Hi Gerrit,
I am having the same problem in 32-bit machine. The error message is :
cc -O3 -fomit-frame-pointer -finline-functions -Wall -Wno-unused -malign-double
-funroll-all-loops -o mdrun glaasje.o gctio.o init_sh.o ionize.o do_gct.o

../mdlib/.libs/libmd.a(qm_gamess.o)(.text+0x351): In function `init_gamess':
qm_gamess.c: undefined reference to `inigms_'
collect2: ld returned 1 exit status
I used nm /root/GAMESS-UK-7.0/m4/libgamess.a | grep "ver_c" to know the
number of underscore and its output:
0000e390 T ver_casa__
0001a810 T ver_casb__
00001490 T ver_ccsd__
00000b3e T ver_c__
0001ac90 T ver_cphf__
U ver_c__
U ver_casa__
U ver_casb__
U ver_ccsd__
U ver_cphf__
suggested that the compiler attached double underscore. Accordingly I export
the following to suppress it:
export LIBS='-lgamess -lg2c -lm -fno-second-underscore'
Unfortunately, having the same problem.
With regards,
Abu
