Add include dir for node gyp

I am deploying a node-js app to heroku that requires the npm package imagemagic-native.

I made the buildpack install libmagick++-dev and export the include path:

export INCLUDE_PATH="$BUILD_DIR/.apt/usr/include:$INCLUDE_PATH"
export CPATH="$INCLUDE_PATH"
export CPPPATH="$INCLUDE_PATH"

Upon installing the imagemagic-native package with npm install, node-gyp is invoked to compile it's binaries. However I get this error:

remote:        > [email protected] install /tmp/build_720834c3a32b65d69ae603d7c618e20f/node_modules/imagemagick-native
remote:        > node-gyp rebuild
remote:        
remote:        make: Entering directory `/tmp/build_720834c3a32b65d69ae603d7c618e20f/node_modules/imagemagick-native/build'
remote:          CXX(target) Release/obj.target/imagemagick/src/imagemagick.o
remote:        In file included from ../src/imagemagick.cc:9:
remote:        ../src/imagemagick.h:1:22: warning: Magick++.h: No such file or directory

This suggests that gcc doesn't see the header files for libmagick++, because $CCPATH is not available to it.

How can I make npm install add the path to the list of include_dirs that node-gyp uses?

More detail about my use case is here: Using Magick++ in a node.js application on heroku

You can now do OTHER_CFLAGS='-I/usr/local/include' supposedly. See https://github.com/nickdesaulniers/node-nanomsg/pull/144

You can also use the "include_dirs" option in your project binding.gyp file. Read more about available options on the format description page.

I've spent some time trying to answer the same question. In the end, i've found the proper way to do this here. You need to set 'include_dirs' property in ~/.node-gyp/x.x.x/common.gypi. This is how I've set the include dir on Mac OS to /opt/local/include/ (which is where all macports intalls go):

...
['OS=="mac"', {
  'defines': ['_DARWIN_USE_64_BIT_INODE=1'],
  'include_dirs': ['/opt/local/include'],
  'xcode_settings': {
    'ALWAYS_SEARCH_USER_PATHS': 'NO',
...

Though I'm not sure it's applicable for heroku environment.

Try:

setting the environment variable CXX=/path/to/g++ -Ipath/to/include

and then restarting the process. If you're using bash this is done by

export CXX="/path/to/g++ -Ipath/to/include"

/path/to/include being where the missing header Magick++.h is located

if that doesn't work you may manually have to set CXX to include the -I in the makefile at /tmp/build_720834c3a32b65d69ae603d7c618e20f/node_modules/imagemagick-native/build then cding into that directory and calling make.
