Re: [Numpy-discussion] Inquiry Regarding F2PY Windows Content
Then how about known combinations of version numbers for g77/gcc, python, and numpy? The gist would be to convey something that is known too work together. Some of the magic under the hood is looking at system environmental variables, and the Intel fortran compiler flags wreak havoc, requiring the uninstall of the intel compiler to prevent corruption of the gnu95 setup w/ gfortran. Something on where to look to see whats going on would be helpful!

Re: [Numpy-discussion] Inquiry Regarding F2PY Windows Content
The default finds both the g77 gfortran compilers. The issue is that the flags associated w/ both appear to be corrupted by the contents of the intel fortran environmental variables (i.e. content matched, removal of the intel system environmental variables made the problem go away), resulting in the example problem failing. Used f2py/diagnose.py to verify. It's just that it took about six python install/uninstall cycles. It would be nice to enable others to avoid the problem via a heads-up on the F2Py Windows web page. -Original Message- From: numpy-discussion-boun...@scipy.org [mailto:numpy-discussion-boun...@scipy.org] On Behalf Of David Cournapeau Sent: Wednesday, June 10, 2009 8:44 AM To: Discussion of Numerical Python Subject: Re: [Numpy-discussion] Inquiry Regarding F2PY Windows Content On Thu, Jun 11, 2009 at 12:30 AM, Carl, Andrew F (AS)a.c...@ngc.com wrote: Then how about known combinations of version numbers for g77/gcc, python, and numpy?

See issue #2234 in http://www.python.org/download/releases/2.5.4/NEWS.txt That's not really the problem I had in mind - rather, if you compile your extension with gfortran, since numpy is built with g77 on windows, you can get into hairy situations since g77 and gfortran are not compatible. If you build numpy yourself with gfortran (which should work), then there is no problem.

Got gfortran (dated 2009-04-21) working w/ python 2.5.2, numpy 1.3.0 MinGW 5.1.4, and after removing the intel fortran system environmental variables (plus six python installs, a intel fortran uninstall, and a day and a half of head scratching).

Re: [Numpy-discussion] Inquiry Regarding F2PY Windows Content
PC w/ Windows XP [Version 5.1.2600] Steps: 1) Follow steps 1 thru 3 from F2py Windows web page, in my case as follows: a) ActiveState ActivePython 2.5.2.2 b) Numpy 1.3.0 c) gFortran (dated 2009-04-21) 2) Install MinGW 5.1.4 (g++, g77, make) 3) Check system environmental variables as follows: a) PATH: C:\gfortran\libexec\gcc\i586-pc-mingw32\4.5.0;C:\gfortran\bin;C:\MinGW\b in b) C_INCLUDE_PATH: C:\gfortran\include 4) Run C:\Python25\Lib\site-packages\numpy\f2py\diagnose.py and review output for g77 g95 fcompilers found contents of flags: a) GnuFCompiler instance: c:\MinGW\gin\g77.exe b) Gnu95FCompiler instance: c:\gfortran\bin\gfortran.exe c) If you don't see items a b above, don't bother trying the example problem from the F2py Windows web page 5) same as step 5 from F2py Windows web page To make matters worse, an install/uninstall of ipython from Add or Remove Programs broke it, requiring the entire process to be repeated (i.e. uninstall/re-install numpy scipy alone did not work). THIS IS SCARY (and frustrating)!
