> PC_base.z.o(.data+0x8): undefined reference to `TM_PC_95base' > PC_base.z.o(.data+0x3c): undefined reference to `TMSUB_PC_95base' I suspect this is a fault in the name-mangling part of our time profiler. Try renaming the module so that it does not have an underscore in it! (both the filename and the module name I guess.) Regards, Malcolm
