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: > imagemagick-native@1.7.0 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?
