Maybe this is because of the old hardware but there are two issues when compiling the fragment shader on linux:
float textSlot to inttexSlot is not properly converted to an integer. Here is an ugly workaround:
#version 330 core
in vec2 texCoord;
in vec4 spriteColor;
in float texSlot;
uniform sampler2D u_Textures[32];
out vec4 fragColor;
void main()
{
switch(int(texSlot))
{
case 0: fragColor = spriteColor * texture(u_Textures[0], texCoord); break;
case 1: fragColor = spriteColor * texture(u_Textures[1], texCoord); break;
case 2: fragColor = spriteColor * texture(u_Textures[2], texCoord); break;
case 3: fragColor = spriteColor * texture(u_Textures[3], texCoord); break;
case 4: fragColor = spriteColor * texture(u_Textures[4], texCoord); break;
case 5: fragColor = spriteColor * texture(u_Textures[5], texCoord); break;
case 6: fragColor = spriteColor * texture(u_Textures[6], texCoord); break;
case 7: fragColor = spriteColor * texture(u_Textures[7], texCoord); break;
case 8: fragColor = spriteColor * texture(u_Textures[8], texCoord); break;
case 9: fragColor = spriteColor * texture(u_Textures[9], texCoord); break;
case 10: fragColor = spriteColor * texture(u_Textures[10], texCoord); break;
case 11: fragColor = spriteColor * texture(u_Textures[11], texCoord); break;
case 12: fragColor = spriteColor * texture(u_Textures[12], texCoord); break;
case 13: fragColor = spriteColor * texture(u_Textures[13], texCoord); break;
case 14: fragColor = spriteColor * texture(u_Textures[14], texCoord); break;
case 15: fragColor = spriteColor * texture(u_Textures[15], texCoord); break;
case 16: fragColor = spriteColor * texture(u_Textures[16], texCoord); break;
case 17: fragColor = spriteColor * texture(u_Textures[17], texCoord); break;
case 18: fragColor = spriteColor * texture(u_Textures[18], texCoord); break;
case 19: fragColor = spriteColor * texture(u_Textures[19], texCoord); break;
case 20: fragColor = spriteColor * texture(u_Textures[20], texCoord); break;
case 21: fragColor = spriteColor * texture(u_Textures[21], texCoord); break;
case 22: fragColor = spriteColor * texture(u_Textures[22], texCoord); break;
case 23: fragColor = spriteColor * texture(u_Textures[23], texCoord); break;
case 24: fragColor = spriteColor * texture(u_Textures[24], texCoord); break;
case 25: fragColor = spriteColor * texture(u_Textures[25], texCoord); break;
case 26: fragColor = spriteColor * texture(u_Textures[26], texCoord); break;
case 27: fragColor = spriteColor * texture(u_Textures[27], texCoord); break;
case 28: fragColor = spriteColor * texture(u_Textures[28], texCoord); break;
case 29: fragColor = spriteColor * texture(u_Textures[29], texCoord); break;
case 30: fragColor = spriteColor * texture(u_Textures[30], texCoord); break;
case 31: fragColor = spriteColor * texture(u_Textures[31], texCoord); break;
}
}Hardware max texture slots is 16. The fact that we're creating a uniform sampler2D u_Textures[32]; makes the compilation to fail.
Either we need to make a separated shader for Linux with a limited number of textures slots (and limit it in the Painter as well). Or find a workaround.
There is a linking error when compiling a project using Fluffy as external dynamic library.
It may come from the template implementation
While fetching an EntityComponentView from EntityManager::each() but there is no entity to fetch for the given components, it seems that the code is able to iterate on the View regardless. Leading to errors because of invalid entities.
