Problems to use Quantlib

[Diallo Amadou]

Hello
I installed under mandrake 10.0 Quandlib. But when I make a program at
c++ and I compile it I have a error witch I give by attachement. I
want to have some indications for to use correctly quantlib:
My programm is :

#include <ql/quantlib.hpp>
#include <iostream>
int main (int,char* []){
}

Commande compilation is
gcc -I"include" -L"lib" test.cpp

Thanks

I would try

g++ -I"include" -L"lib" -lQuantLib test.cpp

Dear Kind Soul,

I'm pulling my hair at QuantLib-SWIG-0.3.11 compilation failure in
cygwin: configure doesn't
seem to generate the proper flags for gcc --

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

There are two ways to write error-free programs; only the third one  
works.

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) --

[hidden email]
(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 --

[hidden email]
(Tue Mar 14 21:03:38) $ grep -r strict-prototypes .
[hidden email]
(Tue Mar 14 21:04:04) $

Thanks!

Jerry

I see. But if you compiled QuantLib in VC++, you'll have to use the  
same compiler for the Python extension as well---and use Python for  
Windows, not the one coming with cygwin. Cygwin will try to use gcc, so  
it will need a library compiled with gcc. You'll have to cd to the  
QuantLib-SWIG/Python directory and run "python setup.py build" from a  
DOS shell.
