failing shader
Patch to the mentioned shader |
||
Looks like a shader bug, there's no implicit conversion in GLSL (at least the lower versions). No doubt Nvidia would let this shader through ;) The attached changes make it build on Mesa. Created attachment 47858 [details] [review] Patch to the mentioned shader Right. Alternatively, they could just switch to GLSL 1.20 (#version 120), which adds implicit conversions. It's just 1.10 which is so picky. At some point, we may need to add some kind of "relaxed" mode to our compiler, but I'd like to avoid it as long as possible. We're actually compliant here. Closing as NOTOURBUG. I've attempted to contact the developers of Galactic Vice---hopefully they'll be willing to fix the shaders for their next alpha release. Thanks for the help! Turns out the game also needs a few other features, at least GL_EXT_gpu_shader4 and GL_EXT_texture_array but it's a step in the right direction! |

Created attachment 47849 [details] failing shader The game Galactic Vice fails to run with Mesa, one of the shaders fails to compile with the following errors: 0:10(54): error: Could not implicitly convert operands to arithmetic operator 0:10(55): error: Operands to arithmetic operators must be numeric 0:10(32): error: cannot construct `vec2' from a non-numeric data type 0:0(0): error: no matching function for call to `texture2D(sampler2D, )' 0:0(0): error: candidates are: vec4 texture2D(sampler2D, vec2) 0:0(0): error: vec4 texture2D(sampler2D, vec2, float) 0:10(63): error: Operands to arithmetic operators must be numeric 0:10(63): error: type mismatch 0:13(32): error: Could not implicitly convert operands to arithmetic operator 0:13(32): error: type mismatch The requirements for the game does mention OpenGL 3, so I'm not sure if this is a bug in the shader compiler or not, but filing a bug just to be sure.
