Also, I have read the draft and I cannot see references to 64-bit binary packages. With the advent of Windows 7 and Mac OSX Snow Leopard, 64-bit are way more spread than before, so they would be a great thing to deliver, IMO.
For Mac OS X, we should wait for official 64 bits binaries from python.org - EPD offers 64 bits binaries if necessary. On windows, the situation is more complicated, because there is no way to build numpy and scipy correctly with free compilers. For various reasons, I think we should avoid distributing binaries based on non-free compilers (not available to everyone, problem of compatibility and redistribution of non-free code, especially for fortran) - and for people who don't mind/care, there are unofficial win64 binaries out there (we may put a link somewhere). Unfortunately, I don't think I will have much time to spend on making scipy and gfortran work together on win64 in the near future,
Ok. I've been having a try at mingw-w64 project:
with no success so far with build numpy:
$ python setup.py build --compiler=mingw32 [...] Found executable C:\mingw-w64_x86_64-mingw\mingw64\bin\gcc.exe g++ -mno-cygwin _configtest.o -lmsvcr90 -o _configtest.exe Found executable C:\mingw-w64_x86_64-mingw\mingw64\bin\g++.exe c:/mingw-w64_x86_64-mingw/mingw64/bin/../lib/gcc/x86_64-w64- mingw32/4.4.4/../../ ../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lmsvcr90 collect2: ld returned 1 exit status failure. [...]
However, I can compile it with plain mingw tool chain (obviously, only can get w32 binaries). Any hint on how to proceed with mingw-w64?
