[Linux] SFML 2.0 won't link properly

[cgonz905]

I'm trying to run the tutorial sample code from here: http://www.sfml-dev.org/tutorials/2.0/start-linux.php
It compiles successfully, but when I run:

 g++ main.o -o app -lsfml-graphics -lsfml-window -lsfml-system

I get these errors:

/usr/bin/ld: warning: libjpeg.so.62, needed by /usr/lib/gcc/x86_64-linux-gnu/4.6/libsfml-graphics.so, not found (try using -rpath or -rpath-link)

Can someone please help me get this working? Thank you so much in advance.

You miss the jpeg library (see here for the full dependency list).
You should be able to grab it from your distros package manager.

[cgonz905]

I installed "libjpeg-dev" and I keep getting the same errors. Is that the wrong package?

[eXpl0it3r]

So from where did you get SFML? Have you built it yourself?
If not, then the versions might not be the same. Which version of libjpeg-dev have you installed?

[cgonz905]

I install SFML via apt-get (sudo apt-get install libsfml-dev) and JPEG via apt-get (sudo apt-get install libjpeg-dev)

I'm not entirely sure what versions, but that's what I did.

[eXpl0it3r]

From the command I guess you're on a Debian like distro and from what I know, none of them have already update their packages to SFML 2, so you essentially end up with SFML 1.6.
You should either get the binary from the download page or even better build SFML yourself.

[cgonz905]

I took your advice and I downloaded the SDK instead. I placed the lib, include and share folders inside of usr/local. After doing that, I compiled the sample program successfully but I ran into the same errors when I tried linking.

[eXpl0it3r]

Make sure to uninstall the libsfml-dev package, otherwise the compiler *might* use the old libs.
Also make sure to do a clean build.

[cgonz905]

I fixed the problem. I ended up switching OSes anyways, so I had a clean install of everything. So in Lubuntu 13.04 I simply downloaded SFML 2.0 then compiled with:
 

g++ main.o -o sfml-app -L<sfml-install-path>/lib -lsfml-graphics -lsfml-window -lsfml-system

And I installed the JPEG library via "sudo apt-get install libjpeg62-dev"

But now I'm getting these errors:

I'm assuming I'm missing GLEW, but when I entered: "sudo apt-get install libglew-dev" it still doesn't work. Did I install the wrong library? Or am I totally off here?

[eXpl0it3r]

Seems like sfml-graphics was built with GLEW 1.5 and your OS probably uses a newer version.
You've now the option to build SFML new or get the 1.5 version (if that's possible).
I suggest to build SFML newly, just because, you'll then know that all the dependencies match.

If I'm gonna build from source, I have to install all the dependencies. But I can't find the xlib dependency. After "apt-cache search libxlib" I get these results:

Which library is it? It seems like it could be any one of them.

libx11-dev

libx11-dev

Thank you! One last questions. I built SFML 2.0 via cmake and everything compiles and links correctly with the test "main.cpp", my only problem is when I run it the app, I have to run via "export LD_LIBRARY_PATH=<sfml-install-path>/lib && ./sfml-app"

How do I solve this problem? I compiled and linked without having to specify which directory the "SFML Build" was located, but I do when it comes to running the app? I also compiled SFML (The library, not the app) via "make all" then "make install" if that helps at all.

Any ideas?

[Laurent]

This is because the library loader (ld) doesn't know <sfml-install-path>/lib. You should search on Google the way to add a path permanently to ld (I never remember ).

Oh, silly mistake on my end. Turns out once you run:  "export LD_LIBRARY_PATH=<sfml-install-path>/lib" you only have to do that once. So I'm okay now. Thank you all for your help!
