Dear gerrit sir,
thank you for your reply Here I have got compilation error as follows

i am using the following command
./configure --disable-float --with-qmmm-mopac CPPFLAGS=-DUSE_MOPAC LIBS=-lmopac LDFLAGS=-L/usr/local/lib
i am expecting your useful reply Thanks in Advance

Without-qmmm-mopac will not lead to compilation of the mopac interface source code.
What is the compilation error?
