Install babylonjs native

I have been trying to build for my windows using cmake -A x64…but I get the following error

C:/Users/adene/Downloads/BabylonNative/Build" does not appear to contain CMakeLists.txt.

Drigax · September 30, 2020, 2:10am

Try cmake -A x64 ..\
Since we ask for a build subfolder, we need to tell cmake that the parent folder is where our project files are.

waverider404 · September 30, 2020, 2:18am

     NMake Makefiles

does not support platform specification, but platform

x64

was specified.

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

now i got this

I can’t reproduce these issues, but let’s make sure we have all the build dependencies installed. I’m assuming this is windows 10:

Is cmake for windows installed?
Is git for windows installed?
Have all git submodules been initialized?

Is visual studio 2019 installed with C++ development tools?
And is Python 3 installed and available from the command line?

finally got it working

Drigax · September 30, 2020, 3:24am

Nice! Have fun!

@Drigax
also, I have these errors in android studio…ninja is installed, I made sure I was using pixel 2 API 27

Adding @Cedric and @bghgary

@waverider404 I’m 90% sure it’s because of path length with Windows/Android Studio. Can you try to clone the repo in a short length named directory (like c:\BN instead of C:/Users/adene/Downloads/BabylonNative-master/BabylonNative-master/BabylonNative).
I had the same issue some time ago and enabling long path support in Windows didn’t help. I guess some path length is limited to MAX_PATH somewhere…

@Cedric

I finally got it to install on the emulator but now the app crashes with the following error

10:41 AM	Emulator: C:\buildbot\src\android\emu-master-dev\external\qemu\android\android-emugl\host\libs\Translator\GLES_V2\GLESv2Imp.cpp:glTexImage2D:3389 error 0x501

Can you check your emulator opengl es 3 settings ?

### Using the Android Emulator

- Install HAXM by again opening the SDK Manager, checking *Intel x86 Emulator Accelerator (HAXM installer)*, then clicking *Apply*. If the installer fails, see [HAXM Installation Troubleshooting](#HAXM-Installation-Troubleshooting).
- Create an Android Emulator through the AVD Manager (Android phone icon in the upper right). Pixel 2 with API 27 has been tested.
- In Android Studio, click the *Run->Run App* menu item and select your device if prompted.

### HAXM Installation Troubleshooting

The HAXM installer can fail for a number of reasons. Many solutions are discussed in [HAXM issue 105](https://github.com/intel/haxm/issues/105), including:

- Enabling Intel virtualization in the bios
- Disabling Hyper-V in Windows
- Disabling memory integrity in Windows
- Disabling virtualization security with the Device Guard and Credential Guard hardware readiness tool

### OpenGL ES 3 and AR settings

Open GL ES3 is required on Android Emulator. Otherwise one will run into the following errors when deploying it onto the Android Emulator:

I guess the problem lies with my emulator not supporting gles3, so i tested it directly on my tablet and it works

waverider404 · October 12, 2020, 12:36am

it seems babylonjs gui does not work in the native engine and also how can I disable anti-aliasing for optimisation purpose?

Cedric · October 12, 2020, 8:19am

GUI doesn’t work yet but it will in the coming weeks. There is no easy way to disable AA. The flag in only set on the c++ side with no way to change it without a rebuild.
