Summary0028135: Configuration - adopt building script for using built-in Android cross-compiling support in CMake 3.7
DescriptionCMake 3.7 introduces built-in support for Android platform (in contrast to third-party toolchain for CMake). This procedure should be analyzed and OCCT CMake scripts / Readme should be updated if needed.

https://cmake.org/cmake/help/v3.7/manual/cmake-toolchains.7.html#cross-compiling-for-android [^]
Steps To Reproduce• Set variable CMAKE_ANDROID_NDK equal to yout Android NDK path in file occt\adm\templates\android.toolchain.config.cmake
• Run CMake 3.7.x as usual
• Press Configure -> Select "MinGW Makefiles" generator and use third checkbox (about toolchain file) -> Next
• Select file occt\adm\templates\android.toolchain.config.cmake
• Repeat all other steps as usual (set install/3rd-party directories, etc)
• Build and install solution
TagsNo tags attached.

 CMake warning CMP0054 appears because line 222 from file "occt/adm/cmake/occt_toolkit.cmake":

if (NOT "${CURRENT_CSF}" STREQUAL "")

in case of Android build, variable CSF_ThreadLibs contains "c" string.
Also, variable "c" is defined in CMake.
Because of these two factors warning CMP0054 appears.

 I have checked compilation of occt for Android platform using this patch on CMake 3.7.0 and 3.7.1.

Documentation was updated.

+Note that CMake supports Cross Compiling for Android with simple toolchain files since version **3.7.0**.

The references to obsolete solution should be eliminated from documentation.

 Remark from abv,

in OCCT 7.1.0 release notes:
On configuration step of CMake, select "Visual Studio 14 2015" as generator
and specify optional toolset, pointing to the file
adm/templates/uwp.toolchain.config.cmake located within OCCT sources.
Alternatively, run CMake with options -DCMAKE_SYSTEM_NAME=WindowsStore -DCMAKE_SYSTEM_VERSION=10.0.


Please extend the OCCT documentation with similar suggestion for UWP and Android which does not require using addition toolsets just defining 2-4 additional CMake variables.

 I see on the screenshot, that CMake chooses gcc as compiler in NDK (NDK provides two options - gcc and CLang, we prefer gcc for now).

But is there some information concerning which C++ standard library / STL implementation is used (gnustl_static / gnustl_shared / stlport_static / stlport_shared)?
(0061992)
ski (developer)
2016-12-22 11:21

 It is possible to add one more variable to android toolchain file (or use it from command line):

CMAKE_ANDROID_STL_TYPE
    Set to specify which C++ standard library to use. If not specified, a default will be selected as described in the variable documentation.
(see https://cmake.org/cmake/help/v3.7/variable/CMAKE_ANDROID_STL_TYPE.html#variable:CMAKE_ANDROID_STL_TYPE [^])

kgv (developer)
2016-12-22 11:41

 > The default value is gnustl_static.
Please set this variable to "gnustl_shared" and provide description in our documentation.
