[gmx-developers] Circular dependencies makes linker a dull boy

[Erik Marklund]

Hi,

I, along with a few colleagues, am adding a few files to src/kernel/ as 
part of the implementation of qhop. I do get linker issues though, since 
force.c in src/mdlib/ uses a few functions found in src/kernel/qhop.c. 
In the end, this makes the kernel library dependent on the mdlib and 
vice versa. Moving qhop.c to mdlib does not resolve this issue, as it 
too needs stuff from kernel. How can I resolve this? Do I need to 
shuffle around more files, force.c for instance?

Here's the error:
…
/home/erikm/source/GMX/qhop_git/gromacs/src/mdlib/force.c:1613: 
undefined reference to `mk_qhoprec'
collect2: ld returned 1 exit status
…

Cheers,
