Depending on how your libmopac.a was biuld, you need the to include the f2c or g2c library as well.

> Hi 
> I am trying to link mopac with gromacs in a 32 bit linux machine. I have downloaded the libmopac.a file and kept it under /usr/local/lib. I installed fftw with double precision and then I set the enviornmental variables for linking mopac and gromacs 
> export LDFLAGS="-L/usr/local/lib  -Wl,--wrap,__ctype_b"
> export CPPFLAGS="/usr/local/include -DUSE_MOPAC"
> export LIBS="lmopac

> then I have ran the ./configure --with-qmmm-mopac --disable-float.It seems to run ok.Then I used the make command but an error is comming as follows-
