Errors while linking
« on: January 23, 2011, 10:57:04 pm »
i am brand new to this SDK and i just tried compiling the test code from the tutorial that uses the clock.

when i compiled it i received 4 errors.  every single error was  LNK2019.

i followed the installation instructions perfectly.

i am using the Visual C++ 2008 to compile and i am running it on a windows XP, 32 bit.

any way to fix this?

We're not compilers, it's easier to understand with the message than with the code... ;)

Looks like you didn't link to SFML (or at least parts of it). What are your linker settings for each configuration?

In SFML 1, you also have to define the macro SFML_DYNAMIC when linking dynamically.
In SFML 2, it's just converse (SFML_STATIC for static linking required).

There's no OpenGL SDK, you already have all the GL libraries. Here you need opengl32.lib and glu32.lib.
