Dear all, With the new release of v4.0.1, we made some changes to the CMake configuration which have caused a few issues with third-party boost and fftw compilation on the Imperial cluster cx2. However, modules are now available for this software, so compilation is no longer necessary. I have updated the cx2 build instructions on the internal wiki. However for brevity, you should ensure the following modules are loaded: module load cmake/2.8.9 intel-suite mpi git fftw/3.3.3-double boost and use the following cmake configuration: CC=mpicc CXX=mpic++ cmake \ -DNEKTAR_USE_FFTW=ON \ -DNEKTAR_USE_MKL=ON \ -DNEKTAR_USE_MPI=ON \ -DNEKTAR_USE_SYSTEM_BLAS_LAPACK=OFF .. You will probably want to delete the builds and ThirdParty libraries before attempting to compile post-update.
