Fix dlvsym() detection in the configure script. --ryan. From: Mike Frysinger <vapier@gentoo.org> To: sdl@libsdl.org Subject: Re: [SDL] sdl, sdl-mixer not compiling with uclibc Date: Wed, 7 Sep 2005 19:17:49 -0400 in this case actually, the error is in libsdl the configure check for dlvsym presence is pretty pointless, it currently always detects it AC_TRY_COMPILE([ #include <stdio.h> #define __USE_GNU #include <dlfcn.h> ],[ dlvsym(NULL,"",""); ],[ use_dlvsym=yes ]) since it's merely compiling, the warning about dlvsym being implicitly declared doesnt trigger a failure find attached a patch to fix this -mike
