Windows Setup - Codeblocks - Samples Don't - reference error

[sfmlBlue]

Newbie,

I followed the tutorial and got the 'timer' code to compile and run without problems.  I set the search directories for the compiler and linker, set the extra linker command line options and created a directory for the dll files and set the windows path to pick it up.

When I try to load and run one of the sample problems I get lots of 'undefined reference' errors.  Is there any other reason for this, am I missing something?

Julio.

If you are linking with the dynamic library(those without -s in their names), you must define SFML_DYNAMIC . If you're linking with the static libraries, make sure you didn't define it by accident.

I'm having a similar problem.
I can use any SFML resource in the dynamic way, with the dlls. No problems at all.
But I still can't build a project with static linking (get lots of undefined reference errors), except for tasks like the clock and the sound examples.

I though it's related to the external libs.. I don't know

Here's the build log when building the window.cbp example (the example that gives less errors)

I'm not familiar with gcc, but from the error, I think you did not link with the standard c++ library.

[Wizzard]

Do not link against libsfml-main-d.a when compiling the SFML statically.

Also, you don't need to link against the GLU or OpenGL in the SFML, although you might need to if you use them directly.

I'm not familiar with gcc, but from the error, I think you did not link with the standard c++ library.

GCC doesn't link against libraries for standards.

hm, this time a little more clear, a minimal code:

Code: [Select]

#include <SFML/Window.hpp>
int main(){
    sf::Window app(sf::VideoMode(640, 480, 32), "SFML Window");
    while (true) app.Display();
}

the start of the build log:

Code: [Select]

mingw32-g++.exe -Wall  -g  -Wall   -IC:\...\SFML-1.3\include  -c "C:\...\main.cpp" -o obj\Debug\main.o
mingw32-g++.exe -LC:\...\SFML-1.3\lib\mingw  -o bin\Debug\clock.exe obj\Debug\main.o   -lsfml-window-s-d -lsfml-system-s-d  

C:\...\SFML-1.3\lib\mingw/libsfml-window-s-d.a(WindowImpl.o)(.text$_ZNSt23_Rb_tree_const_iteratorIPN2sf14WindowListenerEEppEv+0x13):WindowImpl.cpp: undefined reference to `std::_Rb_tree_increment(std::_Rb_tree_node_base const*)'
(and more 5 like this one)

Same for non debug static link. I don't know what's missing. I think I did everything as the tutorial says

It looks like your GCC install is messed up. Perhaps you overwrote some standard include files?

Are you still able to compile non-SFML projects OK (especially those using the STL)?

[gsaurus]

Yes, it compiles other projects that uses the STL
eh, I'll reinstall GCC and see if it works

Edit: ups! Reinstalled and it It works now!! :shock: Thanks for the tip , I was loosing my time
