Adding `#include ` generates a subsequent error:
```auto

```
I’m guessing this build hasn’t been used or tested in awhile?

Yeah, it would seem so. Isn’t the NDK supposed to be using libc++ these days though?

This is an earlier version of the NDK:

Hi,
i’m the author of [the post](https://discourse.vtk.org/t/vtk-android-compilation-fails-to-find-opengl-librairies/5443) you mentioned, build VTK with recent versions of NDK is still messy but i have retried it because NDK r16b was too old to be used for my own code and others dependencies.
I found another workaround to get VTK compiled with NDK r21e but this time without backend librairies if you don’t need to render things and use only others common functions. Here is the portion of my documentation with instructions:
```
# Install VTK (8.2.0) from sources
cd ~/libs
git clone https://github.com/Kitware/VTK.git
cd VTK
git checkout v8.2.0
# Manually disable those backend modules in CMake/vtkAndroid.cmake
# -DModule_vtkInteractionStyle:BOOL=OFF
# -DModule_vtkRenderingCore:BOOL=OFF
# -DModule_vtkRenderingFreeType:BOOL=OFF
# -DModule_vtkTestingRendering:BOOL=OFF
# -DModule_vtkRenderingVolumeOpenGL2:BOOL=OFF
mkdir build && cd build
cmake .. \
-DVTK_ANDROID_BUILD=ON \
-DANDROID_NDK=$ANDROID_NDK_PATH \
-DANDROID_NATIVE_API_LEVEL=28 \
-DANDROID_ARCH_ABI=arm64-v8a \
-DCMAKE_BUILD_TYPE=Release
make -j8
cp -r CMakeExternals/Install/vtk-android/* $ANDROID_ARM64_V8A_INSTALL_PREFIX
```
But i don’t giving up to make thoses backend librairies found by linker with recent NDK versions.
I hope this can help you.

For info, I am currently working on it. See [https://gitlab.kitware.com/vtk/vtk/-/merge\_requests/8163](https://gitlab.kitware.com/vtk/vtk/-/merge_requests/8163)
Still facing issues with some math functions (isnan, isfinite, etc).

Just updating here that the recent changes in [!8163](https://gitlab.kitware.com/vtk/vtk/-/merge_requests/8163) once again allow VTK to be build for Android.

Hi:
I am trying to build vtk on android by ves
I use:
ubuntu 22.4
gcc 10.4
vtk9.2.2 (I change the url on vtksuperbuild.cmake)
after run
make -j4
I meet the problem as shown in attachment "terminal”
In attachment “CMakeOutput”, it seems that OFF\_T\_64 is not big enough, cause it return value 1.
It seems that the error occur in attachment “build.make” line 92,
Here is other two related screen shots.
Thanks very much

Hello,
We no longer support VES. You can build VTK directly for Android now using something like the following:
```auto
$ ccmake -DVTK_ANDROID_BUILD=ON \
-DANDROID_NDK=/path/to/android-ndk-r21e/ \
-DANDROID_NATIVE_API_LEVEL=27 \
-DANDROID_ARCH_ABI=arm64-v8a \
../vtk
```
Please see the previous comments and PRs mentioned above.
Thanks,
TT

Hi, I built vtk-android from source but I can not find any apk files that I can intall onto my phone…
In the end of this official readme file indicates that there should be some apks after build.
[https://gitlab.kitware.com/vtk/vtk/-/tree/master/Examples/Android](https://gitlab.kitware.com/vtk/vtk/-/tree/master/Examples/Android)
I appreciate any help 🙂
