Is libsdl1.2 badly linked?
Hi!
I've been having problems with some programs that used to link well to
libsdl but that now don't, when I looked at libsdl I found that it has many
symbols that are not defined, I really believe that this is a bug, but I'd
like to know more opinions. This was a silly test I made that demonstrates
the symbols that libsdl1.2 is missing and where they come from:
mantinan@pul:~$ cat >hello.c <<END
> #include <stdio.h>
> int main (int argc, char **argv)
> {
> printf ("Hello, world!\n");
> return 0;
> }
> END
mantinan@pul:~$ gcc hello.c -lSDL -lpthread /usr/X11R6/lib/libXxf86dga.a
/usr/X11R6/lib/libXxf86vm.a /usr/X11R6/lib/libXv.a -o hello
mantinan@pul:~$ gcc hello.c -lSDL -o hello
