The above is the debug information output of different versions, in which the compilers found by CC_armv7-linux-androideabi are different.

bbqsrc commented 1 year ago

I understand your assertion in the title is that it does not correctly find the compiler. Yes, there has been a change in how the linker is called between those two versions to work around a bug with the NDK.

If you have a build issue, please provide the issue that you're facing there, as a change in a value in the environment variables is not inherently a bug.
