Hi all

I am trying to install Nektar++ for the first time, on Linux 4.18.6 with CMake version 3.12.1. 

The compilation fails with:

[ 66%] Linking CXX executable CardiacEPSolver
/usr/bin/ld: CMakeFiles/CardiacEPSolver.dir/CellModels/CellModel.cpp.o: undefined reference to symbol 'pthread_condattr_setclock@@GLIBC_2.3.3'
/usr/bin/ld: /usr/lib/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [solvers/CardiacEPSolver/CMakeFiles/CardiacEPSolver.dir/build.make:465: solvers/CardiacEPSolver/CardiacEPSolver] Error 1
make[1]: *** [CMakeFiles/Makefile2:2907: solvers/CardiacEPSolver/CMakeFiles/CardiacEPSolver.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

if I disable CardiacEPSolver in the configuration, I get a similar error:

[ 70%] Linking CXX executable CompressibleFlowSolver
/usr/bin/ld: CMakeFiles/CompressibleFlowSolver.dir/ArtificialDiffusion/ArtificialDiffusion.cpp.o: undefined reference to symbol 'pthread_condattr_setclock@@GLIBC_2.3.3'

make[1]: *** [CMakeFiles/Makefile2:2925: solvers/CompressibleFlowSolver/CMakeFiles/CompressibleFlowSolver.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

Can someone point me in the right direction?

Thanks, Mikkel
