I managed to compile graph-tool 2.2.5 and to solve linking problems with libcgal (thanks to tcb).
Could you please share what kind of problem you had with linking to cgal, and how you resolved it, so that I can incorporate the fix?
I believe it's a problem with cgal's build in macports. basically when i build graph_tool, the .so are linked to libCGAL with a relative path: tyler:~ hammer$ otool -L /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/libgraph_tool_topology.so /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/libgraph_tool_topology.so: /opt/local/Library/Frameworks/Python.framework/Versions/2.6/Python (compatibility version 2.6.0, current version 2.6.0) /opt/local/lib/libboost_iostreams-mt.dylib (compatibility version 0.0.0, current version 0.0.0) /opt/local/lib/libboost_python-mt.dylib (compatibility version 0.0.0, current version 0.0.0) /opt/local/lib/libboost_regex-mt.dylib (compatibility version 0.0.0, current version 0.0.0) /opt/local/lib/libexpat.1.dylib (compatibility version 7.0.0, current version 7.2.0) libCGAL.4.dylib (compatibility version 4.0.0, current version 4.0.0) /opt/local/lib/gcc44/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.13.0) /opt/local/lib/gcc44/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4) which is solved for every .so through install_name_tool (thanks to a suggestion by tcb): bash-3.2# install_name_tool -change libCGAL.4.dylib /opt/local/lib/libCGAL.4.dylib /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/libgraph_tool_topology.so etc. Do you have any suggestions?
When I try to import the graph_tool module i got this error:
In [1]: import graph_tool.all as gt ------------------------------------------------------------ File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/__init__.py", line 138 SyntaxError: Non-ASCII character '\xe2' in file /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/__init__.py on line 139, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details (__init__.py, line 138)
do you have any idea?
This is very strange... The error seems to say that there is some UTF-8 character in the file shown. However I see nothing of the sort, when I inspect the file myself (and I don't get this error). Can you look at the line 138 in the file to see if you find anything wrong? This line is part of a docstring, so you can try removing it to see what happens.
What python version are you using?
I'm using python 2.6. I solved by removing the reference in the documentation. that's weird indeed, opening the file with vim or less at that line didn't show anything worth mentioning! I finally managed to run grap_tool on my mac! :)
Cheers, Tiago
