I see that building csources on termux now works: pkg install libandroid-glob-dev libandroid-glob git clang nodejs pcre pcre-dev libsqlite git clone https://github.com/nim-lang/Nim cd Nim git clone --depth 1 https://github.com/nim-lang/csources cd csources sh build.sh --os android cd ..
However, when I try to run bin/nim compile --os:android koch I get an error that /bin/sh isn't found. I edited lib/pure/osproc.nim as suggested [here](http://stisa.space/articles/compile-nim-on-android/) but I still get the same error.
