Hello again, After solving the config.sub and config.guess issue, I've found that configure keeps asking for install.sh, install-sh or shtool even when AC_PROG_INSTALL is not set in configure.ac. From what I understand from the manual, configure should only search for install-sh and related files when AC_PROG_INSTALL is set. "If you use AC_PROG_INSTALL, you must include either `install-sh' or `install.sh' in your distribution, or configure will produce an error message saying it can't find them--even if the system you're on has a good install program." I have a custom install.sh, but it is located in "./..", while config.guess and config.sub are in "." (related to where configure is), and I can set AC_CONFIG_AUX_DIR([./.. .]), but configure keeps failing, because it assumes config.sub, config.guess and install.sh are located in the same folder. Thanks, Roger. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
