Hi, I'm trying CodeXL to debug some OpenGL code
(D3D11 code ported to OpenGL, I'm really new to OpenGL dev)
All my shaders are compiled as GL_PROGRAM_SEPARABLE+GL_PROGRAM_BINARY_RETRIEVABLE_HINT (as on D3D), using "version 420 core" header.
(then saved as binary to avoid recompiling each time)
Using CodeXL, I delete some of the binary shaders to let CodeXL "see" the compiling process
(hoping to get more info about the shaders in the tool)
the calls to glLinkProgram raise a GLerror 0x0501
followed by glGetProgramiv( ui_ProgramId, GL_INFO_LOG_LENGTH , &iBufferSize ); => iBufferSize = 0 (no log)
followed by glGetProgramiv( ui_ProgramId, GL_LINK_STATUS, &iLinked ); => everything is fine and the code runs fine.
glLinkProgram => error, without log => LinkStatus ok => code ok
Do you have any idea of the reason of this error 0x0501 please ?
