Using the -i option, you can generate the intermediate tree (glslang AST, AST is the not structured flow control representation of the GLSL shader). GLSL Version: 4.20 glslang LunarG Khronos.24740 1 12:29:55Īccording to the documentation, the current version of glslangValidator supports GLSL shaders up to GLSL #version 1.40 / OpenGL 3.1 (so why it tells that version 140 is not yet complete? Is it related to the machine I currently use to write this new?). The current version of glslangValidator can be checked withĮSSL Version: OpenGL ES GLSL 3.00 glslang LunarG Khronos.24740 1 12:29:55 Now if I remove the at the line 11, here is the output:ĮRROR: 1 compilation errors. Warning, version 140 is not yet complete most features are present, but a few are missing. To validate this vertex shader (file vs.vert), just use type this command: Vec4 eye = gxl3d_ModelViewMatrix * gxl3d_Position Gl_Position = gxl3d_ModelViewProjectionMatrix * gxl3d_Position Uniform mat4 gxl3d_ModelViewProjectionMatrix I quickly tested glslLangValidator with the following GLSL 1.40 (OpenGL 3.1) vertex shader took from GLSL Hacker code sample pack. You can download the command line version from HERE. ![]() More information about can be found here: OpenGL / OpenGL ES Reference Compiler. It is open and free for anyone to use, either from a command line or programmatically. ![]() It implements a strict interpretation of the specifications for these languages. glslLangValidator is the official reference compiler front end for both OpenGL ES and OpenGL shading languages. GlslLangValidator is GLSL tool for Windows / Linux released by the Khronos Group.
