help compiling a program

hello, i just installed SDL 1.2 (and the devel packages) which is needed to get zsnes working. However, when i go to compile zsnes, i get this error:

Quote:

checking for SDL - version >= 1.2.0... no
*** Could not run SDL test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding SDL or finding the wrong
*** version of SDL. If it is not finding SDL, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location Also, make sure you have run ldconfig if that

*** If you have an old version installed, it is best to remove it, although
*** you may also be able to get things to work by modifying LD_LIBRARY_PATH
configure: error: SDL >= 1.2.0 is required

I have never gotten this error before i don't quite understand what i have to do.. Can somebody give me step by step instructions on how to make it show that SDL is indeed installed?

I installed sdl and sdl-devel using rpm packages which is on their site.

Thanks!

First thing to do is try what the message suggests

Quote:

*** is required on your system

As root, run ldconfig. If you'd like to be 100% positive the library is included, then execute this command:

Code:

$ ldconfig -v | grep libSDL

That command should give you at least one line of output. On my system, it gives:

Code:

        libSDL-1.2.so.0 -> libSDL.so

If you do not get anything, then the SDL library is not in one of the expected locations.

If you get some output like I have quoted above, try recompiling.

If you don't get any output or the recompile still doesn't work, then we can look at other possible reasons.

hey, thanks for the reply!
i tried what you said and i got this:

mark@linux:~> ldconfig -v | grep libSDL
bash: ldconfig: command not found

however, i'd like to note that i solved the problem. The solution was in another thread. Here it is:
