It sounds like you have a mixed LFN _and_ compiler problem.

When you compile with gcc a cpp/C/cc file, the compiler will compile it in a C++ fashion,
but you have to include all libs in the compiling process. So, gxx will solve your problem,
because it will put -lstdcxx for you:

gcc -o dpf.exe dpf.cc -lstdcxx    ==    gxx -o dpf.exe dpf.cc

or something similar.
Then, back to the LFN problem. If you installed your compiler with a long file names capable
unzipper, like WinZip, LFN=y should work fine. If you installed it from the DOS prompt with
unzip, pkunzip or so on, you'd better put the LFN=n line in your DJGPP.ENV file.

Regards,

        Flavio.
