Build CuraEngine from source instead of AppImage extraction#299
Merged
Conversation
The AppImage-extracted + patchelf'd binary doesn't seek back to update G-code header placeholders after slicing (TIME:6666, Filament used: 0m). Building from source with Conan 2 + CMake produces a clean binary that handles the header correctly without workarounds. Key changes to Dockerfile.cura-base: - Stage 1: Build CuraEngine from source (Conan 2 + CMake, GCC 13) with Arcus and plugins disabled (not needed for headless CLI) - Stage 2: Still extract printer definitions from AppImage (JSON only) - Stage 3: Minimal runtime with binary + collected shared libs Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Dockerfile.cura-baseto build CuraEngine from source using Conan 2 + CMake instead of extracting from the Cura AppImageDetails
The old approach extracted the CuraEngine binary from the ~300MB Cura AppImage, then used patchelf to fix the ELF interpreter and manually copied bundled shared libraries. This worked for slicing but the binary couldn't seek back to the G-code file to update header placeholders with real values after slicing.
The new approach:
Image size: ~135MB. Build time: ~11 min (mostly Conan deps + CuraEngine compilation).
