I've just skimmed the thread, so sorry if this has been already answered. First of all, have you tried compiling/linking using gfortran instead? It supports not just Fortran95 and later, but also Fortran77. g77 is just a Fortran77 compatibility compiler, in case you have code that uses the very few g77 intrinsics that aren't supported by gfortran yet (this got even better again in GCC 4.3). Second, I saw the you have *.f and *.c sources, are you sure the latter are C++ and not plain C (then you should just compile them using a C compiler and don't need C++ compiler)? If the answer for both of the above is that you really have to use g77 and the sources are in C++, then make sure you have also compat-gcc-34-c++ package installed and compile the C++ sources using g++34, F77 sources using g77 as you did and finally just link with g77. If compat-gcc-34-c++ is installed, then g77 will be able to find the GCC 3.4 compatibility libstdc++. Also, you should learn to put -lstdc++ and other -l* options last on the command line, not first - while the above works for shared libstdc++, it wouldn't work for static link.
