Problem compiling using Android NDK

This is the error I face when setting up crossenv. Kindly rectify this.

why r25b ? isn't current LTS r26b ?

[anshm-2166]

Tried with ndk r26b too, doesn't make any difference

While I get this set up, can you run with -vv to get debug output? That might give us a clue about what's going wrong.

Also: Which Python version(s) are you using?

[anshm-2166]

Python 3.11.7

I also face to similar problem. Version of Python is 3.15.0a0, both the build as well as the host (cross-compiled). Cross-compilation did well, the resulting binaries seem to be working in Android devices. The Debian used does not contain any other Python installation. As soon as I try to create the virtual environment, such typical error alert occurs (independent on the Android platform chosen, either arm-linux-androideabi like here, or aarch64-linux-android, i686-linux-android, x86_64-linux-android):

Use --cc to correct, if necessary.
