Emacs for Android with Termux fails to execute most subprocesses: readlink('/proc/self/exe') failed

Emacs for Android with Termux fails to execute most subprocesses: readlink('/proc/self/exe') failed

[Romário Rios via Users list for the GNU Emacs text editor]

Hello,

I've just downloaded the Android+Termux port of Emacs from here: https://sourceforge.net/projects/android-ports-for-gnu-emacs/files/termux/

I followed the instructions (install Termux first, then install Emacs), then I opened Emacs and tried to edit .emacs

Emacs froze immediately.

Then I forced emacs to close and tried again, this time doing M-x shell RET

Emacs froze again.

I then (after closing and reopening Emacs) opened eshell and tried to execute *anything* besides basic stuff like ls and this is what I get:

$ sh
readlink('/proc/self/exe') failed: Bad file descriptor

And then the shell hangs.

Any idea why this happens? This doesn't happen with the normal Emacs from Fdroid.

I'm running the armeabi-v7a version of Emacs. My phone is not rooted and I'm running Android 10.

Thanks in advance.

I think this issue arises from within the armeabi-v7a process tracing
code, which I wrote blindfolded at the time absent any devices to test
on.  I will investigate this.

This should now function correctly; prebuilts will be generated
forthwith, as usual.

Thank you for the very quick response! Should I reinstall both Termux and Emacs or just Emacs?

Thanks!

Just downloaded and installed the latest version and the problem still happens, unfortunately:

$ sh
readlink('/proc/self/exe') failed: Bad file descriptor

Would you please submit a bug report to bug-gnu-emacs@gnu.org?  The
information generated by `M-x report-emacs-bug' might prove helpful.

TIA.

`M-x report-emacs-bug' hangs too. What do I do now?

That's very strange.  Do you have access to a non-Android computer from
which this problem can be investigated further?
