Hi all, I successfully compiled grpah-tool in my Mavericks OSX using homebrew for the dependencies optional or not (i.e. expat, boost, cairo,...) the configuration was ./configure LDFLAGS="-L/usr/local/Cellar" PYTHON_EXTRA_LDFLAGS="-L/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/Python" CPPFLAGS="-I/usr/local/include/sparsehash" PYTHON_VERSION="2.7.6" --with-numpy=/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy --with-scipy=/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy --enable-cgal-valgrind --disable-cairo make and make install works fine here !! ---------------------------------------------------------------- No we I am coming into the problems... I need to be able also to draw my graphs, and so I need to install it again with cairo I had installed cairo, cairomm, py2cairo (for python2.7) before with homebrew, as you can see $ pkg-config cairomm-1.0 --libs -L/usr/local/Cellar/cairomm/1.10.0/lib -L/usr/local/Cellar/cairo/1.12.16/lib -L/usr/local/Cellar/libsigc++/2.3.1/lib -lcairomm-1.0 -lcairo -lsigc-2.0 $ pkg-config pycairo --libs -L/usr/local/Cellar/cairo/1.12.16/lib -lcairo $ pkg-config cairo --libs -L/usr/local/Cellar/cairo/1.12.16/lib -lcairo Now I am trying to configure the installation as: ./configure LDFLAGS="-L/usr/local/Cellar" PYTHON_EXTRA_LDFLAGS="-L/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/Python" CPPFLAGS="-I/usr/local/include/sparsehash" PYTHON_VERSION="2.7.6" CAIROMM_LIBS="-L/usr/local/Cellar/cairomm/1.10.0/lib -L/usr/local/Cellar/cairo/1.12.16/lib -L/usr/local/Cellar/libsigc++/2.3.1/lib" CAIROMM_CFLAGS="-O3 -lcairomm-1.0 -lcairo -lsigc-2.0" --with-numpy=/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy --with-scipy=/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy --enable-cgal-valgrind >> my_conf.log.txt and as you can see in the file my_conf.log.txt I take an error message: ....... checking pkg-config is at least version 0.9.0... yes checking for CAIROMM... yes checking python module: cairo... yes checking pycairo/pycairo.h usability... no checking pycairo/pycairo.h presence... no checking for pycairo/pycairo.h... no configure: error: pycairo headers not found The whole files my_conf.log.txt as well as the config.log are attached here. Does anyone have the same problem or know how to solve it? Thanks in advance, Nikos
