Refactor header file extensions from .hxx to .pxx and update include statements.
Enable handling by IDE gxx and pxx extensions as a cpp header files.
Introduce Standard_HIDDEN to hide symbols
The basic implementation of VCPKG as a beta version.
By default will be disabled.
To enable needs to remove CMake cache and reconfigure with BUILD_USE_VCPKG flag to ON.
The current version do not support whole list of 3rd-party, only limited.
and VCPKG_ROOT reachable as a CMake or env variable
Add vcpkg support for FFmpeg and Jemalloc, including configuration files and patches.
QtCreator supports CMake natively.
At the moment OCCT qmake configuration is out-of-date and better to clean.
In case if support of qmake will require for specific platform - can be returned.
But with requirement to be tested by test system Jenkins/GitLab or GH.
Refactor file extension filters in CMake and QMake configurations.
Gxx extension used as a "old-way-template" to repeat .cxx content.
Marking gxx as a source file instead of header.
Moving to absolute path for the gxx integrations.
Refactor precompiled headers and improve Windows compatibility.
Extend TKernel, TKMath and TKBRep pch with more usage headers.
Implement PCH for TKDEIGES, TKDESTEP, TKMesh, and TKXSBase.
Removed cotire PCH
Integrated native PCH by CMake with the same BUILD_USE_PCH flag
Added new option to avoid extra files in 'build/include' folder and replace it by symlink
Symlink creates link to the origin file, it has some benefits from debug and build side.
The CMake parameter for symlink is 'BUILD_INCLUDE_SYMLINK'
The absence of target_link_libraries calls for static libraries caused CMake to fail
in modeling the link dependencies correctly.
This fix ensures that CMake correctly exports the dependencies in OpenCASCADEConfig.cmake and
resolves downstream linking errors for projects that link against static OpenCASCADE libraries.
Integrated DE plugin functionality.
Reworked DE components:
- TKDESTEP: Handling STEP file format.
- TKDEOBJ: Handling OBJ file format.
- TKDEIGES: Handling IGES file format.
- TKDEGLTF: Handling GLTF file format.
- TKDEVRML: Handling VRML file format.
- TKDEPLY: Handling PLY file format.
- TKDESTL: Handling STL file format.
Reworked DE DRAW components:
TKXSDRAWSTEP: Container for DE command to work with STEP.
TKXSDRAWOBJ: Container for DE command to work with OBJ.
TKXSDRAWIGES: Container for DE command to work with IGES.
TKXSDRAWGLTF: Container for DE command to work with GLTF.
TKXSDRAWVRML: Container for DE command to work with VRML.
TKXSDRAWPLY: Container for DE command to work with PLY.
TKXSDRAWSTL: Container for DE command to work with STL.
TKXSDRAW rework to be base DRAW plugin to keep DE session and utils.
Updated documentation
Updated samples
Moved ExpToCasExe and its DLL to new module - DETools
Created new module - DETools to keep tools to DE
Changed definition of main of ExpToCasExe to not const parameter
FlexLexer.h moved to general location into TKernel
Added new CMake variables to build using DRACO
Windows OS works with Debug and Release configuration DRACO
Linux works with Release configuration DRACO
With enabled flag BUILD_USE_PCH we get an error of compilation of TKService:
1>Image_VideoRecorder.obj :
error LNK2019:
unresolved external symbol
"int __cdecl av_strerror(int,char *,unsigned __int64)"
(?av_strerror@@YAHHPEAD_K@Z) referenced in function

(?formatAvError@Image_VideoRecorder@@IEBA?AVTCollection_AsciiString@@H@Z)
1>Media_FormatContext.obj :
error LNK2001:
unresolved external symbol
"int __cdecl av_strerror(int,char *,unsigned __int64)" (?av_strerror@@YAHHPEAD_K@Z)
And many other similar errors. Similar errors occures in some other projects too:
TKService
TKOpenGl
TKOpenGles
TKXCAF
TKXDEDRAW
TKDFBrowser
TKMessageModel
TKMessageView
TKShapeView
TKTInspector
TKTreeModel
TKVInspector
TKView
Proposed solution: turn off cotire from targets, whose compilation cause error while applying cotire tool.
In this ticket migration to cotire 1.8.1 (from 1.7.9) is done.
COTIRE_PREFIX_HEADER_IGNORE_PATH does not apply here, because its employing
causes some errors in 3rdparty libraries (for example, in TKService project).
Projects (TKDFBrowser TKMessageModel TKMessageView TKShapeView TKTInspector TKTreeModel TKVInspector TKView)
which use Qt may be proceeded by cotire tool, but after fixing a bug of cotire:
https://gitlab.kitware.com/cmake/cmake/-/issues/18353
0033153: Fix cotire bug, causing impossibility of compilation targets depending from Qt.
Solution is proposed in:
https://gitlab.kitware.com/cmake/cmake/-/issues/18353
After emploing intel oneTBB of version 2021.5 on NEXT platforms arises error on OCC Pr.:
`
*/ld: */libfreetype.a(truetype.o): relocation R_X86_64_PC32 against symbol `TT_RunIns' can not be used when making a shared object; recompile with -fPIC
*/ld: final link failed: bad value
`
Proposed solution: linking with shared object of libfreetype, rather than with archive library.
Despite that error occurred only in OCC Pr., it is worth to accept changes for OCCT too.
Previous approach do not taking into account, that oneTBB library may be installed in the system folder
on Linux. So, solve the problem it is proposed to employ find_package utility, that works great
as on Windows, as on Linux.
Currently directory containing tbb 3rdparty installation should match the template tbb*.
But after using oneTbb of version 2021.5 standard installation directory is onetbb*.
So, for this 3rdparty modify searching template.
MSVC 2022/c++20.
After employed c++20 language standard errors of compilation in intel oneTBB occurred.
To get rid of compilation errors proposed moving on actual (2021.5.0) intel oneTBB occ products and occt.
After migration errors of compilation of TKernel and TMath have been occurred...
...Error occurred if using c++20 standard with new oneTBB 2021.5.0.
The error was:
Error C2672 'tbb::v1::parallel_for_each': no matching overloaded function found TKernel
could be 'void tbb::detail::d2::parallel_for_each(Iterator,Iterator,const Body &)' TKernel
'tbb::detail::d2::parallel_for_each': the associated constraints are not satisfied TKernel
Note, that if we use c++14 or c++17, all ok, error does not occures.
To solve the problem, i have to modify `UniversalIterator` class:
`value_type` instead `UniversalIterator` converted to `IteratorInterface*`
`pointer` = `reference` = `value_type`
Method `DownCast` moved into `FunctorInterface` abstract class.
argument `UniversalIterator& item` of the unary fuctions converted to `IteratorInterface*`.
The proposed solution removes compilation error.
Affected projects: TKernel, TMath
Affected sources: src/OSD/OSD_Parallel.hxx, src/OSD/OSD_Parallel_Threads.cxx
Affected classes: class OSD_Parallel, OSD_Parallel::UniversalIterator, OSD_Parallel::FunctorInterface, OSD_Parallel::FunctorWrapperIter, OSD_Parallel:;FunctorWrapperInt.
Make C++ standard to be enable from cmake settings:
User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD.
For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available.
To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1.
Available next standard items:
C++11
C++14
C++17
C++20
C++23
This issue consists from several steps to achive main goal:
1) Configuratiuon, CMake - allow selecting C++ standard.
2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD).
3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!)
4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation.
5) Update CMAKE requirements in documentation.
6) Set C++11 standard for several projects.
Integration of ExpToCas tool ported to modern state of OCCT:
- new package Express and toolkit TKExpress for EXPRESS data structures and OCCT class generator
- executable ExpToCasExe including lax/yacc parsers, for parsing a Part 21 file and generating classes
Formatting added files from package Express following OCCT Coding Rules
Changes for correspondence generated files to OCCT Code Rules.
Add generation hxx files with declaration of arrays.
If field is a HArray1 method for get length of array and method for get element of array by its index are generated.
Changes for generation parser from Lex and YACC files.
Update description file ReadMe.md
