Working on support for -flto has uncovered an ugly buglet in libltdl. ltmain declares this symbol as:extern $lt_dlsym_const lt_dlsymlist lt_${my_prefix}_LTX_preloaded_symbols[]; but libltdl declares it as: #define preloaded_symbols LT_CONC3(lt_, LTDLOPEN, _LTX_preloaded_symbols) #ifdef HAVE_LIBDLLOADER extern lt_dlsymlist preloaded_symbols; #endif (note the missing []) and takes its address to make up for it. gcc -flto notices this inconsistency between the objects. This patch fixes it, it passes the testsuite. I'll be pushing it soon. I don't actually know whether this bug can cause issues on some system.
Nice catch. I had not been aware of the -flto option before. Bob -- Bob Friesenhahn [email protected], http://www.simplesystems.org/users/bfriesen/ GraphicsMagick Maintainer, http://www.GraphicsMagick.org/
