You will want to use $build instead of $target > but it works. If the only purpose is to access the toplevel source directory inside of configure, all this is superfluous. You can simply use $srcdir inside of configure.ac instead. If the purpose is to propagate the toplevel directory to files in subdirs through AC_SUBST, using abs_*dir's render configured build-trees to be non-relocatable (Consider logging in into the same account from different nfs-mount-points, say /nfs/<machine>/<account>) If the purpose is to access files inside of the source-tree from inside of Makefile.am, there are better ways of doing so (using relative paths, being composed of $(subdir) and $(top_srcdir)) You are probably using an antiquated autoconf. Modern autoconf's already support abs_top_srcdir and abs_top_builddir.
