Yes, we discussed this topic in the thread started in <http://lists.gnu.org/archive/html/bug-gnulib/2007-04/msg00232.html>. I had been pointing you to gettext/gettext-tools/libgettextpo/Makefile.am; nowadays the same technique is also used in libunistring/lib/Makefile.am. In particular, look at this commit: http://git.savannah.gnu.org/gitweb/?p=libunistring.git;a=commitdiff;h=d598f9e1e016735397e9dca53b436d13c6fb28f3 > Should `gnulib-tool --import' create AC_DEFINE's to map each global > gnulib function symbol into some application provided namespace? > E.g. `gnulib-tool --import --symbol-prefix _gnutls'? This would then > create something like this: > > AC_DEFINE([read_file], [__gnutls_read_file]) > > Maintaining the list of global gnulib functions will be a hassle > though. Could this be automated? Possibly. In the cases I needed, I did not have to hide all global symbols coming from gnulib, but only some of them. I don't know whether in the case you mention things get simple enough that gnulib could generate the redirections in config.h. Bruno
