Hi, I think this will likely be a system library related issue. However I am not familiar with the Centos operating system. Possibly Chris will be able to help you with this Cheers, Spencer.

I linked it with MKL, and was able to compile it, but it failed from test 5 till the last test (test 1 to 4 were successful though). My cmake command was ``` cmake\ -DCMAKE_CXX_FLAGS_RELEASE=" -I${MKLROOT}/include " \ -DNEKTAR_USE_MKL=ON \ -DMKL_LAPACK=${MKLROOT}/lib/intel64/libmkl_lapack95_lp64.a \ -DNEKTAR_USE_MPI=ON .. ``` I have tried linked with ThirdParty Boost following the FAQ page, but it does not help. I suspect the error was from linking with MKL? The deatailed error message was attached below.
