Hi,
I don't know if it is right to pollute this list with my problems in trying to
compile graph-tool for Win64. I'll try to make it brief.
Using MSYS2/MinGW64, I managed to compile the whole src/graph modules
and install them as *.pyd modules in the site-packages/graph_tool directory,
along with the Python files.
Unfortunately, I get a segfault when importing graph_tool.libgraph_tool_core .
The segfault happens deep in libboost_python3.
Before posting a long backtrace, maybe someone may offer some clue on what is
happening. I have posted some details about what I did below.
If someone is interested and/or has ideas on how o go on, I'll be glad to share
and work on this problem.
(And I must say that I would love to get this tool to work under Windows,
because it seems to be one of the best of its kind!)
Best regards,
Fabrice
The background is: python 3.4, boost 1.57, clang 3.5.1 (g++ 4.9.2 as provided
with mingw64 couldn't compile a few objects witout segfaulting).
It is possible that there is a conflict among those libs/tools (of thread model
for example).
Currently I have configured like this:
./configure --enable-debug --disable-optimize CFLAGS="-I/mingw64/include"
LDFLAGS="-L/mingw64/lib" CC=clang CXX='clang -std=c++11 -m64 -DMS_WIN64=1'
CXXCPP='clang -E -std=c++11 -m64 -DMS_WIN64=1' PYTHON=python3
Then I run 'make -k -j 8' to compile all the objects. Linking the various dlls
fails, because under Windows, you can't link graph_tool_centrality.dll without
referencing grap_tool_core.dll.a. However the build process is not prepared to
do that and in the right order.
So I manually replicated what libtool does, ie :
clang -std=c++11 -shared -nostdlib C:/Local/MSys64/mingw64/x86_64-w64-

done
for i in `find . -name \*.dll` ; do cp $i /mingw64/lib/python3.4/site-
packages/graph_tool/`basename $i .dll`.pyd; done
At this point, the modules are installed.
The only thing to change on the Python side is to remove
the calls to getdlopenflags() and setdlopenflags() which are not available to
Windows.
