Use of Cotire tool is introduced for acceleration of CMake builds, by usage of precompiled headers.
CMake option BUILD_USE_PCH is added to enable / disable use of precompiled headers
When precompiled headers are used, additional compiler macros are defined globally in the build system to avoid problems due to different order of included files:
- NOMINMAX is defined on Windows to prevent defining "min" and "max" as macros by windows.h
- STRSAFE_NO_DEPRECATE and _SCL_SECURE_NO_WARNINGS are defined on Windows to prevent declaring functions of standard C library as deprecated by #pragma, and other warnings in system headers
- GL_GLEXT_LEGACY and GLX_GLEXT_LEGACY are defined to ensure that only OCCT's own glext.h is used
- __STDC_FORMAT_MACROS is defined to have standard C print format macros always defined
Code is corrected to avoid conflicts with system headers and in case of compiling together as unity builds (partially):
- Some locally defined variables in TKV3d, TKHLR are renamed to be unique
- Duplicated definitions of macros and global functions are eliminated in TKSTEP
- Useless header WNT_UInt.hxx is removed
- Usage of local variables conflicting with X11 macro is avoided in Draw_Viewer.cxx
- Local variables in AIS_ConcentricRelation.cxx are renamed to avoid conflict with macros defined in windows.h
- HXX files containing code are renamed to PXX or merged with corresponding CXX files.
IVtkTools classes are corrected to avoid compiler warnings disabled in non-PCH builds by inclusion of VTK headers.
Useless pragmas disabling warnings on MSVC are removed
OpenGl_FrameBuffer::InitWithRB() - add method to initialize FBO with Render Buffer Objects.
OpenGl_FrameBuffer::InitWrapper() - add new method to initialize FBO from currently bound in context.
Aspect_RenderingContext - define type explicitly to EAGLContext* / NSOpenGLContext* for ARC.
OpenGl_Window - allow initialization from alien context for OS X / iOS.
OpenGl_Caps::contextCompatible - new option to request compatibility/core OpenGL profile.
OpenGl_Window - request core profile when requested (WGL and Cocoa).
OpenGl_Context::CheckExtension() - retrieve extensions using glGetStringi().
OpenGl_Context::init() - set backward-compatible functions to NULL within core profile:
core11, core15, core20, core32back, core33back, core41back, core42back, core43back, core44back.
OpenGl_Context::BindDefaultVao() - create default VAO required for core profile.
OpenGl_Context::ReadGlVersion() - make method public.
OpenGl_ShaderManager - create programs using GLSL version 150 when available.
OpenGl_VertexBuffer, OpenGl_ShaderProgram, OpenGl_ShaderObject - use
functions set from core profile instead of compatibility.
TKOpenGl - escape deprecated functionality with runtime checks.
Command vcaps - add option -compatibleProfile to request core/compatibility profile.
NIS_View - prevenr rendering within Core profile (unsupported).
Test case for issue CR25854
Aspect_GraphicCallbackStruct::IsCoreProfile - add new field to the struct for NIS
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
