Hi I have been trying to build scipy on win2k (Python 2.3, scipy cvs ver. '0.2.1_252.4501') using MinGW. One problem in the build process is a strange call to a program "g" when building the cluster module (the other is a problem building the specfun library), a possible solution can be found by making a change in scipy_distutils: mingw32_support.py As far as the cluster build problem is concerned: compiling scipy with "python setup.py build --compiler=mingw32" results in the following error: "g -shared build\temp.win32-2.3\Release\lib\cluster\src\vq_wrap.o -Lc:\python23\libs -Lc:\python23\PCBuild -Lbuild\temp.win32-2.3 -lpython23 -lrootfind -lc_misc-lcephes -o build\lib.win32-2.3\scipy\cluster\_vq.pyd error: command 'g' failed: No such file or directory" I have tracked down the probable source of this problem in mingw32_support.py: Line 96: self.compiler_cxx = 'g++' If I understand it correctly MinGW uses python distutils UnixCCompiler which in unixccompiler.py has: Line 174: if target_lang == "c++" and self.compiler_cxx: Line 175: linker[0] = self.compiler_cxx[0] I think this is the source of the phantom "g" call. In mingw32_support.py altering Line 96: Line 96: self.compiler_cxx = 'g++' Line 96: self.compiler_cxx = ['g++'] seems to sort this problem out. I'm not at all sure if this is a proper solution to this problem or not, any comments or questions are more than welcome. Best regards Brett -- Brett G.
