Martin,
This is something I have seen before. You need to either create a soft link from libblas.so pointing to libblas.so.3, or you can just specify the entire path and library as your blas: -DBLAS_LIBRARIES=/usr/lib64/libblas.so.3

Subject: [Trilinos-Users] How to link libblas.so
Dear Trilinos users & developers,
I have trouble configuring trilinos (10.6.1) to detect blas. The
folder /usr/lib64 contains:
/usr/lib64//libblas.so.3 -> libblas.so.3.2.1
/usr/lib64//libblas.so.3.2 -> libblas.so.3.2.1
/usr/lib64//libblas.so.3.2.1
and I run cmake with the following options:
...
-D TPL_ENABLE_BLAS:BOOL=ON \
-D BLAS_LIBRARY_DIRS:PATH=/usr/lib64 \
-D BLAS_LIBRARY_NAMES:STRING="blas" \
...
And I always end up with the following:
Getting information for all enabled TPLs ...
-- Processing enabled TPL: MPI
-- Processing enabled TPL: BLAS
-- BLAS_LIBRARY_DIRS='/usr/lib64'
-- Searching for library 'blas' ...
-- Warning: Could not find a library in the set "blas" for the TPL
BLAS! Please manually set BLAS_LIBRARY_DIRS and/or BLAS_LIBRARY_NAMES
or just TPL_BLAS_LIBRARIES to point to the BLAS libraries!
CMake Error at cmake/package_arch/TPLDeclareLibraries.cmake:196 (MESSAGE):
Error, could not find the BLAS Library! Please manually set
BLAS_LIBRARY_DIRS and/or BLAS_LIBRARY_NAMES or just TPL_BLAS_LIBRARIES to
point to the BLAS libraries!
I don't have this problem when configuring with static blas library
(libblas.a) in a different machine.
Could you please tell me how to configure Trilinos properly? Thank you
very much.
Best regards,
Martin Vymazal
