I have an extension for matlab that i want to compile. The machine on
which I compile the code has a g77-3.4 and a gfortran-4.2 compiler
installed. If I set the fortran compiler in the Makefile to g77-3.4 the
compilation process runs through without any error messages and I can
use the extension without any problems.
Compilation process with g77-3.4:

I'm wondering: Why does this happen? I have another machine on which I
would also like to compile the code but this machine doesn't have g77
installed.

You have to link with the gfortran-library. g2c only works with g77.
If you add "-lgfortran" to the link command, everything should work
well (I hope :-))

Thanks for the answers. I replace lg2c with lgfortran. When I try to
compile now I get the following error message

ld: warning: in /usr/local/gcc-4.3.5/lib/libgfortran.dylib, file was
built for i386 which is not the architecture being linked (x86_64)
Actually I build the /usr/local/gcc-4.3.5/lib/libgfortran.dylib by
myself some days ago. But somehow the compilation produced a 32 bit
library but I do need a 64 bit library. So I would like to rebuild the
gfortran stuff. But where do I have to configure that libgfortran.dylib
is compiled for a 64 bit system?
I built the gfortran stuff this way:
In "/Users/toom/Downloads/gcc-4.3.5-base/obj-gcc-4.3.5" I typed the
following commands:
../gcc-4.3.5/configure --prefix=/usr/local/gcc-4.3.5/ --languages=fortran
make
sudo make install
and I got a gfortran in /usr/local/gcc-4.3.5
So how to I tell the build process that I want a 64 bit compilation?

Now I got it to work. I found that within the lib directory that
contains the gfrotran libs exists another subdirectory called x86_64, i.e.
/usr/local/gcc-4.3.5/lib/libgfortran* (32 Bit)
and
/usr/local/gcc-4.3.5/lib/x86_64/libgfortran* (64 Bit)
And instead of linking the program like that...
$(MEX) -cxx CXX=$(CXX) CC=$(CXX) FC=$(FCC) LD=$(CXX)
-L/usr/local/gcc-4.3.5/lib -lgfortran -lm \
-O -output $@ $^
... I linked it like that...
$(MEX) -cxx CXX=$(CXX) CC=$(CXX) FC=$(FCC) LD=$(CXX)
-L/usr/local/gcc-4.3.5/lib/x86_64 -lgfortran -lm \
-O -output $@ $^
Now it works fine. Thanks for your help.
