Expected Results

5. Build command failed.
   Error while executing process D:\ADK\cmake\3.10.2.4988404\bin\ninja.exe with arguments {-C D:\XXXXXXXXXXX\Main\Project\Project\XXXXXXX\src\mobile\node_modules\react-native-pytorch-core\android.cxx\cmake\debug\armeabi-v7a torchlive}

6. If you run the cmake on clion, you will see this warning. I am not sure it is the reason.

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

In addition, I also tried to use the newest Live Core. Currently, It still has issues with the CMake:
https://github.com/pytorch/live/blob/main/react-native-pytorch-core/android/CMakeLists.txt

[JonathanSum]

It is possible that this wrong setting caused this:

[Gernii]

@JonathanSum u need to up or downgrade your react native to v0.65.1, I have tested all version, and only v0.65.1 work

[JonathanSum]

@Gernii
I will try your suggestion next week. After that, I will close it, if you are right.

[clarksandholtz]

@JonathanSum any luck with @Gernii's suggestion?

[JonathanSum]

@clarksandholtz

It was my final year and final semester of my school, so it was so busy. I am currently starting to try @Gernii's solution.

The RN I am currently using is "react-native": "0.64.3", and I am going to update it.

I hope it can work from 0.65.1 or above.

I will try to fix it this weekend. I am pretty busy right now.

[JonathanSum]

So it can only work in 0.65.1 at this momoment?

[Gernii]

@JonathanSum v0.1.3 only work with v0.65, i dont know how lib demo work with v0.64, if u want to work in v0.66+, u have to wait for lib next version, if u still want to use in v0.66+ u can use '@nightly'.
Example: react-native-pytorch-core@nightly
This will take latest commit, not latest version, you can see in #50
Warning: this can cause bug because maybe latest commit have bug

[raedle]

@Gernii and @JonathanSum, the latest nightly has support for up to React Native 0.68. React Native 0.69 is not yet supported, but we are also looking into supporting it.

The fix for 0.68 has been added in commit fix RN0.68 can't build with react-native-pytorch-core, which is currently only available in the nightly version.

Please have a look at the docs "Add Package to Existing App" for more information how to set up the project.

Can you let us know if this unblocks you?

[JonathanSum]

Closing this because my issue was solved in another way.

[JonathanSum]

@raedle I will try to add it to my project with my OnePlus7 later to see if this unblocks me or not.
