Hello, using vanilla distutils with vanilla Python 2.5, I would like to pass different extra_compiler_args to the setup() call based on the compiler I'm using. In fact, if I'm using GCC (whether on Windows, Linux or Mac), I have a few options to specify; if I'm using MSVC (on Windows), I have others. This looks like a basic need, but I couldn't find a way to achieve it. Most existing scripts in the wild seem to simply do a check on the platform, which neglects the fact that one can specify --compiler=mingw32 to use GCC MinGW to build on Windows. Any suggestion on how to achieve this? -- Giovanni Bajo Develer S.r.l. http://www.develer.com
