The gcc manual page is somewhat confusing on this topic but as I understand it, when processing a library, it only considers symbols which were already referenced but not defined, and discards the rest. So object files must indeed come first on the command line. Why it has always worked for me the other way around is a mystery. You have write permissions to the repository, so please just commit this fix, thanks. -- Jean Delvare -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
