OK, I've checked in all these changes.
- cygwin_compiler.py: [...] * changed result type of check_config_h() from int to string
I finally figured out how 'check_config_h()' should work; I've implemented it, tested it, and will check it in shortly. Here's the current code; please sanity-check it for me! (It works for me under Linux, at least.) ------------------------------------------------------------------------ def check_config_h(): """Check if the current Python installation (specifically, config.h) appears amenable to building extensions with GCC. Returns a tuple (status, details), where 'status' is one of the following constants: CONFIG_H_OK all is well, go ahead and compile CONFIG_H_NOTOK doesn't look good CONFIG_H_UNCERTAIN not sure -- unable to read config.h 'details' is a human-readable string explaining the situation. Note there are two ways to conclude "OK": either 'sys.version' contains the string "GCC" (implying that this Python was built with GCC), or the installed "config.h" contains the string "__GNUC__". """ # XXX since this function also checks sys.version, it's not strictly a # "config.h" check -- should probably be renamed... from distutils import sysconfig import string,sys # if sys.version contains GCC then python was compiled with # GCC, and the config.h file should be OK if string.find(sys.version,"GCC") >= 0: return (CONFIG_H_OK, "sys.version mentions 'GCC'") fn = sysconfig.get_config_h_filename() try: # It would probably better to read single lines to search. # But we do this only once, and it is fast enough f = open(fn) s = f.read() f.close() except IOError, exc: # if we can't read this file, we cannot say it is wrong # the compiler will complain later about this file as missing return (CONFIG_H_UNCERTAIN, "couldn't read '%s': %s" % (fn, exc.strerror)) else: # "config.h" contains an "#ifdef __GNUC__" or something similar if string.find(s,"__GNUC__") >= 0: return (CONFIG_H_OK, "'%s' mentions '__GNUC__'" % fn) else: return (CONFIG_H_NOTOK, "'%s' does not mention '__GNUC__'" % fn) ------------------------------------------------------------------------ The new use of 'check_config_h()' can be seen in the current CVS version of cygwinccompiler.py. Please let me know ASAP if this works for you; release 0.9.1 is long overdue, and we need to stop screwing around and get it out the door!
