Problems when compiling in it++ test direcory

[Anonymous]

Hi,

I have compiled it++3.7.1,
atlas3.4.1_Linux_P4SSE2, lapack under  Cygwin.
I have the problem that the comilation result of it++ looks ok. But problems always occure when
running 'make test' in the itt++/tests directory.
Has anyone an Idea what get's wrong ?
It looks for me that something with BLAS does not work.

thanks

Hi Manuel,

You probably need to check that your soft links in the it++/lib directory are correct. Assuming that you use ATLAS and netlib-LAPACK you need to add the followin soft links in the it++/lib directory:

ln -s <ATLAS_LIBDIR>/libatlas.a ./libatlas.a
ln -s <ATLAS_LIBDIR>/libcblas.a ./libcblas.a
ln -s <ATLAS_LIBDIR>/libf77blas.a ./libf77blas.a
ln -s <ATLAS_LIBDIR>/liblapack ./liblapack.a

Make shure that you have a complete LAPACK lib file in your ATLAS_LIBDIR folder (see the installation section in the IT++ getting started manual on how to do that).

When the soft links are OK you need to re-run the configure script to regenerate the it-config script in the it++/bin folder.

Also make shure that you use the same GCC compiler version for ATLAS, LAPACK and IT++. If you use different versions of GCC for the different libraries you will have problems.

On Cygwin I have tested with ATLAS 3.5.5, netlib-LAPACK 3.0 and GCC 3.2 20020927 (prerelease) and that works fine. Other combinations will probably work as well but we haven't tested them.

Good luck
