I'm new to write configure.ac scripts so I didn't know that I can choose xyz instead yes and no.

That means in configure the following should be possible: configure --enable-device=devicea or configure --enable-device=deviceb or configure --enable-device=devicec or .... If yes it should work fine for me and I have to do some experiments with AC_ARG_ENABLE. > > 2) > > --devicexresoluton=x > > --deviceyresolution=y > > --enable-devicexresolution=x > > > or even better > > > > --deviceres=x*y > > This is up to you.

But that means that I must define any possible resolution in configure.ac, right? And the resoultution is not give like this to config.h #define XRES 320 #define YRES 240 but like this #define RES320X240 or #define RES640X480 Do I understand right? Ok it is not so flexible but I think I can live with this. It seams my problems can be solved with AC_ARG_ENABLE and AC_ARG_WITH, at least if it is possible to have more than 2 options and only yes and no. Maybe I "only" have to learn more about this. Some examples to this or a tutorial page would be helpfull. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
