I am using REDHAT linux fedaro. It is said that Autoconf package can be used to determine features provided by system: Are System V message queues supported? is the uint8_t datatype defined? is the gethostname function provided? and so on.Can Autoconf generate a 'config.h' file for all these? If can ,can anyone tell the routine. Thanks a lot _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
