Category: Build Group: Python 2.5 Status: Open Resolution: None Priority: 5 Submitted By: Christoph Ludwig (cludwig) Assigned to: Nobody/Anonymous (nobody) Summary: Compiling and linking main() with C++ compiler Initial Comment: The attached patch proposes a resolution to the discussion started in <url:http://thread.gmane.org/gmane.comp.python.devel/69651> regarding the compiler (C vs. C++) used to compile python's main() and to link the executable. The patch contains the following changes: 1) The configure option --with-cxx is renamed --with-cxx-main. This was done to avoid surprising the user by the changed meaning. Furthermore, it is now possible that CXX has a different value than provided by --with-cxx-main, so the old name would have been confusing. 2) The compiler used to translate python's main() function is stored in the configure / Makefile variable MAINCC. By default, MAINCC=$(CC). If --with-cxx-main is given (without an appended compiler name), then MAINCC=$(CXX). If --with-cxx-main=<compiler> is on the configure command line, then MAINCC=<compiler>. Additionally, configure sets CXX=<compiler> unless CXX was already set on the configure command line. 3) The command used to link the python executable is (as before) stored in LINKCC. By default, LINKCC='$(PURIFY) $(MAINCC)', i.e. the linker front-end is the compiler used to translate main(). If necessary, LINKCC can be set on the configure command line in which case it won't be altered. 4) If CXX is not set by the user (on the command line or via --with-cxx-main), then configure tries several likely C++ compiler names. CXX is assigned the first name that refers to a callable program in the system. (CXX is set even if python is built with a C compiler only, so distutils can build C++ extensions.) 5) Modules/ccpython.cc is no longer used and can be removed. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1324762&group_id=5470 _______________________________________________ Patches mailing list [email protected] http://mail.python.org/mailman/listinfo/patches
