Title: Problem compiling SFML 2.0 program
Post by: aeron on February 03, 2011, 11:28:24 pm

I followed the instructions to build SFML 2.0 with CMake and it seemed to work without a problem. So now I try to compile against the library but I keep getting errors:

Code: [Select]

So yeah, what might cause this? The program is trivially simple, it's just a basic game loop at the moment. I have the compiler/linker search directories set correctly and everything, and I'm using the exact same compiler I used to compile SFML (TDM-GCC). Using SVN revision 1786

Are you linking statically?

Yes.

Edit: Strangely enough, compiling against the dynamic libraries works just fine.

Not strangely. Static linking requires the SFML_STATIC preprocessor macro to be defined.

Ah sounds familiar, but.. Did you always have to do this? I can't remember if I had to use it in 1.7 or not. Regardless, it's working great now, thanks for the help Laurent!

There isn't a 1.7. And it's new to SFML2.

The Download Page (http://www.sfml-dev.org/download.php) list the latest non SFML2 trunk as SFML 1.7

In SFML 1.x it was SFML_DYNAMIC for dynamic libraries.

SFML 1.7 will never exist, but that's how the current trunk is named, until the sfml2 branch is merged into it.

Yeah that's what I checked but I meant 1.6.

Sounds right, that's what I was thinking about.

I am trying to use your particle engine with Sfml and got some problems. I have the exact same code as in tutorial 2  and linked all right. Static SFML libraries and static libraries to IGNITE. There are no linker error, but when I try to compile it is a strange error without assistance:
