Error loading shared library libSDL-1.2

Question

I've tired to compile ToME 3 game but I can't run it, I've got:

tome3: error while loading shared libraries: libSDL-1.2.so.0: cannot open shared
object file: No such file or directory

I have installed libstd1.2 both devel and runtime packages. I have that library

$ ls /usr/lib/x86_64-linux-gnu/libSDL*
/usr/lib/x86_64-linux-gnu/libSDL-1.2.so.0
/usr/lib/x86_64-linux-gnu/libSDL-1.2.so.0.11.4
/usr/lib/x86_64-linux-gnu/libSDL.a
/usr/lib/x86_64-linux-gnu/libSDL_image-1.2.so.0
/usr/lib/x86_64-linux-gnu/libSDL_image-1.2.so.0.8.4
/usr/lib/x86_64-linux-gnu/libSDLmain.a
/usr/lib/x86_64-linux-gnu/libSDL.so

I've tried to put /usr/lib/x86_64-linux-gnu/ into PATH and also copy libSDL-1.2.so.0 to the directory where I have the game, but it not work.

Someone ask the same question on AskUbuntu the solution was to reinstall the lib but it don't work.

Solution

Run ldd on the game's binary (t-engine) to see what exactly it's looking for and whether it resolves.

See the paths that are searched and what is found by using strace -e file t-engine. If you see some paths being searched for libSDL but not the path where your libSDL is (/usr/lib/x86_64-linux-gnu/), then see if you can figure out why.

My guess is that t-engine is compiled for i386 (32-bit) and your SDL libraries are compiled for x86_64 (64-bit).

I have libSDL-1.2.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libSDL-1.2.so.0 entry. When you install lib using apt-get it run ldconfig automatically.

[Tim]

It show libSDL-1.2.so.0 => not found; libSDL_net-1.2.so.0 => not found; libSDL_mixer-1.2.so.0 => not found but all other point to files in /usr/lib/i386-linux-gnu

How to compile it using 64bit?

[RJHunter]

That's specific to the game you compiled -- usually a ./configure script will auto-detect which platform (or will use your compiler's default). Check the game documentation.

[RJHunter]

If the game is 32-bit only, you can just install the 32-bit versions of the SDL libraries, using something like apt-get install libsdl1.2:i386

that file wasn't there, so I need to install sudo apt-get install libsdl1.2-dev:i386 libglu1-mesa-dev:i386 libglu-dev:i386 bump into this: bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1296474 then also install libsdl-mixer1.2-dev:i386 and libsdl-net1.2-dev:i386 to make it work.
