Failed to build on OSX Mojave

[koreus7]

Fresh install of Mojave 10.14.6 Installed Xcode, developer tools and brew.

brew install opencv@2 --c++11 --without-python --without-numpy --without-test

Failed so I installed open cv without any flags.

Then I did

brew install cmake
brew install pkgconfig
brew install libffi
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
export LDFLAGS="-L/usr/local/opt/libffi/lib"
mkdir build
cd build
cmake .. -G Ninja
ninja

ninja: build stopped: subcommand failed.

If I remove the typedef from FreeImage.h then I get errors complaining that BOOL is not defined. Which is conflicting because according to ninja/cmake it is defined twice so removing one definition should still leave it defined.

[MatthewScholefield]

Hmm, looks like that problem is related to this issue from 10 years ago. Perhaps we could fix this by upgrading freeImage, but I'm not that sure.

[koreus7]

The fix in that issue seems to be replacing the typedef with a define

typedef int32_t BOOL;

Replaced by:

#define BOOL int32_t

In any case I suppose there is a version of free image which is compatible with the latest OSX.

[koreus7]

I just diffed the FreeImage header from the latest OF distribution (which compiles on my machine) and the one here.

I'm not sure what is being done here https://github.com/openframeworks/apothecary/blob/master/apothecary/formulas/FreeImage/FreeImage.sh to get this version of the header but the result is here http://ci.openframeworks.cc/libs/0.10.1/openFrameworksLibs_master_osx1.tar.bz2

[koreus7]

OF 10.1 is using a patched branch of FreeImage

GIT_URL=https://github.com/danoli3/FreeImage
GIT_TAG=3.17.0-header-changes

with the headers fixed for OSX

I tried to build against that version and got:

Undefined symbols for architecture x86_64:
  "InitJXR(Plugin*, int)", referenced from:
      _FreeImage_Initialise in Plugin.cpp.o

Seems similar (though possibly not related) this this issue: https://github.com/openframeworks/openFrameworks/issues/4385
