According to the suggestion I have installed the f2c package in my machine.I am unable to find the g2c package. I have included the f2c library by - export LIBS="-lmopac -lf2c". But when I running ./configure --with-qmmm-mopac --disable-float , an error is comming C compiler cannot create executable. The config.log file shows the following section- onfigure:3413: checking for C compiler default output file name configure:3440: cc -I/usr/local/include -DUSE_MOPAC -L/usr/local/lib conftest.c -lmopac -lf2c >&5 /usr/lib/gcc/i486-linux-gnu/4.3.3/../../../../lib/libf2c.so: undefined reference to `MAIN__' collect2: ld returned 1 exit status configure:3443: $? = 1 configure:3481: result: configure: failed program was: | /* confdefs.h. */ Please suggest a way out.Subarna Thakur
