uniform,attribute type error ?

[kakashi]

hi,

im using SDL2, NDK, OpenGl ES 2.0 on ubunto 12.04, and when i declare variable as "uniform type or attribute type", i get this error :

main.cpp:15:1: error: 'uniform' does not name a type

here my included files :
#include <SDL2/SDL.h>
#include <android/log.h>
#include <iostream>
#include <GLES2/gl2.h>
#include <EGL/egl.h>
#include <GLES2/gl2ext.h>

thanks a lot.

And what do you have at line 15 of main.cpp?

thank you thokra for your reply

[carsten neumann]

Please use [code][/code] tags around source code.
You are programming in C/C++ and "uniform" is not a keyword in those languages, hence the compiler complains. It is a keyword in GLSL, but code written in GLSL is stored in strings (or loaded at runtime from text files) and passed to the shader compiler (at runtime!) that is part of your OpenGL implementation (aka. the graphics driver).

sorry its my first post, and thank you its clear
