If a #version directive does not appear at the top, then it assumes 1.10, which is almost certainly not what you want.Įvery OpenGL version since 2.0 has been released with a corresponding GLSL version. The #version directive must appear before anything else in a shader, save for whitespace and comments. If a profile name is not specified, the default is core. The version number can be followed by the profile name. ![]() ![]() This would tell the compiler to compile for version 1.50, or error if that version is not available. To specify which version of GLSL should be used to compile/link a shader, use this directive: As part of the OpenGL Specification, each version of OpenGL is required to support specific versions of GLSL it may optionally support more. The OpenGL Shading Language has gone through a number of revisions, some of them quite substantial. If you want to globally apply these, then you should put them in a string that is first in the array of strings passed to the shader object with glShaderSource, or to glCreateShaderProgram. These should be in the first lines of the first string associated with a shader object. GLSL's compilation model instead requires them to be part of the language. In a command-line-based compiler, these would be command-line compiler options. The OpenGL Shading Language requires certain information to be presented early in a shader object's compilation. ![]()
