[gmx-users] mopac gcc g77 and x86_64

[Andrey V. Golovin]

Dear all,
I faced with common problem I think :)
Linux 64 bit, gcc and etc.
I can't link libmopac.a from
http://www.mpibpc.mpg.de/groups/grubmueller/start/people/ggroenh/qmmm.html
because last one is 32 ...
Building my own one with g77 or gfortran or f2c gives the same error

OR

gmxmop.f:(.text+0x2d4): undefined reference to `_gfortran_string_index'

and so on like no references defined at all.

Looks like something stupid here... Any idea?

PS Compiling mopac lib goes with some warnings but no errors.
