Here’s a clear GitHub issue draft for the ripMIME repo explaining the Termux problem and the minimal fix:

Title: Support custom install prefix in Termux by making LOCATION overrideable

Body:

When building and installing ripMIME on Termux, the default hardcoded install prefix causes failures because /usr/local (the default LOCATION in the Makefile) is a read-only directory in Termux’s environment.

Error observed:

install -d /usr/local/bin
install: cannot create directory ‘/usr’: Read-only file system
make: *** [Makefile:80: install] Error 1

---

Cause:

The Makefile uses a fixed:

LOCATION=/usr/local

which does not respect environment variables or allow specifying an alternate prefix.

---

Suggested fix:

Change the Makefile line to:

LOCATION ?= $(PREFIX)

This allows passing a custom install prefix dynamically via:

PREFIX=/data/data/com.termux/files/usr make install

No other hardcoded /usr/local/bin paths need replacement as the Makefile uses LOCATION for installation paths.

---

Quick patch command:

sed -i 's|^LOCATION=.*|LOCATION ?= $(PREFIX)|' Makefile

This simple change makes ripMIME install correctly in Termux or any other environment with a nonstandard prefix.

---

Thank you for considering this small but important fix to improve ripMIME’s portability!

This is not a bug, you can override variables in the command line.

Instead of:

PREFIX=/data/data/com.termux/files/usr make install

You do:

make install LOCATION=/data/data/com.termux/files/usr
