I'm not having any luck finding this in the autoconf manual. I need to compile and link in my embedded OS, but I want to choose the top-level path to the OS because I have different versions. The embedded OS has its own make system that does not use autoconf. (So I wouldn't use AC_CONFIG_SUBDIRS.) In my configuration script, I have a top-level directory variable defined "ac_os_dir=/cygdrive/c/os_dir" and many path variables and strings built from ac_os_dir such as: ac_os_includes, ac_os_ldscripts, ac_os_boothdr, ac_os_image_header, ac_os_binpack, etc. The OS compiles into libraries using its own makefiles, but to link the final installation image I need to have all the paths to the linker scripts and image packager. I want to set the 'ac_os_dir' on the configure command line. I see AC_ARG_ENABLE and AC_ARG_WITH both sort of expect the value to be "yes" or "no", and not a directory. I tried AC_ARG_WITH(myos, ...) and then used -with-myos and -myos-libraries=/cygdrive/c/libpath but these were not understood. (I thought it might work like -x-libraries=path) I am pretty sure AC_ARG_VAR will work, but is this at all the right way to do it? What I most want is something like: ./configure -ospath=/cygdrive/c/path Customers will never install using this configure. The configure is for developers only. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
