Fortran Libs not importing properly

[ghost]

With build_lib set to true, from magic import * fails. Specifically, it has trouble import magic.legendre as leg which leads me to believe that the fortran libraries are not importing correctly. Any help would be greatly appreciated! Traceback:

Please wait: building greader_single...
Please wait: building greader_double...
Please wait: building lmrreader_single...
Please wait: building Legendre transforms...
Please wait: building vtklib...

Hi,
I've typically seen this occur while using python2. Do you have both python versions (2 and 3) installed on your computer?
One way to force it to use python3 might be to explicitly set f2pyexec = f2py3. Can you set that in the magic.cfg, remove the *.so files and try again?

Hi, thank you for the reply. It doesn't even look like the .so files are created. They are supposed to be in $MAGIC_HOME/python/magic correct?

[AnkitBarik]

I see. It's the compiler then. Could you send the following information?

• Is this on a cluster or a local computer?
• What compilers are you using (system variables: CC, FC, CXX) ?
• Can you paste your magic.cfg ?

[ghost]

Local computer, CC=gcc, FC=gfortran, CXX=mpicxx
magic.cfg:

[plots]
Adapt your backend to your machine: 'TkAgg', 'GTKAgg', 'Qt4Agg', ...
backend = TkAgg
In case you don't have LaTeX installed switch to False
labTex = False
Default colormap
defaultCm = seismic
Default number of levels
defaultLevels = 65
[libraries]
adapt this value if you don't want libraries
buildLib = True
f2py executable, can be f2py, f2py2 or f2py3 (python 3)
f2pyexec = f2py3
fortran compiler: f2py -c --help-fcompiler, frequently 'intelem' or 'gnu95'
fcompiler = gfortran
c compiler: f2py -c --help-compiler
No need to touch this one except on gwdg, change it to intelem
ccompiler = gcc

[AnkitBarik]

You need to set fcompiler=gnu95 and leave the ccompiler to the default value of unix.
Edit: These should get set automatically if you source the sourceme.sh script: source /path/to/magic/sourceme.sh

[ghost]

Ah, that worked! Thought I had already tried gnu95 as my fortran compiler but apparently not. Thank you!
