Build log showing failure

[Schamschula (Marius Schamschula)]

CMakeLists.txt for gmic do not explicitly do anything other than cmake does by default. Currently gmic does support macOS version 10.9 and above.

[dbevans (David B. Evans)]

Replying to Schamschula:

CMakeLists.txt for gmic do not explicitly do anything other than cmake does by default. Currently gmic does support macOS version 10.9 and above.

Perhaps you made a misstatement here? Based on the recent rebuild results, it appears that gmic builds correctly with macOS 10.11+ including 10.15 (my local build). If you believe there is nothing to be done for the earlier platforms, perhaps you should mark those earlier versions as known failures early on in the build process.

[Schamschula (Marius Schamschula)]

I found the info for 10.9 and above in the CMakeLists.txt file in gmic-qt, which seems to be the component that is failing:

if (APPLE)
    add_definitions(-Dcimg_display=0)
    add_definitions(-D_IS_MACOS_)
    set(CMAKE_MACOSX_RPATH 1)
    set(BUILD_WITH_INSTALL_RPATH 1)
    add_definitions(-mmacosx-version-min=10.9 -Wno-macro-redefined -Wno-deprecated-register)
endif()

So I assume that the developers might have unintentionally broken something with a recent update.

[dbevans (David B. Evans)]

Ok, my misunderstanding. You said it right in the beginning. So it looks like the developers think it should build on 10.9+.

I believe this may be a qmake issue.
There is a ​pull request that attempts to solve the problem.
