MacOS arm64 shared build #89

Closed adamjw24 closed 2 years ago

adamjw24 commented 2 years ago

After compiling a shared build for arm64 under MacOS using default settings, the apps linking against libvvdec fail at start with SigKill (9).

For now, the cause of the issue is unknown, but somehow connected to Xcode. Building under MacOS without Xcode helps.

For make-based build, please use g=ninja or g=umake to select an alternative generator. For CMake, select 'Ninja' or 'Unix Makefiles' as the generator to bypass Xcode.

I just built the latest revision from master (e83c1166) on ARM64 Mac and the test suite completed successfully. I think we can close this issue.

I just noticed: the build output actually tells us what goes wrong during the install step:

-- Installing: /Users/hege/projects/vvdec/install/lib/libvvdec.dylib
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: warning: changes being made to the file will invalidate the code signature in: /Users/hege/projects/vvdec/install/lib/libvvdec.dylib
-- Installing: /Users/hege/projects/vvdec/install/bin/vvdecapp
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: warning: changes being made to the file will invalidate the code signature in: /Users/hege/projects/vvdec/install/bin/vvdecapp

This is most probably due to the RPATH being updated during the install step.
