IFS Tool for QNX

ifstool is a portable open-source reimplementation of QNX 8.0's mkifs, that is able to pack, unpack and analyze x86_64 BIOS and UEFI QNX IFS images, compressed or not, bootable or not, using the same script file-based syntax as mkifs. Most of the mkifs options are supported. Can be built as a native QNX tool. Already used in production in some places.

As an illustration, the bootable QNX8 IFS pictured in the above screenshot was built using ifstool.

The goal was to turn QNX8 into a self-hosted platform. Since QNX no longer supplies a native toolchain (compiler, linker, binary utilities, IFS utilities) ifstool, when used along with the GNU linker (cf. QNX8 GNU binutils) can be used as a drop-in replacement.

Language

POSIX-compliant ANSI C99.

IDE

The development environment used was Microsoft Visual Studio. A Visual Studio 2022 solution file is supplied.

Dependencies

• Oberhumer's miniLZO compression library (supplied)

• Oberhumer's UCL compression library (supplied)

How to build

• For Win32: open Visual Studio project -> Build.

• For QNX8/x86-64: run make.cmd (if using Win32) or make.sh (if using a POSIX platform).

• For QNX8/aarch64le: run make.cmd (if using Win32) or make.sh (if using a POSIX platform). Note the bootable IFS feature on this target is untested.

• For GNU/Linux: run make.sh

• For FreeBSD: run make.sh

• For macOS/Darwin: run make.sh -- yes, it works on macOS too :)

Feedback is welcome.
