unable to compile

Hello,

I have the following error when compiling defendguin:

make
make: sdl-config: Command not found
make: sdl-config: Command not found
cc -Wall -DDATA_PREFIX="/usr/local/share/defendguin/" -D__SOUND -DJOY_YES src/defendguin.c -c -o obj/defendguin.o
src/defendguin.c:25:17: fatal error: SDL.h: No such file or directory
#include <SDL.h>
^
compilation terminated.
make: *** [obj/defendguin.o] Error 1

I have libSDL packages installed

Opensuse 13.1 64bit os

look (install) for your developer headers, libSDL-dev or libSDL-devel or how ever your distro names them.

YesItsMe · 12-02-2018, 07:53 AM

On openSUSE, it's libSDL-devel.

BW-userx · 12-02-2018, 02:39 PM

yes, most distros make it whatever they want.

Thanks, I solved that problem, now the compiler complains about not finding SDL_mixer.h

make
cc -Wall -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -DDATA_PREFIX="/usr/local/share/defendguin/" -D__SOUND -DJOY_YES src/defendguin.c -c -o obj/defendguin.o
src/defendguin.c:28:23: fatal error: SDL_mixer.h: No such file or directory
#include <SDL_mixer.h>
^
compilation terminated.
make: *** [obj/defendguin.o] Error 1

here is something on your distro and this issue?

After searching my system, I have libsdl_mixer-1_2-0 installed, however, I can not find it. I have what appears to be all the sdl and sdl mixer files. The sdl folder I can find, but I can not find the mixer folder or the sdl mixer header file. If libsdl_mixer is listed, then it is installed. How do I include the mixer when doing the compile?

What application are you trying to compile?

That page I linked suggest using

Code:

pkg-config --cflags SDL2

so it might be something like 
g++ file.c pkg-config --cflags SDL2 -o app name

adding what else you use in that line as well. what is your make file?

sirius57 · 12-16-2018, 07:03 PM

If I understand what the code in your post refers to, that I have to associate the compiler with the mixer? I am trying to compile Defendguin.
Listed below is the make file:

let me run that on my system as see if I can figire it out for you.

I just issued 'make' bamn done.

you installed you SDL devel here
https://software.opensuse.org/package/libSDL-1_2-0

do a find for the files it says it cannot find,

Code:

find / -type f -iname xxx

using iname for no case senitive search, if you cannot find them, then do a wild card search for the files, they maybe under a name that is not exectly like it is looking for. If so, then just hack your code to make them match what you have on your system. that is what I'd do.

It is only one c file in your source to modify.

Code:

#include <SDL.h>

#ifndef NOSOUND
#include <SDL_mixer.h>
#endif /* #ifndef NOSOUND */

in the doc/INSTALL.txt

Code:

Note: If you do not have the SDL_mixer library, or wish to not
    compile sound support into the game, you can compile it like this:

        make nosound

I suggest you read INSTALL.txt and README.txt

glad if you manage to compile it!
but i just wanted to mention that the last time this package received any sort of update was 2009. a LOT has changed since then. compilers, libraries...
there's also a precompiled version, maybe it works?
