Update target_link_libraries to use PUBLIC and PRIVATE visibility for dependencies.
Now all 3rd-party is hidden for the external linking, no more issues to invalid path to 3rd-party
Reorganizing structure to have Module/TK/Package/FILES structure.
New structure reflect the structure inside IDE.
Migrate FILES, PACKAGES, EXTRLIB to CMake version to handle changes on updates.
No changes were done to installation layout, all installation result keep as before.
The migration was done using python script, see PR, which refactor automatically the structure.
Updated doc generation to have valid path to modules, toolkits and packages.
In case of PR into new version, IR-790 can be used as a target for the previous version.
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.
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'
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.
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.
SEARCH_TEMPLATES was modified to find EGL and GLES2 libraries in different folders (angle-gles, egl-gles, egl, angle, etc).
Find 3rdparty products procedure allows to define 3RDPARTY_LIBRARY_DIR or 3RDPARTY_DLL_DIR manually to find necessary libraries and dlls.
Extending CMake procedure by 'BUILD_MODULE_QtSamples' variable to switch on qt samples build.
Implementation required:
- union of occt_toolkit_tool.cmake and occt_toolkit.cmake files;
- correction of qt samples sources by adding path to Qt 'plugins' folder. It helps to avoid definition of additional variable (QT_QPA_PLATFORM_PLUGIN_PATH) when staring sample.bat for qt samples;
- executable processing is extended in cmake procedure by providing 'EXECUTABLE_PROJECT' variable. Now we need not specify custom processing for DRAWEXE in occt_toolkit.cmake
OCCT_INSTALL_BIN_LETTER is used only on Windows (isn't depended on type of generator) because bind/libd/bini/libi folders are not used on Linux (only bin and lib)
'BUILD_Inspector' CMake option switches ON/OFF Inspector in compilation procedure (add additional dependency to Qt third party product)
'inspector.bat' starts sample to demonstrate possibilities of this tool.
Replacing TOOLS to INSPECTOR key for 'pload' command in DRAW cases due to this change in DrawPlugin.
The following implementation has been made:
- CMake procedure is extended to compile Qt tools. This is optional and is handled by USE_QT_TOOLS option(OFF by default)
- It is possible to build Qt tools using Qt5 or Qt4, it is settled with USE_QT4 option.
- Sample of DFBrowser tool is available in samples/tools/TInspectorEXE. It is build with tools, executable is placed in binaries. To start the sample, use dfbrowser.bat command.
- DFBrowser tool may be started from DRAW
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
Generation of header files from resource files was added to CMake and genproj procedures.
Message_MsgFile has been extended with new method ::LoadFromString()
for loading messages from embedded resources.
Message_MsgFile::LoadFromString() is now a preferred way
for loading message resources by application
as alternative to environment variables.
TObje/TObj.msg is now embedded into TObj_Application.cxx.
TObj_Application now loads its global messages
on instantiation of the first class instance.
UnitsAPI/Lexi_Expr.dat now completely embedded into Units_Lexicon.cxx.
UnitsAPI/Units.dat now embedded into Units_UnitsDictionary.cxx
but can be regenerated from resource file.
The definition of the following units have been removed:
benne à charbon, calorie (diététique).
Unused message files XSMessage/IGES.us and IGES.fr have been removed.
Related code IGESData.cxx has been removed as well.
XSMessage/XSTEP.us is now embedded into Interface_StaticStandards.cxx
and used for fallback initialization in case when file resources
defined by CSF_XSMessage environment variable are missing.
SHMessage/SHAPE.us is now embedded into ShapeExtend.cxx
and used for fallback initialization in case when file resources
defined by CSF_XHMessage environment variable are missing.
Duplicating code has been removed from ShapeProcess_OperLibrary.cxx.
Shaders/Declarations.glsl and Shaders/DeclarationsImpl.glsl
are now embedded into OpenGl_ShaderProgram.cxx.
CSF_ShadersDirectory is no more required for using OCCT 3D Viewer.
Ray-Tracing GLSL programs from Shaders are now embedded into OpenGl_View_Raytrace.cxx.
File resources are still used instead of embedded programs
when CSF_ShadersDirectory is defined, but this functionality
is intended for OCCT development.
Enumeration Graphic3d_ShaderProgram::ShaderName_Phong
demonstrating custom GLSL program usage has been removed.
Enabled creation of CMake target files (one per module) for OCCT at install time.
Variables enumerating available OCCT toolkits by module are added in CMake configuration file.
Added check of availability of OCCT modules specified by OpenCASCADE_FIND_COMPONENTS variable.
Location of CMake configuration and target files in Windows layout is changed to $INSTALL_DIR/cmake (thus common for all configurations), to be found by standard search logic of CMake find_package() function.
