I just can't understand this. The code works perfectly on the emulator(Which is supposed to give more problems than phones…), but when I try it on a LG-E610 it doesn't compile the vertex shader. This is my log error(Which contains the shader code as well):
EDITED
Shader:
uniform mat4 u_Matrix;
uniform int u_XSpritePos;
uniform int u_YSpritePos;
uniform float u_XDisplacement;
uniform float u_YDisplacement;
attribute vec4 a_Position;
attribute vec2 a_TextureCoordinates;
varying vec2 v_TextureCoordinates;
void main(){
v_TextureCoordinates.x= (a_TextureCoordinates.x + u_XSpritePos) * u_XDisplacement;
v_TextureCoordinates.y= (a_TextureCoordinates.y + u_YSpritePos) * u_YDisplacement;
gl_Position = u_Matrix * a_Position;
}
Log reports this before loading/compiling shader:

Maybe it has something to do with that men alloc? The phone is also giving a constant error while plugged: ERROR FBIOGET_ESDCHECKLOOP fail, from msm7627a.gralloc
Edited: "InfoLog:" refers to glGetShaderInfoLog, and it's returning nothing. Since I removed the log in a previous edit I will just say i'm looking for feedback on compiling shaders.
Solution + More questions: Ok, the problem seems to be that either ints are not working(generally speaking) or that you can't mix floats with ints. That brings to me the question, why on earth glGetShaderInfoLog is returning nothing? Shouldn't it tell me something is wrong on those lines? It surely does when I misspell something.
I solved by turning everything into floats, but If someone can add some light into this, It would be appreciated. Thanks.
