Buildozer opencv error

I got this error when i try building kivy with opencv . Can someone help me?

  STDOUT:

Can you build a project that does not use opencv, such as 'hello world' ( with buildozer defaults)?

[Dinesh]

yeah, without opencv it works fine.

Usually with something like this its because the install instructions need to be repeated

https://buildozer.readthedocs.io/en/latest/installation.html#targeting-android

but sounds like you got that.

Post the full log, maybe there is a clue further up.

Nothing obvious, but the environment is complex and challenging. Nothing wrong with executing buildozer in a Windows file system [from Linux Bash] (except windows won't understand the generated Linux links, so always manage from Linux Bash -and some backup programs will be confused). I have run p4a this way, but the links side effect with Buildozer mean I quickly gave up).

I see the Windows PATH appended to the Bash PATH, and that is normal for WSL But I think are are two C compilers in the Windows part, and that makes me nervous. The message above is from Cmake, was Make picked up from Windows tools somehow? I'm guessing. I know according to the order it should work, but never rely on 'should'; one link can change that order.

Since that setup is intrinsic to WSL (except the two C compilers) and I'm guessing, I won't suggest .bashrc hacking - but if you thought of it, it might be something to try.

Hi,

Are you able to solve it? Please help me. I am facing exactly the same issue.
