Hello, me again with another newbie question!
I have tried to download several games to play on my linux box and when I attempt to
./configure them I get this output ALOT:

checking for SDL - version >= 1.2.5... no
*** The sdl-config script installed by SDL could not be found
*** If SDL was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the SDL_CONFIG environment variable to the
*** full path to sdl-config.
configure: error: *** SDL version 1.2.5 not found!

I attempted to download SDL and install it but it says something about it already being on my machine. Any help would be appreciated!

THX,
TC

did you download the development headers? you probably only have the sdl binary libs. you can get the development headers by downloading, compiling, and installing the SDL source.

hello..
I'm newbie in SDL..

i always get this error while compiling my sdl aps...

im using SDL-1.2.6 and SDL-Devel-1.2.6

I've setup the Linker Options like the Mini-Howto told..

(i'm using KDevelope)..

is there anyway to setup SDL in KDevelope ??

and how to solve this problem..


thanks in advance..

btw.. this is my source code :
#include "SDL/SDL.h"
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{

printf("SDL initialized");
if(SDL_Init(SDL_INIT_VIDEO | SDL_INIT_TIMER)){
printf("SDL Initialized Successfully ");
}
else
{
printf("inisialisasi gagal ");

}
SDL_Quit();
return EXIT_SUCCESS;
}

maybe you should downgrade to SDL-1.2.5?

well.. I'll try that one...

but after I posted my problem here..
I downloaded sdl-config from libsdl.org respistory (* ups bad english)
then I tried to recompiled...

then the error is changed :
gmake all-recursive
gmake[1]: Entering directory `/home/duffy/sdlc'
cd . && /bin/sh ./config.status Makefile

notice this :

Uhh. Malformed pattern in .subs (s,@LDFLAGS@,-I/usr/include/SDL -D_REENTRANT) at admin/config.pl line 97.

am i got the wrong sdl-config ??

and this :
/home/duffy/sdlc/sdlc/main.c:27: undefined reference to `SDL_Init'

damn.. I've checked that all linker and directories is set...

ok.. then I tried to downgrade the SDL to 1.2.5
but it didn't work

still the same error

ahhh... at last...
I found the answer...

here what I did for this SDL work on my KDevelope..

oh yeah.. for more information.. i'm using SuSE 9.0

first..
in Compiler Options.. add this in Linker Flags :
-L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -I/usr/include/SDL -D_REENTRANT

then check if slang library is installed on your system...
I've checked mine.. and it was an error like it cannot found -islang flags etc.. ( I dont understnad this... :P heheh I'm a Newbie anyway..)

then.. I tried to install slang-devel from the SUSE 9.0 Distribution CD
then... I tried to compile my program again...

walah... Its worked smoothly

hope this information will be usefull for a newbie like me who stuck like I was

thanks for your responses guys

Try this...
g++ -Wall `sdl-config --cflags` `sdl-config --libs` -o example example.c
