Qt5 Mac OSX Build Dolphin

by firodj, posted in Programming

NOT RECOMMENDED

For Qt5 Homebrew, use:

cmake -DQt5_DIR=$(brew --prefix qt5)/lib/cmake/Qt5 ..

If problem with zstd during compile discio, which usually because there is systemwide (brew) zstd installed, then force using vendored zstd by editing the top-level CMakeLists.txt to disable (commenting) these lines:

# pkg_check_modules(ZSTD QUIET libzstd>=1.4.0)

After that still facing the duplicate qt5 links.

RECOMMENDED

Qt5 was installed using Qt Online Installer for macOS.

Got error after successful build using CMake on Mac OSX High Sierra. The error message when running Dolphin:

qt.qpa.plugin: Could not load the Qt platform plugin "cocoa" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: cocoa.

After inspecting with otool the problem was the @rpath or
LC_RPATH which not set on the Dolphin executable (target dolphin-emu) which needed by libqcocoa.dylib.

otool -L Binaries/Dolphin.app/Contents/MacOS/platforms/libqcocoa.dylib

After fixing:


otool -l Binaries/Dolphin.app/Contents/MacOS/Dolphin  | grep LC_RPATH -A 4
          cmd LC_RPATH
