Hi, I tried both opam install dune and compiling with make from source on my Redmi Note 11, but compiler could not find:

• some macros like PTHREAD_CANCEL_DISABLE
• related functions like pthread_setcancelstate(int, int*)
  on Android, Termux.

I used to have a unrootable OPPO phone and successfully installed both OCaml 5 and dune inside of its proot-distro alpine linux (Termux emulated Linux environment) but still, that OPPO device was not able to install other packages e.g. utop due to the same pthread related issues. I didn't try to compile utop from source tho.

Now, I switched my device and found it pretty hard to install dune even with proot-distro distributions.

The reason I keep using Android is that my laptop / PC are frequently used for serious tasks which always make me feel stressful so whenever it's possible, I want to stay away from those machines. In fact I gained most of my Linux related knowledge using Termux :3

By modifying configure.ac, OCaml 5 was installed successfully on native Termux; but I could not find any configure.ac inside of this repo, and seems like there's no Android-related code in boot/ either (I found code for win32 & unix in .ml files tho)
