"error: unable to create output directory" 351 | **Solution**: 352 | - Check file permissions in project directory 353 | - Ensure adequate disk space 354 | - Try cleaning build cache: \`rm -rf zig-cache zig-out\` 355 | 356 | ### 4. Cross-compilation linking errors 357 | **Solution**: 358 | - Install target system libraries if needed 359 | - Use \`-fno-sanitize=undefined\` for some targets 360 | - Check target triple is correct 361 | 362 | ### 5. "error: unable to parse build.zig" 363 | **Solution**: 364 | - Check Zig syntax in build.zig 365 | - Ensure all imports are valid 366 | - Use \`zig fmt build.zig\` to format and catch errors 367 | 368 | ### 6. Slow build times 369 | **Solutions**: 370 | - Use incremental compilation (default in newer Zig versions) 371 | - Reduce debug info in release builds 372 | - Use \`--cache-dir\` to specify cache location 373 | - Consider parallel builds with \`-j\` 374 | 375 | ### 7.
