I have recently installed Microcross's version of gcc for arm under Cygwin on Windows/XP - my first experience with gcc. I have been able to compile to elf object format, link, and execute a trivial program on my target board. But now I am trying to execute something simple (more than trivial) and I am getting error messages from the loader like "undefined reference to 'strlen' " and "undefined reference to '__udivsi3'" (a signed integer divide operation is in the source).. I suspect that the libc (and possibly other libraries) are not being found by the loader. These appear to be located at C:\Cygwin\usr\arm-elf\lib. I have tried several ways of specifying that path through $LIBPATH and -L directives, but I keep getting the same errors. Does anyone know how to solve this problem? When I finally get to the right library path, where will __udivsi3 be found?
