Only use the source tarball if you need to customize the build (e.g., disable all coders except PNG/JPEG) or if your OS has no prebuilt package. 9. Common Pitfalls & Errors 9.1 Missing delegate libraries Symptom: configure succeeds but convert fails with no decode delegate for this image format . Solution: Install libpng-dev , libjpeg-dev , etc. before running configure . 9.2 Parallel make issues Symptom: Intermittent build failures with make -j .
