Well I am using gcc 4.3.3 and while c++ works, I can't get the C++ standard libraries to compile when cross compiling (which is of course the only way one can compile for the coldfire). Fortunately I have no need for the C++ libs at all on the coldfire, just the compiler so it works for me. Older versions of gcc cross compile fine, but 4.3 really messed up the autoconf scripts and now simply can not be cross compiled. It needs to do compile/link/run tests in some parts of the libraries. elf2flt tells ld how to do its job, so it really does get involved in the work. gdb only supports the elf files, which is what the .gdb file is. It is almost certainly a different elf binary than you would have gotten by running ld by itself though. -- Len Sorensen _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
