no-idl
150   ```
1514. **Check for nightly Rust interference:**
152   ```bash
153   # IDL generation uses proc-macro2 which may need nightly features
154   # Override with stable:
155   RUSTUP_TOOLCHAIN=stable anchor build
156   ```
157 
158### `anchor build` error with `proc_macro2` / `local_file` method not found
159```
160error[E0599]: no method named `local_file` found for struct `proc_macro2::Span`
161```
162 
163**Cause:** proc-macro2 API change in newer nightly Rust.
164 
165**Solutions:**
1661. Upgrade to Anchor 0.31.1+ (fixed in [#3663](https://github.com/solana-foundation/anchor/pull/3663))
1672. Use stable Rust: `RUSTUP_TOOLCHAIN=stable anchor build`
1683. Pin proc-macro2: `cargo update -p proc-macro2 --precise 1.0.86`
169

171 
172## Installation Errors
173 
174### `No space left on device` during Solana install
175```
176error: No space left on device (os error 28)
177```
178 
179**Cause:** Solana CLI + platform tools can use 2-5 GB. Multiple versions compound this.
180 
181**Solutions:**
1821. **Clean old versions:**
183   ```bash
184   # List installed versions
185   ls ~/.local/share/solana/install/releases/
186   
187   # Remove old ones (keep only what you need)
188   rm -rf ~/.local/share/solana/install/releases/1.16.*
189   rm -rf ~/.local/share/solana/install/releases/1.17.*
190   
191   # Also clean cache
192   rm -rf ~/.cache/solana/
193   ```
1942. **Clean Cargo/Rust caches:**
195   ```bash
196   cargo cache --autoclean  # if cargo-cache is installed
197   # or manually:
198   rm -rf ~/.cargo/registry/cache/
199   rm -rf target/
200   ```
2013. **Clean AVM:**
202   ```bash
203   ls ~/.avm/bin/
204   # Remove unused anchor versions
205   ```
206 
207### `agave-install` not found
208```
209error: agave-install: command not found
210```
211 
212**Cause:** Anchor CLI 0.31+ migrates to `agave-install` for Solana versions ≥1.18.19.
213 
214**Solution:** Install via the Solana install script (which installs both):
215```bash
216sh -c "$(curl -sSfL https://release.anza.xyz/stable/install)"
217```
218 
219---
220 
221## Testing Errors
222 
223### `solana-test-validator` crashes or hangs
224```
225Error: failed to start validator
226```
227 
228**Solutions:**
2291. **Kill existing validators:**
230   ```bash
231   pkill -f solana-test-validator
232   # or
233   solana-test-validator --kill
234   ```
2352. **Clean ledger:**
236   ```bash
237   rm -rf test-ledger/
238   ```
2393. **Check port availability:**
240   ```bash
241   lsof -i :8899  # RPC port
242   lsof -i :8900  # Websocket port
243   ```
2444. **Consider Surfpool** as a modern alternative to `solana-test-validator`:
245   ```bash
246   curl --proto '=https' --tlsv1.2 -LsSf https://github.com/txtx/surfpool/releases/latest/download/surfpool-installer.sh | sh
247   ```
248 
249### Anchor test fails with `Connection refused` / IPv6 issue
250```
251Error: connect ECONNREFUSED ::1:8899
252```
253 
254**Cause:** Node.js 17+ resolves `localhost` to IPv6 `::1` by default, but `solana-test-validator` binds to `127.0.0.1`.
255 
256**Solutions:**
2571. **Use Anchor 0.30+** which defaults to `127.0.0.1` instead of `localhost`
2582. **Set NODE_OPTIONS:**
259   ```bash
260   NODE_OPTIONS="--dns-result-order=ipv4first" anchor test
261   ```
2623. **Edit Anchor.toml:**
263   ```toml
264   [provider]
265   cluster = "http://127.0.0.1:8899"
266   ```

270## Anchor Version Migration Issues
271 
272### Anchor 0.29 → 0.30 Migration Errors
273 
274**`accounts` method type errors in TypeScript:**
275```
276Argument of type '{ ... }' is not assignable to parameter of type 'ResolvedAccounts<...>'
277```
278 
279**Solution:** Change `.accounts({...})` to `.accountsPartial({...})` or remove auto-resolved accounts from the call.
280 
281**Missing `idl-build` feature:**
282```
283Error: `idl-build` feature is missing
284```
285 
286**Solution:** Add to each program's Cargo.toml:
287```toml
288[features]
289idl-build = ["anchor-lang/idl-build"]
290```
291 
292**`overflow-checks` not specified:**
293```
294Error: overflow-checks must be specified in workspace Cargo.toml
295```
296 
297**Solution:** Add to workspace `Cargo.toml`:
298```toml
299[profile.release]
300overflow-checks = true
301```
302 
303### Anchor 0.30 → 0.31 Migration Errors
304 
305**Solana v1 → v2 crate conflicts:**
306```
307error[E0308]: mismatched types
308expected `solana_program::pubkey::Pubkey`
309found `solana_sdk::pubkey::Pubkey`
310```
311 
312**Solution:** Remove direct `solana-program` and `solana-sdk` dependencies. Use them through `anchor-lang`:
313```rust
314use anchor_lang::prelude::*;
315// NOT: use solana_program::pubkey::Pubkey;
316```
317 
318**`Discriminator` trait changes:**
319```
320error[E0277]: the trait bound `MyAccount: Discriminator` is not satisfied
321```
322 
323**Solution:** Ensure you derive `#[account]` on your structs. The discriminator is now dynamically sized.
324 
325### Anchor 0.31 → 0.32 Migration Errors
326 
327**`solana-program` dependency warning becomes error:**
328Anchor 0.32 fully removes `solana-program` as a dependency. If your code imports from `solana_program::*`, change to the smaller crates:
329```rust
330// Before (0.31):
331use solana_program::pubkey::Pubkey;
332 
333// After (0.32):
334use solana_pubkey::Pubkey;
335// Or use anchor's re-export:
336use anchor_lang::prelude::*;
337```
338 
339**Duplicate mutable accounts error:**
340```
341Error: Duplicate mutable account
342```
343Anchor 0.32+ disallows duplicate mutable accounts by default. Use the `dup` constraint:
344```rust
345#[derive(Accounts)]
346pub struct MyInstruction<'info> {
347    #[account(mut)]
348    pub account_a: Account<'info, MyAccount>,
349    #[account(mut, dup = account_a)]
350    pub account_b: Account<'info, MyAccount>,
351}
352```
353

355 
356## Miscellaneous Errors
357 
358### `solana airdrop` fails
359```
360Error: airdrop request failed
361```
362 
363**Cause:** Rate limiting on devnet/testnet.
364 
365**Solutions:**
3661. Wait and retry
3672. Use the web faucet: https://faucet.solana.com
3683. For testing, use localnet where airdrops are unlimited
369 
370### Anchor IDL account authority mismatch
371```
372Error: Authority did not sign
373```
374 
375**Solution:** The IDL authority is the program's upgrade authority. Check with:
376```bash
377solana program show <PROGRAM_ID>
378```
379 
380### `declare_program!` not finding IDL file
381```
382Error: file not found: idls/my_program.json
383```
384 
385**Solution:** Place the IDL JSON in the `idls/` directory at the workspace root. The filename must match the program name (snake_case):
386```
387workspace/
388├── idls/
389│   └── my_program.json
390├── programs/
391│   └── my_program/
392└── Anchor.toml
393```

396 
397## LiteSVM Errors
398 
399### `undefined symbol: __isoc23_strtol` (litesvm native binary)
400```
401Error: Cannot find native binding.
402cause: litesvm.linux-x64-gnu.node: undefined symbol: __isoc23_strtol
403```
404 
405**Root cause:** LiteSVM 0.5.0 native binary is compiled against GLIBC 2.38+. The `__isoc23_strtol` symbol was introduced in GLIBC 2.38 (C23 standard functions). Systems with GLIBC < 2.38 (Ubuntu 22.04, Debian 12, etc.) cannot load this binary.
406 
407**Verified on:** Debian 12 (GLIBC 2.36) — Jan 2026
408 
409**Solutions:**
4101. **Upgrade OS** to Ubuntu 24.04+ or Debian 13+ (recommended)
4112. **Use Docker:**
412   ```dockerfile
413   FROM ubuntu:24.04
414   RUN apt-get update && apt-get install -y nodejs npm
415   ```
4163. **Fall back to `solana-bankrun`** if you can't upgrade:
417   ```bash
418   pnpm remove litesvm anchor-litesvm
419   pnpm add -D solana-bankrun anchor-bankrun
420   ```
4214. **Try litesvm 0.3.x** which may work on older GLIBC versions
422 
423### `Cannot find module './litesvm.linux-x64-gnu.node'`
424```
425Error: Cannot find module './litesvm.linux-x64-gnu.node'
426```
427 
428**Root cause:** pnpm hoisting doesn't always correctly link native optional dependencies for native Node addons.
429 
430**Solutions:**
4311. Delete `node_modules` and reinstall: `rm -rf node_modules && pnpm install`
4322. Use `node-linker=hoisted` in `.npmrc`:
433   ```
434   node-linker=hoisted
435   ```
4363. Install the platform-specific package explicitly:
437   ```bash
438   pnpm add -D litesvm-linux-x64-gnu
439   ```
440

442 
443## Platform Tools Errors
444 
445### `The Solana toolchain is corrupted` after fresh install
446```
447[ERROR cargo_build_sbf] The Solana toolchain is corrupted. Please, run cargo-build-sbf with the --force-tools-install argument to fix it.
448```
449 
450**Root cause:** Solana CLI 2.2.x downloads platform-tools v1.48 (~516MB compressed, ~2GB extracted). On systems with limited root partition space (<3GB free in `~/.cache/solana/`), extraction can fail silently, leaving a corrupted toolchain (e.g., `rust/` directory missing `rustc` binary).
451 
452**Verified on:** Debian 12, Solana CLI 2.2.16, root partition 9.7GB with 2.1GB free — Jan 2026
453 
454**Solutions:**
4551. **Run with `--force-tools-install`:**
456   ```bash
457   cargo build-sbf --force-tools-install
458   ```
459   This re-downloads and re-extracts. Takes 5-10 minutes on average connections.
460 
4612. **Ensure sufficient disk space** (~3GB free needed on partition containing `~/.cache/solana/`):
462   ```bash
463   df -h ~/.cache/solana/
464   # If too small, symlink to bigger disk:
465   rm -rf ~/.cache/solana/v1.48/platform-tools
466   mkdir -p /mnt/data/solana-cache/v1.48/platform-tools
467   ln -sf /mnt/data/solana-cache/v1.48/platform-tools ~/.cache/solana/v1.48/platform-tools
468   ```
469 
4703. **Manual extraction** (if `--force-tools-install` keeps cycling):
471   ```bash
472   # Download manually
473   wget https://github.com/anza-xyz/platform-tools/releases/download/v1.48/platform-tools-linux-x86_64.tar.bz2
474   # Extract to a disk with space
475   mkdir -p /mnt/data/solana-platform-tools/v1.48
476   cd /mnt/data/solana-platform-tools/v1.48
477   tar xjf /path/to/platform-tools-linux-x86_64.tar.bz2
478   # Symlink
479   ln -sf /mnt/data/solana-platform-tools/v1.48 ~/.cache/solana/v1.48/platform-tools
480   ```
481 
482**Note:** The `version.md` file is the last file extracted. Its presence confirms successful extraction.
483 
484### Anchor CLI version mismatch warnings (non-fatal)
485```
486WARNING: `anchor-lang` version(0.32.1) and the current CLI version(0.30.1) don't match.
487WARNING: `@coral-xyz/anchor` version(^0.32.1) and the current CLI version(0.30.1) don't match.
488```
489 
490**Root cause:** Using Anchor CLI 0.30.1 with `anchor-lang = "0.32.1"` in Cargo.toml. The build **succeeds** but prints warnings.
491 
492**Verified on:** Debian 12, Anchor CLI 0.30.1 building anchor-lang 0.32.1 — builds and generates IDL correctly — Jan 2026
493 
494**Impact:** Builds work. IDL generation works. But subtle runtime issues may occur with IDL format differences between 0.30 and 0.32.
495 
496**Solutions:**
4971. **Match versions** (recommended):
498   ```toml
499   # Anchor.toml
500   [toolchain]
501   anchor_version = "0.32.1"
502   ```
503   Then install matching CLI: `avm install 0.32.1`
5042. **Or downgrade crate:** Change `anchor-lang = "0.30.1"` in Cargo.toml
5053. **Ignore if just building:** The mismatch is cosmetic for `anchor build` and `anchor idl build`

509## edition2024 Crate Incompatibility (Cargo 1.84.0)
510 
511### `feature edition2024 is required` during `cargo build-sbf`
512```
513error: failed to download `constant_time_eq v0.4.2`
514 
515Caused by:
516  failed to parse manifest at `.../constant_time_eq-0.4.2/Cargo.toml`
517 
518Caused by:
519  feature `edition2024` is required
520 
521  The package requires the Cargo feature called `edition2024`, but that feature is not
522  stabilized in this version of Cargo (1.84.0 (12fe57a9d 2025-04-07)).
523```
524 
525**Root cause:** Platform-tools v1.48 (used by Solana CLI 2.2.16 and CI with Solana stable 3.0.14) bundles `cargo 1.84.0` (Solana Rust fork), which does **not** support `edition = "2024"`. Multiple crates in the Solana dependency tree have released versions requiring edition2024.
526 
527### ⚠️ Known edition2024 Crates (Updated Jan 31, 2026)
528 
529| Crate | Breaking Version | Safe Version | Pulled By |
530|---|---|---|---|
531| `blake3` | ≥1.8.3 | **1.8.2** | `solana-blake3-hasher` → `solana-program` |
532| `constant_time_eq` | ≥0.4.2 | **0.3.1** | `blake3` |
533| `base64ct` | ≥1.8.3 | **1.7.3** | `pkcs8`, `spki` → various crypto crates |
534| `indexmap` | ≥2.13.0 | **2.11.4** | `toml_edit` → `proc-macro-crate` → `borsh-derive` → `anchor-lang` |
535 
536**New crates may ship edition2024 at any time.** If you see this error with a crate not listed above, pin it to the previous version.
537 
538**Why existing repos break:** Projects without a `Cargo.lock` (or with a stale one) resolve to the latest crate versions at build time, pulling in edition2024-requiring releases. This is especially common in CI environments.

544### Solutions
545 
546**1. Pin all known problematic crates (recommended for CI):**
547```bash
548cargo generate-lockfile
549cargo update -p blake3 --precise 1.8.2
550cargo update -p constant_time_eq --precise 0.3.1
551cargo update -p base64ct --precise 1.7.3
552cargo update -p indexmap --precise 2.11.4
553```
554 
555**2. Pin via workspace Cargo.toml:**
556```toml
557# In workspace Cargo.toml
558[workspace.dependencies]
559blake3 = "=1.8.2"
560base64ct = "=1.7.3"
561```
562 
563**3. Always commit Cargo.lock for programs and Anchor projects:**
564```bash
565# Force-add if .gitignore excludes it
566git add -f Cargo.lock
567```
568This is the single most effective prevention — a committed lockfile prevents cargo from resolving to newer breaking versions.
569 
570**4. For monorepos with per-project Cargo.lock files (e.g., program-examples):**
571Each Anchor project that has its own `Cargo.toml` outside the workspace needs its own `Cargo.lock`. Generate and pin for each:
572```bash
573for dir in $(find . -path "*/anchor/Cargo.toml" -exec dirname {} \;); do
574  cd "$dir"
575  cargo generate-lockfile
576  cargo update -p blake3 --precise 1.8.2 2>/dev/null
577  cargo update -p constant_time_eq --precise 0.3.1 2>/dev/null
578  cargo update -p base64ct --precise 1.7.3 2>/dev/null
579  cargo update -p indexmap --precise 2.11.4 2>/dev/null
580  cd -
581done
582git add -f **/Cargo.lock
583```
584 
585**5. Wait for platform-tools update** — a future platform-tools version will ship a cargo that supports edition2024. Track at [anza-xyz/platform-tools](https://github.com/anza-xyz/platform-tools/releases).

587### `Could not find specification for target "sbpf-solana-solana"` with `--tools-version`
588```
589error: Error loading target specification: Could not find specification for target "sbpf-solana-solana".
590Run `rustc --print target-list` for a list of built-in targets
591```
592 
593**Root cause:** Using `cargo build-sbf --tools-version v1.43` with Solana CLI 2.2.16. The CLI generates `--target sbpf-solana-solana` but platform-tools v1.43 only knows older target triples (e.g., `sbf-solana-solana`). The SBPF target rename happened between v1.43 and v1.48.

595**Verified on:** Debian 12, Solana CLI 2.2.16 — Jan 30, 2026
596 
597**Solution:** Don't downgrade platform-tools below your CLI's default version. Use the default tools version (v1.48 for CLI 2.2.16).

601## Verified Test Results (Debian 12, Jan 2026)
602 
603Environment: Rust 1.93, Solana CLI 2.2.16, Anchor CLI 0.30.1, Node 22.22.0, GLIBC 2.36
604 
605| Test | Command | Result | Notes |
606|------|---------|--------|-------|
607| Anchor CLI/crate mismatch | `anchor build` (CLI 0.30.1 / anchor-lang 0.32.1) | ⚠️ PASS with warnings | Builds succeed; prints version mismatch warnings |
608| cargo build-sbf (native) | `cargo build-sbf` on hello-solana, counter, transfer-sol, create-account, checking-accounts | ✅ PASS | All build after platform-tools v1.48 installed correctly |
609| solana-bankrun (GLIBC 2.36) | `npm install solana-bankrun && require('solana-bankrun')` | ✅ PASS | `start` function available, works on GLIBC 2.36 |
610| litesvm npm (GLIBC 2.36) | `npm install litesvm && require('litesvm')` | ❌ FAIL | `undefined symbol: __isoc23_strtol` — requires GLIBC ≥2.38 |
611| @solana/web3.js CJS | `require('@solana/web3.js')` | ✅ PASS | Keypair, Connection etc. available |
612| @solana/web3.js ESM | `import * as web3 from '@solana/web3.js'` | ✅ PASS | Full ESM support on Node 22 |
613| @solana/kit (web3.js v2) ESM | `import('@solana/kit')` | ✅ PASS | ESM-only, works on Node 22 |
614| @coral-xyz/anchor CJS | `require('@coral-xyz/anchor')` | ✅ PASS | Program, Provider etc. available |
615| @coral-xyz/anchor ESM | `import * as anchor from '@coral-xyz/anchor'` | ✅ PASS | Full ESM support on Node 22 |
616| IDL generation | `anchor idl build` (from program dir) | ✅ PASS | Generates valid JSON IDL with CLI 0.30.1 |
617| Cargo duplicate deps | `cargo tree -d` on program-examples | ⚠️ INFO | 2295 lines of duplicate deps (ahash, base64, borsh, curve25519-dalek, ed25519-dalek, etc.) — normal for Solana workspace |
618| Platform tools corruption | `cargo build-sbf` on fresh install | ❌ FAIL then PASS | Initial corruption due to disk space; fixed with `--force-tools-install` on adequate disk |

620### Key Findings
6211. **litesvm 0.5.0 npm is BROKEN on Debian 12** (GLIBC 2.36) — use `solana-bankrun` as fallback
6222. **solana-bankrun works perfectly** on GLIBC 2.36 — recommended for Debian 12
6233. **Platform-tools v1.48 needs ~2GB disk** for extraction — symlink `~/.cache/solana/` to a larger partition if root is small
6244. **Anchor CLI 0.30.1 successfully builds anchor-lang 0.32.1** — warnings only, no errors
6255. **Node 22 has full ESM+CJS support** for all Solana JS packages tested
6266. **Cargo duplicate dependencies are normal** in Solana monorepos (borsh 0.9/0.10/1.x, curve25519-dalek 3.x/4.x, etc.)
