Can't get SFML working :(

[lazeriux]

I guess I linked bad build commands or I installed sfml bad.

I just dropped sfml files to usr/local

compilation errors:

Instead of posting these problems again and again, you should really take the time to read the tutorial carefully.

To link a SFML library, you must add "-lsfml-xxx" to your command line, for example "-lsfml-graphics" for the graphics module

[Laurent]

I just dropped sfml files to usr/local

g++ -Wall -o "omg" "omg.cpp" -Isfml/include -Lsfml/lib

You didn't realize that "sfml/include" and "sfml/lib" are supposed to be real paths to your SFML include and lib directories... right?

If you're a beginner, you should really take some time to learn how to use your programming tools before starting to use a library such as SFML. We can help you to solve your problems, but we can't teach you everything on this forum.

[lazeriux]

g++ -Wall -o "%e" "%f" -usr/local/Lsfml/include -usr/local/Lsfml/lib

same errors

[Laurent]

Now read (and apply) Nexus' reply

I insist, you should really try to understand what you do, what all these command line options mean. It's basic stuff, you'll have to do the same for any other library that you want to use -- and some of them are more complicated to use than SFML.

[lazeriux]

I still don't understand what to write there :/

[Laurent]

I doubt you've read the tutorial, because it gives the exact command lines that you need to write. You just have to copy and paste, even if you don't understand everything.

[Laurent]

As I said in the other thread, if you installed SFML in a non-standard path, you must modify your LD_LIBRARY_PATH environment variable so that the library loader can find SFML libraries at runtime (Google it if you don't know what to do exactly).

[lazeriux]

Now errors is:

./omg: error while loading shared libraries: libGLEW.so.1.5: cannot open shared object file: No such file or directory

[Laurent]

Do you have GLEW installed? Which version?

It's strange that it's asking for 1.5, as far as I remember, SFML was compiled with at least GLEW 1.7.

[lazeriux]

2.0

[Laurent]

The latest GLEW is 1.9.0...
