Include libraries at /opt/local/lib on OSX?

[rafi]

Using OSX and Macports, how can I instruct the build to use /opt/local/lib and /opt/local/include? Tried adding INCLUDE_DIRECTORIES(/opt/local/lib /opt/local/include) in CMakeLists.txt, compilation reaches 82% but fails:

$ cmake . -DCMAKE_INSTALL_PREFIX=/opt/local
...
$ make
...

make[2]: *** [bin/libglyr.1.1.0.dylib] Error 1
make[1]: *** [lib/CMakeFiles/glyr.dir/all] Error 2
make: *** [all] Error 2```

I also receive this dev warning on cmake:

CMake Warning (dev):
  Policy CMP0042 is not set: MACOSX_RPATH is enabled by default.  Run "cmake
  --help-policy CMP0042" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  MACOSX_RPATH is not specified for the following targets:

   glyr

This warning is for project developers.  Use -Wno-dev to suppress it.

You probably want to set CMAKE_INSTALL_PREFIX: cmake . -DCMAKE_INSTALL_PREFIX=/opt/local.

See here for more details. Im not yet sure if that warning you get is relevant. Could be harmless too.

That's what I was trying with. When compiling sources without cmake I normally run make CFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib", but I'm not sure how to do it with cmake. I tried adding INCLUDE_DIRECTORIES(/opt/local/lib /opt/local/include) in CMakeLists.txt like I mentioned before, but still no luck, it fails at 82%..

[sahib]

I got you wrong then. You want to add custom cflags and ldflags. I understood initially you want to install the library into those directories.

You can try this:

cmake . -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_C_FLAGS= "-I/opt/local/include" -DCMAKE_EXE_LINKER_FLAGS="-L/opt/local/lib"

That's not really related to glyr though...

No luck either.. same error.

I was able to get passed the gthread-2.0 error on OS X using:

cmake . -DCMAKE_EXE_LINKER_FLAGS="-L/opt/local/lib" -DCMAKE_SHARED_LINKER_FLAGS="-L/opt/local/lib"
make
sudo make install

@RichieB2B thanks! Were you able to run it?

Yes, it seems to be working fine. Did you completely rebuild all object? Just start from scratch with a fresh git clone.

$ glyrc 
Usage: glyrc [GETTER] (options)

where [GETTER] must be one of:
 - cover

@RichieB2B thank you so much, it works.
