GUI compile problems (fwd)

[Bill_Kendrick]

Hi folks, Sam said I should bug you regarding problems compiling the
GUI example. I’ve installed SDL 0.9.9.

I’m running Linux 2.0.36 on a P133. Thanks!

You might ask the SDL mailing list. I remember people having the problem
and fixing it, but I don’t remember the solution.

cc -o hello hello.o -L. -lGUI -lpthread -L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -ldl

It looks like part of this was compiled with egcs, but you’re using an older
gcc. Are you using pre-compiled SDL libs?

Nope! I just built 0.9.9 from scratch. I double-checked to see if any of
/usr/local/lib/libSDL* are old, but it’s all from this morning… <:^/

I already had this problem but I forgot how I had resolved it
but now you know it CAN be resolved.
Have you checked the GNUmake file ?
Have you inserted it ?
Is /usr/local/lib in your ldpath ?
if not, try a ldconfig with some option I don’t remember,

Good luck

I had this happen to me a couple of times too … I don’t remember what I did
about it either, BUT I seem to recall that it came down to something about the
linker not mixing C and C++ objs and libs. I remember that in debugging it if
I turned all of my C sources into CPP sources (which sucked!) the problem went
away. YMMV.

I already had this problem but I forgot how I had resolved it
but now you know it CAN be resolved.

Umm… checked it for what? (I hate to sound dumb, but… I am )

Have you inserted it ?

???!

Is /usr/local/lib in your ldpath ?

Should be. The “gui” makefile references “-L. -lGUI”, so it’s using
"libGUI.a" in the “gui” directory. Just in case, I did copy the .a file
to /usr/local/lib.

if not, try a ldconfig with some option I don’t remember,

Heheh. I certainly don’t know what the option is, either.

Does anyone else have any ideas?

I’m using “GUILIB Copyright 1997 Sam Lantinga”.
“make” builds everything without error.
“make hello” and “make hello_C” both return similar errors:

25/home/kendrick/SDL/SDL-demos/gui>make hello_C
cc -o hello_C hello_C.o -L. -lGUI -lpthread -L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -ldl

make: *** [hello_C] Error 1

I know NOTHING about C++, so, after not finding any references to,
for example, “terminate”, in any of the sources, I assume this is just
some funkiness on my end. (Although it sounds like others have had annoying
problems, too.)

I’m using:

• Linux version 2.0.36 (root at porky.redhat.com) (gcc version 2.7.2.3) #1
  Tue Oct 13 22:17:11 EDT 1998
• cc version 2.7.2.3 (looks to be a symb. link to gcc)
• c++ and g++ both claim: “egcs-2.90.29 980515 (egcs-1.0.3 release)”
  (not a symbolic link for some reason, though… just two duplicate(?)
  binaries)
• SDL 0.9.10

It’s not like this is amazingly important, but, I’m interested in seeing
this library, and pretty much all of the other examples I’ve tried compile
and run just fine.

Thanks!!!

“make” builds everything without error.
“make hello” and “make hello_C” both return similar errors:

Do you need to link with libstdc++ ? -lgcc? Something?

Bada-bing, bada-boom! It worked! (And I learned something. Let’s see

Thanks Sam!

Which worked? -lstdc++ or -lgcc?

Oops, frankly I dunno… I used both, both times. Let me see…

-lgcc did nothing (same errors). Not surprisingly, “-lstdc++” helped
(it compiled). This is for both “hello” and “hello_C”.
