Hi Syavash,

A few questions pop up on my mind on seeing this:

1. What compilers are you using  (GCC or Intel?)
2. Are you loading the modules which are compatible with the compiler you are using?
3. Do you have a version of OpenBLAS or MKL already loaded as one of the modules on your cluster?

As often is the case, the problem might be more detailed and it’ll be great to see the modules and cmake commands you are using for you installation in order to debug this properly. Happy to hop on a call if needed!

Best

Hi Everyone,

I am trying to install the latest version of Nektar on a cluster. However, I get the following error at some point:

../../library/SpatialDomains/libSpatialDomains.so.5.3.0: error: undefined reference to '__intel_sse2_strlen'
../../library/SpatialDomains/libSpatialDomains.so.5.3.0: error: undefined reference to '_intel_fast_memcpy'
../../library/SpatialDomains/libSpatialDomains.so.5.3.0: error: undefined reference to '_intel_fast_memset'
collect2: error: ld returned 1 exit status
make[2]: *** [utilities/NekMesh/CMakeFiles/NekMesh.dir/build.make:106: utilities/NekMesh/NekMesh] Error 1
make[1]: *** [CMakeFiles/Makefile2:1647: utilities/NekMesh/CMakeFiles/NekMesh.dir/all] Error 2
make: *** [Makefile:141: all] Error 2

I had "NEKTAR_USE_SYSTEM_BLAS_LAPACK:BOOL=ON " and "THIRDPARTY_BUILD_BLAS_LAPACK:BOOL=ON" in the ccmake as per suggested in the user archives.

I appreciate your kind help.

Kind regards
