Failed to compile on Termux Android

[T0MuX]

Hi,

I'm using Termux on Android. I would like to install wcp on it, but the compilation fails at the make step. I just followed the readme instructions. Also, I just noticed the readme says "It should work on any kernel >= 5.6" while my Android is using 5.4 version. Maybe it's just that ?

$ uname -a
Linux localhost 5.4.242-qgki-g3f7ff67280a0 #1 SMP PREEMPT Sun Mar 17 23:13:51 HKT 2024 aarch64 Android

The cmake step worked like a charm btw. And then, the make step with errors :

I don't completly understand, but maybe this topic can help ? https://stackoverflow.com/questions/53075327/use-of-undeclared-identifier-pthread-recursive-mutex-initializer-np

Sorry, neither your kernel version, nor android in specific are supported.
