Build tools are updated to support building with Visual Studion 2019 toolset ClangCL (LLVM clang-cl):
- In CMake builds, use of unsupported option "-std=c++0x" is avoided
- Tool genconf recognizes availability of ClangCL toolset and proposes it in the list
- Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it
Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT.
Code is updated to build with Clang for Windows without errors and warnings:
- In BVH classes, pure virtual destructors are replaced by empty ones, to avoid bogus compiler warning
- In .lex files, pragmas are added to disable warnings in parser code
- In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior)
- In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled
- In Quantity_ColorRGBA and ViewerTest_CmdParser, incorrect use of predefined macro __FUNCTION__ assuming it was a string literal is avoided
- In Standard_Macro.hxx, code is reordered to handle Clang for Windows appropriately
- In AdvApp2Var_SysBase.hxx, inclusion of obsolete (MSVC-specific) header file is replaced by Standard_TypeDef.hxx
- In Standard_ErrorHandler.hxx, empty statements added to avoid warning on unused class fields
- In IVtkDraw and ViewerTest, interface is corrected to use actual type avoiding unnecessary type casts
Off-topic: corrections of some errors (uninitialized class fields) reported by VS Code Analysis in TKernel
Added adm/qmake/Occt.pro for building OCCT using Qt Creator.
genproj/genconf scripts have been extended with an option defining project format.
Draw_Appli now tries resolving CASROOT/DRAWDEFAULT/CSF_OCCTResourcePath/CSF_OCCTSamplesPath
locations within usual OCCT development/installation environment.
Added missing TKShHealing dependency to TKDraw/DRAWEXE (inherited from TKMesh).
OSD_Process::ExecutableFolder() - added method returning executable folder.
Names of Windows header files are corrected to be lower case to match their actual names on Windows (except Windows.h) and MinGW.
Files COMMANDWINDOW.h and MAINWINDOW.h in Draw package are renamed to CamelCase according to names of corresponding CXX files.
All library-specific macros for defining export / import properties of symbols on Windows (like Standard_API, __Draw_API, _math_API etc.) are eliminated.
Common macro Standard_EXPORT is used in all places where it is necessary.
New macro OCCT_STATIC_BUILD is defined for disabling Standard_EXPORT, to be used instead of HAVE_NO_DLL, though the latter is still supported as well (for compatibility).
To allow building OCCT in static mode on Windows after these changes:
- Files OSD_WNT_1.hxx and OSD_WNT_BREAK.hxx are removed; useful declarations are moved to OSD_WNT.hxx
- In the class IVtkVTK_ShapeData, static fields ARRNAME_MESH_TYPES and ARRNAME_SUBSHAPE_IDS are converted to static inline functions
- Global array ChoixRef defined in IntImp_ComputeTangence.cxx is converted to static function returning element of the array by index
- Unused class Quantity_Convert is removed (it had static field accessed by inline method)
- Struct Approx_Data defined in the same way in BRepApprox_Approx.hxx and GeomInt_WLApprox.hxx is made private member of these classes to avoid name clash
- Some C++ files producing no object code are removed
- In NCollection_EBTree.hxx and StdLPersistent_Collectio.hxx, definition of template virtual method is moved to class definition to avoid MSVC linker warnings on unused symbols
Method OSD_Process::Spawn() is removed as useless (not used across OCCT or products).
Note that on Linux, macOS, and Windows standard C function "system()" can be used directly instead, while iOS apparently does not support spawning separate processes at all.
The macros Status, Convex, Opposite, FillSolid (coming from X11 headers)
are now undefined in place of definition of methods with same name in OCCT headers.
The usage of variables with name Status is now avoided.
GL_GLEXT_LEGACY is now defined only if not already defined.
The macros AddPrinter (coming from WinAPI headers) is now undefined
within Message_Messenger class definition having method with the same name.
CurrentDirectory macro is now undefined in OSD_Process.hxx.
Eliminated usage of ANSI methods.
All Visual Studio projects generated by genproj or CMake use Unicode character set.
Draw Harness now handles Unicode input on Windows.
Tcl test scripts are now expected in UTF-8 encoding by default.
TCollection_ExtendedString/TCollection_AsciiString description
has been updated to reflect usage of this classes for Unicode strings.
TCollection_ExtendedString now defines constructor taking wchar_t* (all platforms)
and method ::ToWideString() returning wchar_t* (Windows only).
TCollection_AsciiString now defines constructor taking wchar_t*.
TCollection_ExtendedString/TCollection_AsciiString now defines
auxiliary methods ::StartsWith() and ::EndsWith().
TCollection_ExtendedString internals has been updated to eliminate
duplicated code for converting between UTF-16 and UTF-8.
Code has been cleaned up from redundant explicit conversions to wchar_t*.
Global method OSD_OpenStream()/OSD_OpenFileBuf() have been replaced
by C++ template to eliminate copy-paste for different STL collections.
OSD_SharedLibrary now uses wide-char system API call LoadLibraryExW()
on Windows for consistency.
New macro Standard_UNUSED has been added for marking possibly unused functions and variables
(to suppress gcc/clang compiler warnings).
- Toolchain file to configure a Visual Studio generator for a Windows 10 Universal Application was added (CMake).
- There is no support for environment variables in UWP.

- Building of unsupported modules for UWP platform is off by default .
- Checking of DataExchange functionality was added to XAML (UWP) sample.

- Update of results of merge with issue 27801
AIS_ColorScale, AIS_Dimension - the protected method DrawText()
has been renamed to drawText() to avoid name collisions with macros.
_MSC_VER/_WIN32 misuse has been fixed in several places.
Header <malloc.h> is now included where alloca() is used.
Draw_Window - dllimport flag has been dropped from inline methods.
TKernel - mandatory dependencies Winspool.lib and Psapi.lib
are now linked explicitly (instead of msvc-specific pragma syntax).
CMake scripts - the option -std=c++0x has been replaced by -std=gnu++0x
for mingw to allow extensions (like _wfopen() and others).
The minimum Windows version has been set to _WIN32_WINNT=0x0501.
Invalid options "-z defs" and "-lm" have been dropped for mingw.
Flag --export-all-symbols has been added to CMAKE_SHARED_LINKER_FLAGS
to workaround missing vtable symbols when using mingw.
FreeType is now linked explicitly on Windows.
Draw::Load() - "lib" suffix is now prepended on mingw as well.
Drop redundant declaration of _TINT from OSD_WNT_1.hxx.
NCollection_UtfString::FromLocale() - platform-specific code has been moved to .cxx file.
Draw_BasicCommands - fixed incorrect mingw64 version macros.
genproj, cbp - added workaround for process argument list limits on Windows.
TKSTEP linkage is failing on this platform due to too long list of files.
The list of object files to link is now stored in dedicated file which is passed to gcc.
Option "-z defs" removed from CMake linker options to avoid problems when building with different configurations of VTK on Linux
Some MinGW-specific compiler warnings (potentially uninitialized vars, use of NULL, parentheses in conditional expressions) are fixed (speculatively)
Check return code of fgets() and system() within FSD_BinaryFile::ReadChar(),
IFSelect_SessionFile::ReadFile(), IFSelect_SessionPilot::ReadScript(),
OSD_File::Print(), OSD_Process::Spawn(), RWStl::ReadAscii(), iges_lire().
- Class OSD_EnvironmentIterator is removed (not used, and would definitely fail under Windows if tried)
- Methods UserId() and GroupId() removed from OSD_FileNode (cannot be made portable, as there is no integer IDs of user and group on Windows)
- Draw_ProgressIndicator corrected to properly pass address via Tcl
- OSD_File.cxx: local function is refactored to avoid senseless encoding / decoding of results
- OSD_Process::UserId() method removed, as it cannot be made cross-platform (no integer IDs on Windows)
- OSD_Thread: use WinAPI conversion functions to avoid warnings
- OSD_WNT.cxx: recursion counter passed via function argument instead of TLS
- TDF_LabelMapHasher revised to use correct hasher function for an address
