Can't compile on Ubuntu 20.04 LTS with boost 1.65.1 compiled from source

[Vyrgyl]

Hi,

I've been trying to compile feelpp from this source repository using boost 1.65.1 that I compiled with GCC (shared and statically). The first error I have is:

[ 60%] Building CXX object feelpp/contrib/ginac/tools/CMakeFiles/viewgar.dir/viewgar.cpp.o
[ 61%] Linking CXX executable viewgar
/bin/ld: ../ginac/libfeelpp_ginac.so.6.0.1: undefined reference to `boost::mpi::communicator::operator int() const'
collect2: error: ld returned 1 exit status
make[2]: *** [feelpp/contrib/ginac/tools/CMakeFiles/viewgar.dir/build.make:108: feelpp/contrib/ginac/tools/viewgar] Error 1
make[1]: *** [CMakeFiles/Makefile2:4167: feelpp/contrib/ginac/tools/CMakeFiles/viewgar.dir/all] Error 2
make: *** [Makefile:166: all] Error 2

When I utilize the command 'nm -C libboost_mpi.so | grep "operator"'

U operator new[](unsigned long)@@GLIBCXX_3.4
U operator new(unsigned long)@@GLIBCXX_3.4

So obviously there is no "boost::mpi::communicator::operator int()"

Even tho 'nm -C libboost_mpi.a | grep "boost::mpi::communicator::operator"'

             U boost::mpi::communicator::operator ompi_communicator_t*() const

00000000000000f0 T boost::mpi::communicator::operator ompi_communicator_t*() const
U boost::mpi::communicator::operator ompi_communicator_t*() const
U boost::mpi::communicator::operator ompi_communicator_t*() const

Is there an incompatibility issue with that particular version of Boost?

Thank you

Hello @Vyrgyl thank you for your report. We do compile feelpp on 20.04 have you installed libboost-all-dev ? it is actually boost 1.71 and not 1.65.
