Background: Android's linker has some bugg^Wunusual behavior, in that it caches loaded libraries, but only uses the basename in the cache. That means that, as far as its dlopen() is concerned, the libraries for Hash::Util and List::Util, both of which are named Util.so, are the same. What we did in the android branch was introduce an option, d_libname_unique, that when defined, has Makemaker create an "unique" libname for each module, and teaches XSLoader and Dynaloader to look for those; So for example, Hash/Util/Util.so becomes Hash/Util/Perl_Hash_Util.so. The changes for this are in http://perl5.git.perl.org/perl.git/shortlog/refs/heads/hugmeir/d_libname_uniqueand can be tested by compiling perl with -Dd_libname_unique. Any objections to this going in?Thread Next
