For debugging purposes, I would like to have the value of the current build's svn revision in the source code. I have written a macro to do this, however, I cannot get the value of $(SVN_REV) into config.h. I was previously able to get $(datadir) into my makefiles through the following method: CXXFLAGS="$CXXFLAGS -DWHEREAMI=\\\"\$(datadir)\\\"" However, I have found no equivalent for my current problem. I have tried to mimic the code for AC_DEFINE_DIR, but I am not sure what the following lines do (actually, the entire macro is somewhat of a mystery!): eval ac_define_dir="\"[$]$2\"" eval ac_define_dir="\"$ac_define_dir\"" Thanks, Brian _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
