[Trilinos-Users] Cannot compile ML

[Martin Vymazal]

Hello,

  I downloaded trilinos-10.6.2 and used my old script to configure the  
build. Unfortunately, the build fails with the following error message:

  78%] Building CXX object  
packages/ml/src/CMakeFiles/ml.dir/Coarsen/ml_agg_min_energy.cpp.o

If I understand it correctly, ml_agg_min_energy.cpp doesn't see the  
declaration of dgemm_, which is a lapack function. I have liblapack.so  
in /usr/lib and CMakeCache.txt in the main build directory of Trilinos  
contains the following line:

TPL_LAPACK_LIBRARIES:FILEPATH=/usr/lib/liblapack.so

I don't think I have any lapack headers installed. (I don't know if  
they are needed or not). Does anyone have an idea what am I doing  
wrong? The script I use to configure cmake is attached. I'd be  
grateful for any suggestions.

Best regards,

  Martin Vymazal
