Dear Luigi,

Hum... sys.platform in Cygwin returns 'cygwin'. In fact, I have already updated my setup.py to have the compiler settings portion directed to the original 'win32' section (primarily because I had my QuantLib compiled in MS VC and don't think Cygwin gcc would be able to link .lib or .dll successfully) --

(Tue Mar 14 21:05:27) $ vi setup.py
 ...
 76 #if sys.platform == 'win32':
 77 if sys.platform == 'cygwin':
 78     try:
 79         QL_INSTALL_DIR = os.environ['QL_DIR']
 80     except Exception, e:
 81         raise 'unable to detect QuantLib installation'
 82     include_dirs = [QL_INSTALL_DIR]
 83     library_dirs = [os.path.join(QL_INSTALL_DIR, 'lib')]
 84     libraries = None

My problem was more like how to get rid of the unrecognized/redundant compiler argument Wstrict-prototypes --

cl : Command line error D8021 : invalid numeric argument '/Wstrict-prototypes'

Where I couldn't find it anywhere in the package --

(Tue Mar 14 21:03:38) $ grep -r strict-prototypes .

(Tue Mar 14 21:04:04) $

Thanks!

Jerry

It seems like setup.py is getting confused. Can you run the following in a Python shell from cygwin and tell me what is returned?

import sys
print sys.platform
