Build Question. #63

@lwille this project looks awesome and will definitely be a life saver!!! Thank you!!

I have run into this problem when trying to build or install this node package.

gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]
  CXX(target) Release/obj.target/gphoto2/src/autodetect.o
../src/autodetect.cc:3:10: fatal error: 'gphoto2/gphoto2-camera.h' file not found
#include <gphoto2/gphoto2-camera.h>

I am learning about node-gyp and have found a simple solution(hack) to get this project to build by replacing:

'link_settings': {
        'libraries': [
          '-lgphoto2',
          '-lgphoto2_port'
        ]
      },

with: 

'include_dirs': [
          '/usr/local/Cellar/libgphoto2/2.5.5/include/gphoto2/',
          '/usr/local/Cellar/libgphoto2/2.5.5/lib',
        ],
     'libraries': [
        '<!@(pkg-config libgphoto2 --libs)',
        '<!@(pkg-config libgphoto2_port --libs)',
      ],

So I am wondering what can I do to improve this project and get the build to work without my hack?

Here is the output of brew list libgphoto2:

$ brew list libgphoto2

Thanks for your help! :-)

It's definitely related to homebrew's include paths, but I can't see what's wrong in your case. Do you also have problems building other projects that depend on homebrewed libraries?

I don't have problems building other projects that depend on home-brew libraries, but I just decided to use gphoto2 exec instead, thanks for your help. :smile:
