"""distutils.cygwinccompiler Provides the CygwinCCompiler class, a subclass of UnixCCompiler that handles the Cygwin port of the GNU C compiler to Windows. It also contains the Mingw32CCompiler class which handles the mingw32 port of GCC (same as cygwin in no-cygwin mode). """ # problems: # # * if you use a msvc compiled python version (1.5.2) # 1. you have to insert a __GNUC__ section in its config.h # 2. you have to generate an import library for its dll # - create a def-file for python??.dll # - create an import library using # dlltool --dllname python15.dll --def python15.def \ # --output-lib libpython15.a # # see also http://starship.python.net/crew/kernr/mingw32/Notes.html # # * We put export_symbols in a def-file, and don't use # --export-all-symbols because it doesn't worked reliable in some # tested configurations. And because other windows compilers also # need their symbols specified this no serious problem. # # tested configurations: # # * cygwin gcc 2.91.57/ld 2.9.4/dllwrap 0.2.4 works # (after patching python's config.h and for C++ some other include files) # see also http://starship.python.net/crew/kernr/mingw32/Notes.html # * mingw32 gcc 2.95.2/ld 2.9.4/dllwrap 0.2.4 works # (ld doesn't support -shared, so we use dllwrap) # * cygwin gcc 2.95.2/ld 2.10.90/dllwrap 2.10.90 works now # - its dllwrap doesn't work, there is a bug in binutils 2.10.90 # see also http://sources.redhat.com/ml/cygwin/2000-06/msg01274.html # - using gcc -mdll instead dllwrap doesn't work without -static because # it tries to link against dlls instead their import libraries. (If # it finds the dll first.) # By specifying -static we force ld to link against the import libraries, # this is windows standard and there are normally not the necessary symbols # in the dlls. # *** only the version of June 2000 shows these problems # * cygwin gcc 3.2/ld 2.13.90 works # (ld supports -shared) # * mingw gcc 3.2/ld 2.13 works # (ld supports -shared) # This module should be kept compatible with Python 2.1. __revision__ = "$Id$" import os,sys,copy from distutils.ccompiler import gen_preprocess_options, gen_lib_options from distutils.unixccompiler import UnixCCompiler from distutils.file_util import write_file from distutils.errors import DistutilsExecError, CompileError, UnknownFileError from distutils import log def get_msvcr(): """Include the appropriate MSVC runtime library if Python was built with MSVC 7.0 or later.
