I attempted to build my research group's molecular simulation code. Compiling
appears to proceed normally, but linking fails with a string of spurious
multiple definition errors, e.g.
nucleation.o(.bss+0x0): multiple definition of `__nucleation_MOD_atomicpress'
nucleation.o(.bss+0x0): first defined here
However, running nm on nucleation.o shows only one line for the referenced
symbol:
0000000000000000 B __nucleation_MOD_atomicpress
And a grep of the program source shows that atomicpress is only declared in
module nucleation, so there is no apparent source for the complaints.
This code has been compiled and linked successfully with ifort 11 and a version
of pathf95 (either 2.5 or 3.0).
