Added support of Visual Studio 2017 (15) in CMake build procedure.
CMake 3.7.2 or above is required to generate projects for VS 2017.
Since version of compiler and toolset remained at 14 (now they are 14.1), and they use the same run-time, the same third-party products as for VS 2015 (14) can be used.
Also the name of the folder for installation of OCCT binaries in OCCT-standard layout (default on Windows) remains "vc14".
Support of Visual Studio 2017 is added in genproj generator and relevant environment, with format specifier "vc141".
The syntax of the genproj command is revised:
- UWP is considered as separate platform ("uwp" alternative to "wnt"), not part of IDE specification
- Option "IDE" is renamed to "Format"
- Obsolete name of local variable "aWokStation" is replaced by equivalent "theFormat"
In environment scripts, additional variables are defined (derived from VCVER, see adm/vcver.bat):
- VCLIB defines name of the subdirectory specific to VS version; it is the same as VCVER except that for VCVER=vc141 VCLIB=vc14 and for VCVER=141-uwp VCLIB=vc14-uwp
- VCFMT is VCVER without optional suffix "-uwp"
- VCPROP is "NativeDesktop" for normal builds or "Universal" for UWP builds
Command genconf is amended to:
- Detect presence of VS 2017 (separately for desktop and UWP)
- Use only two first digits after "vc" in format specification for search of third-party libs
- Have more space in user interface for VS specification
All supported variants of VCVER variable are documented in dev guides / buiding / msvc
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
Patch removes option -wd4996 from VS project settings (which suppresses old deprecation warnings).
Instead, macros _CRT_SECURE_NO_WARNINGS (suppresses 444 warnings) and _CRT_NONSTDC_NO_DEPRECATE (suppresses 17 warnings) have been added.
Deprecation warning on GetVersionEx() has been suppressed locally in OSD_Host.cxx.
In STEPConstruct_AP203Context.cxx, OSD_Host is used instead of low-level system functions.
This eliminates dependency of TKSTEP on winsock32.lib on Windows.
Adaptations for compiling with GCC 4.7 and 4.8:
- Construction semantics is used for Handle objects being initialized by const Handle objects of derived type, to avoid overload resolution error in GCC 4.7.
- Missing includes added.
- Fixed bugs related to misuse of direct casts of handle.
- Eliminate CLang warnings on uninitialized and unused variables, functions, and expressions
Simple primitives to parallelize loops type "for" and "foreach" were implemented. The primitives encapsulates complete logic for creating and managing parallel context of loops. Moreover the primitives may be a wrapper for some primitives from 3rd-party library - TBB.
To use it is necessary to implement TBB like interface which is based on functors. For example:
Class Functor
{
public:
void operator() ([proccesing instance]) const
{
//...
}
};
In the body of the operator () should be implemented thread-safe logic of computations that can be performed in parallel context. If parallelized loop iterates on the collections with direct access by index (such as Vector, Array), it is more efficient to use the primitive ParallelFor (because it has no critical section).
All parts of OCC code which are using tbb were changed on new primitives.
0024826: Wrapping of parallelisation algorithms
Small fix.
Function perf_sprint_all_meters added in OSD_PerfMeter.h to allow printing to string buffer rather than stdout. Macro PERF_PRINT_ALL converted to functional form.
Command dperf added in DRAW to print and conditionally reset all meters.
Description of these tools is added in Debug Hints.
Modified output of command QANTestNCollectionPerformance.
Added test case perf/ncollection/A1
Modified ratio of performance to check all platforms
Small correction of test-case for Windows platform
STL-compatible iterators returned methods begin() and end() are provided in collection classes from NCollection package.
NCollection_Array1::Iterator is redesigned to use pointer instead of index.
Iterators of Sequence, Array, and Vector are extended by new methods to iterate backwards.
Use of SortTools_QuickSortOfReal is replaced by std::sort() in a few places (where possible).
