[f2py] Problems w/f2py on Windows, Intel Fortran (resend as member)

[Paul Magwene]

Hello f2py users,

I'm having problems using f2py on WinXP using the Intel Fortran Compiler
(v8.1). My problem appears similar to a previous inquiry described here:

http://cens.ioc.ee/pipermail/f2py-users/2004-November/000971.html

However, I can't seem to resolve the issue as the previous poster did.
It looks like when I use the compiler argument --fcompiler=intel then
the object file hello.o does not get built. When I use the argument
--fcompiler=intelv the libraries can't be found (though they're
correctly set with the environment variable LIB).

I'd like to use some features of Fortran 90 so using g77 via
cygwin/mingw doesn't work for me. Has anybody else gotting f2py working
smoothly on Win32 using the Intel Fortran compiler?

Thanks,
Paul



My relevant configuration info is:

WinXP
Python 2.3.4
F2PY (F2PY-2-latest.win32.exe -- Downloaded 3 January 2004)
scipy_distutils-latest.win32.exe (downloaded 3 January 2004)
Intel Fortran compiler v8.1 (w_fc_pc_8.1.025)


I'm trying to build a simple 'hello.f90':


! File hello.f90
subroutine foo (a)
integer a
print*, "Hello from Fortran!"
print*, "a=",a
end

I'm running f2py from the command line as follows:

f2py.py --build-dir . -m hello -c --fcompiler=intel hello.f90

The output and error message I get is:

When I try building with --fcompiler=intelv I fail with:

This is despite the fact that the proper lib is defined in the
environment variable "LIB"

Responding to my own message...

It turned out the problem seemed to be related to having both VC6 and
VC7 installed (and maybe also because Python 2.3 is built with VC6, but
the intel 8.1 compiler requires VC7 (?)).

Anyhow, for anyone else with a similar setup, make sure that the VC7
directories appear ahead of the VC6 directories in your path. Also,
after some bumbling around I figured out that the library directories
need to be specified before the other arguments, like so:

f2py.py -L"%INTEL_FORTRAN80%\ia32\lib" -c hello.f90 -m hello
--fcompiler=intelv --build-dir .

Cheers,
Paul
