[gpaw-users] Install problem (_gpaw.so,python library)

[Ask Hjorth Larsen]

Hi,

I have seen stuff like this on previous occasions.  Probably:

1) You need to add 'gfortran' to libraries in the customize file (this will
give you things like the gfortran string concatenate symbol)
2) If this is not sufficient, be sure to use the environment variable
LD_LIBRARY_PATH=<directory> at runtime or, better, at compile time by
appending '-Wl,-rpath=<directory>' to the customize file's extra_link_args.
3) You need to find libpython.a or libpython.so and link it.  I have
sometimes had very stupid compilers (IBM XL, I am looking at you) mess
things up and fail to find it no matter how obvious paths were given to
it.  You give it an absolute path and still it cannot find that library
because it somehow strips off part of the path (WTH).  If that's a problem,
try symlinking libpython.a into the source directory.

Best regards
Ask
