Summary0024546: GCC compiler warnings in OpenGl
DescriptionAs far as I can see from last Jenkins logs (, there are several new compiler warnings on Linux in the current master.

The first is likely brought by fix of 0024320:

OpenGl_Texture.hxx:152: ‘OpenGl_TextureFormat::myChannels’ will be initialized after
OpenGl_Texture.hxx:149: ‘GLint OpenGl_TextureFormat::myInternal’
OpenGl_Texture.hxx:139: when initialized here

The others are reported in a code which has not been touched for a while, and I wonder why most of them are not reported in previous build logs:

OpenGl_SceneGeometry.cxx:381: dereferencing type-punned pointer will break strict-aliasing rules

OpenGl_Workspace_2.cxx: ‘GLsizei getNearestPowOfTwo(GLsizei)’ defined but not used

OpenGl_Workspace_2.cxx:60: ‘void fitDimensionsRatio(Standard_Integer&, Standard_Integer&, Standard_Real)’ defined but not used

OpenGl_Workspace_Raytrace.cxx:104: ‘_cl_mem* clCreateImage2D(_cl_context*, cl_mem_flags, const cl_image_format*, size_t, size_t, size_t, void*, cl_int*)’ is deprecated (declared at /dn29/PRODUCTS/maintenance/unix_6.6.1/opencl-icd-

This warning will likely disappear if OpenCL code is eliminated in context of 0024739

It looks all the warnings above have been eliminated, though new ones appeared, reported in 0024875

I see no these warnings in recent build logs, consider it as fixed
