I had something similar happen the first couple times I tried to make MacOSX
10.10, Anaconda, and graph-tool work together.
In my case it failed with Fatal Python error: PyThreadState_Get: no current and
then crashed the kernel, but as Tiago knows it's indeed probably a mismatch
between the compiler used for boost vs graph-tool.
I finally succeeded with homebrew by compiling everything from sources instead
of using bottles, thus insuring the same compiler (clang) had been used for
everything. Takes quite a while but it worked.
brew -v install --with-icu4c --build-from-source --with-c++11 boost
brew -v install --with-icu4c --build-from-source --with-c++11 boost-python
brew -v install --build-from-source graph-tool --without-scipy ...
--without-matplotlib --without-numpy
First time I installed boost without the --with-c++11 option and importing
graph-tool kept crashing in the same manner. Simply recompiling boost and
boost-python with it after everything else was already installed fixed it.
I haven't yet completely figured out how to cleanly install all components in
the anaconda directory, but I get away with it for now using
import site site.addsitedir('/usr/local/lib/python2.7/site-packages/') import
graph_tool.all as gt
at the beginning of projects using graph-tool. If you're using MacPorts I
suspect you won't have to do this, and also that the necessary compile options
should be similar that those for homebrew.
