A execve()
wrapper to fix problem with shebangs when running in Termux.
A lot of Linux software is written with the assumption that /bin/sh
, /usr/bin/env
and similar file exists. This is not the case on Android where neither /bin/
nor /usr/
exists.
When building packages for Termux those hard-coded assumptions are patched away - but this does not help with installing scripts and programs from other sources than Termux packages.
Create an execve()
wrapper that rewrites calls to execute files under /bin/
and /usr/bin
into the matching Termux executables under $PREFIX/bin/
and inject that into processes
using LD_PRELOAD
.
pkg install termux-exec
./bin/sh
and /usr/bin/env python
should work.The $PREFIX/bin/login
program which is used to create new Termux sessions checks for
$PREFIX/lib/libtermux-exec.so
and if so sets up LD_PRELOAD
before launching the login shell.
