But that would require extra Makefile.am rules that the developer has to write. The --enable-relocatable mechanism tries hard to get away with minimal changes to the Makefile.am: <http://www.gnu.org/software/gnulib/manual/html_node/Supporting-Relocation.html> Therefore I would suggest to solve this problem by adding #undefs in specific places, such as /* Use the system functions, not the gnulib overrides in this file. */ #undef fprintf #undef sprintf What is the complete required symbol list (nm ...o | grep ' U ') of the set of modules compiled for the relocwrapper on your system? > Another way would be to make the substitutions conditional on > !IN_RELOCWRAPPER, but that seems fragile Yes, this would be fragile. But maybe we need this approach for the set_relocation_prefix functions. Bruno
