SDL App with statically linked crt

Christian_Meyer · June 4, 2010, 6:28pm

Hello!

How do I build an SDL application, which is statically linked against
the crt? I am using MS VC9 and sdl version 1.2.14.

I tried the following:

In my project settings I have set the option “Multi-threaded Debug
(/MTd)”
So I think it is necessary, to recompile SDL, so that the same
version of the crt is used, right? So I recompiled SDL and SDLmain with
"Multi-threaded (/MT)".
Compiling were successful. So I copied the SDL.dll into my project
dir and copied the .libs to the /lib directory
Then I compiled my project without any linker errors. But a warning:
“1>libcpmtd.lib(xdebug.obj) : warning LNK4098: defaultlib 'libcmt.lib’
conflicts with use of other libs; use /NODEFAULTLIB:library”
When I start my application, it crashes. The debugger shows me a line
in “void SDL_FreeWAV(Uint8 *audio_buf)”.

What am I doing wrong?

Do I have to recompile SDL_Mixer as well? I didn’t change anything on
the mixer lib. It used to work as it is. Is is necessary to recompile
SDL_Mixer when I update the SDL verison?

Thank!
Christian

If you have changed your Code Generation settings you should make them the
same for all SDL related projects you are using in your app.

So if you are now using Multi-threaded Debug (/MTd)" for your app, you
should go into each SDL related project and set it the same way, then
rebuild.

SDL, SDL_mixer, SDL_image, etc.

That will also get rid of the linker warning in #4 below.> ----- Original Message -----

Now I recompiled all SDL libs (SDL, SDL_net, SDL_Mixer). I get still the
same warning and the same crash.

Sorry, that was wrong. I am not able to compile SDL_Mixer. I get a lot
of linker errors, when I switch to “Multithreaded Debug”:

I wish I could help more. I just updated SDL to the latest from Mecurial,
then updated SDL_mixer to the latest in Mercurial

I get this error when compiling SDL_mixer:

I don’t want to link SDL statically, I want to link the crt statically,
to avoid the dependence on the msvcrt dlls.

I still was not able to compile SDL_Mixer with the option “Multithreaded

The key to getting this to compile is making sure that everything you build
has the same setting in the Code Generation section of the Project
Configuration.

So if you are using /MTd (Multi-threaded Debug) then make sure you do the
same thing for SDL, and any other projects you are building and linking
(SDL_image, SDL_ttf, etc). This also includes your own code for your
game/app.

I already recompiled all other modules, except SDL mixer. So my current
problem is to compile SDL Mixer. Independent from my own app and the
other SDL libraries.

So my question is, how can I compile SDL_Mixer with the /MTd
(Multi-threaded Debug) setting, because I get a lot of linker errors.

Christian

Christian_Meyer · June 6, 2010, 2:48pm

Now I finally got all libs compiled with the “/MTd (Multi-threaded
Debug)” Option. And now my app compiles without any linker warning.

But the crash still occurs, when the app is loading the first .ogg file.
It crashes when freeing some memory in the sdl lib, which was former
allocated by the sdl mixer lib.

Is there any way to get this running?

Thanks,
Christian
