Or the method autoconf uses - binary search, using a compile-time numeric comparison which resolves to a successful or failed compile. That seems more portable to me. Relying on 'nm 'finding the variable, and not accidentally matching another variable with the wrong value, does not work for all C environments. E.g. some compile to compressed executables; some produce intermediate objects with incomplete or lazy compiles or symbolic, to be finished at link stage, and some are even more abstract. And it requires the 'nm' tool, which you might not have for cross-compilation, or might not find the right one. -- Jamie -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
