Hi guys, I'm trying to install Sandia's SST when I encountered this error while running the configuration script. checking for doxygen... no checking for mpicc... mpicc checking for MPI_Init... yes checking for mpi.h... yes checking for mpic++... mpic++ checking for mpi.h... yes checking how to run the C preprocessor... gcc -E checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking for boostlib >= 1.41... yes checking whether the Boost::Program_Options library is available... yes configure: error: Could not link (link_program_options) against ! I installed my BOOST libraries via Ubuntu's Synaptic, and I have installed libboost-program-options-dev, libboost-program-options1.46.1 and libboost-program-options1.46-dev. Any ideas on how to fix the error? Any help would be appreciated. =)
