numpy 1.1.0 build can not find lahey (lf95) fortran compiler (short version)
Hi, When trying to build numpy 1.1.0 with python 2.5.2 on an RHEL3 32-bit system, using command: python setup.py config_fc --fcompiler=lahey install &> install_LEW.log I am seeing these warnings: warning: build_ext: f77_compiler=lahey is not available. and warning: build_ext: extension 'numpy.linalg.lapack_lite' has Fortran \ libraries but no Fortran linker found, using default linker Then lapack_lite.so is linked incorrectly with gcc instead of lf95. File distutils/fcompiler/lahey.py is being read but the information inside is not being used. --Lew ---------------------------------------------------------------------- Lewis E.

Hi Lewis, What happens when you execute directly the file numpy/distutils/fcompiler/lahey.py ? cheers, David
Hi, When executing numpy/distutils/fcompiler/lahey.py, I get "none" Here is what I get from the following command.

Found the problem. The pattern in lahey.py differs from the version of Lahey Fujitsu compiler I have. Once corrected, the compiler is now found. P.S. One of the libraries defined in the file is also incorrect. Once I have gotten all the way through the SciPy build and the users have said all works, I'll send in the version of the successful lahey.py. Thanks for the help. Also thanks to the original contributor of lahey.py. It saved me a lot of time! --Lew -----Original Message----- From: numpy-discussion-bounces@scipy.org [mailto:numpy-discussion-bounces@scipy.org] On Behalf Of David Cournapeau Sent: Monday, June 02, 2008 8:23 AM To: Discussion of Numerical Python Subject: Re: [Numpy-discussion] numpy 1.1.0 build can not find lahey (lf95) fortran compiler (short version) Lewis E.

Ok, thanks for going through this. Can I ask you one more thing ? Can you give us the output of the Lahey fortran compiler output ? Such as we can add one test to the version parsing and avoid getting bitten by this next time cheers, David
