Dear autoconfers Sorry for over posting, but, even after RTFM, I don't understand something about variable... First : I don't understand why $abs_builddir is empty when I use it in my configure.ac (see below) Second : supposing prefix=/toto/ I don't understand why ${includedir} is expanded in "$(prefix)/include" and not "/toto/include" Definitely, I don't catch unix scripts... Thanks for your graceful help Best regards >I try to do the following in my configure.ac : > >AC_SUBST([test_xidml_url_file_1],$abs_builddir/test/run-time/xx.xidml) >I get only /test/run-time/xx.xidml in my var after substitution.. > >I've put some debug echo in my configure : > echo abs_builddir=$abs_builddir >I get abs_builddir= > >In another .in file, I used toto=@abs_builddir@, and It worked, toto was not empty > >What do I miss ? >Can somebody explain me why these variables are not set ? > >Thank you _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
