Hi, using either the latest git repo or 2.2.36 and running:
/usr/bin/python3.3 -c 'import graph_tool ; print(graph_tool.__version__)'
(or even python3.3 -c 'import graph_tool')
results in:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib64/python3.3/site-packages/graph_tool/__init__.py", line 101,

dl_import("from . import libgraph_tool_core as libcore")

exec(import_expr, local_dict, global_dict)

ImportError:

It appears that -lboost_python3_3-mt is not being used, even though my system
default is py3.3.
the interesting part of the ./configure log shows:
graph-tool will be installed at: /usr/lib64/python3.3/site-packages
===========================
Using python version: 3.3.5
===========================
checking for boostlib >= 1.53.0... yes
checking whether the Boost::Python library is available... yes
checking for exit in -lboost_python... no
checking for exit in -lboost_python... (cached) no
checking for exit in -lboost_python-2.7-mt... yes
if I recompile boost without py2.7 support (py3.3 only), then the interesting
part of the ./configure log shows:
graph-tool will be installed at: /usr/lib64/python3.3/site-packages
===========================
Using python version: 3.3.5
===========================
checking for boostlib >= 1.53.0... yes
checking whether the Boost::Python library is available... yes
checking for exit in -lboost_python... no
checking for exit in -lboost_python... (cached) no
checking for exit in -lboost_python-2.7... no
checking for exit in -lboost_python-3-mt... yes
and the test command works:
$/usr/bin/python3.3 -c 'import graph_tool ; print(graph_tool.__version__)'
2.2.36 (commit e3865108, Thu Jan 8 17:03:44 2015 +0100)
More detail on this issue is available in the gentoo bug tracker:
https://bugs.gentoo.org/show_bug.cgi?id=536734
How do we get the Makefile to have
BOOST_PYTHON_LIB = boost_python-3-mt
instead of
BOOST_PYTHON_LIB = boost_python-2.7-mt
when boost has been compiled for 2.7 and 3.3?
Thanks!
