install error

[Canjun Zhao]

Dear users,

I have used the command'make mpi_mbx -j 40 CXX=mpicxx' to install mpi_box, but generating the error message:

/usr/bin/ld: ./liblammps_mpi_mbx.a(platform.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:109: recipe for target '../lmp_mpi_mbx' failed
make[1]: *** [../lmp_mpi_mbx] Error 1

Could you please help me figure out what's wrong?

many thanks

Hello Canjun,

If you are still having this issue, try adding the line:

LIB += -ldl

to the Makefile.mpi_mbx anywhere after LIB is defined but before it is used.

This usually fixes this problem in our experience.
