I get undefined symbol errors when I try to compile programs with calls to mmap(). If mmap() has not yet been implemented, I was given an implementation called mman.c written by a fellow in Australia, David Makepeace , which says it implements mmap using the Win32 memory mapping routines. I cannot compile this version of mmap under gcc on Windows NT, however, because it references a function called _get_osfhandle. This seems to be defined in the Microsoft LIBC, but not in the gnu-win32 libraries. Can anyone tell me how to link with this function, or more generally how to link with a .lib or other object file produced by Mirosoft's compiler? Thanks, Henry - For help on using this list, send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
