Hello,
  I’m sorry that you’re having troubles with building on windows. Right now we really only test with clapack on windows and there is a slight difference in how we find the blas and lapack tpls on windows that is likely causing this issue. There are two things you can try to fix this though. First, we’ve found that cmake likes to remember that it failed to find tpls. So if you can’t find a tpl, then set the appropriate <tpl name>_LIBRARY_DIRS and reconfigure  without deleting the CMakeCache.txt file first cmake will continue to report that it couldn’t find the tpl. You should delete the CMakeCache.txt file and try reconfiguring with BLAS_LIBRARY_DIRS set to the path to your blas library. If that doesn’t work you can try setting TPL_BLAS_LIBRARIES to the absolute path to your blas library file. You should also delete the CMakeCache.txt before reconfiguring with that option as well.

Brent

Hi,

I've been desperately trying to build trilinos on windows using CMake for two days now. I set up the source folder and the folder where to build the binaries. I'm using Visual Studio 9 (2008) for the compilers. I'm enabling only two packages (which I need: Amesos and AztecOO).
I've also installed LAPACK v3.1.1, but I always get the same error, saying that the BLAS library can not be found. I get this error although I've set an entry in Cmake for 'BLAS_LIBRARY_DIRS', which points to the folder where the blas.lib and lapack.lib files are located.
Here is the log:

Processing enabled TPL: BLAS
   Searching for library 'blas' ...
   Searching for library 'blas_win32' ...
   Warning: Could not find a library in the set "blas blas_win32" 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/tribits/package_arch/TribitsProject.cmake:96 (TRIBITS_PROJECT_IMPL)
   CMakeLists.txt:85 (TRIBITS_PROJECT)


Please help me. What can I do, I really need Trilinos in order to run another project. Is there an easier way to build Trilinos on Windows?
Thank you very much.

Best Regards,
Lucian Itu
