| 47 | pmbaty | 5 | __ifstool__ is a portable open-source reimplementation of [QNX 8.0's mkifs](https://www.qnx.com/developers/docs/8.0/com.qnx.doc.neutrino.utilities/topic/m/mkifs.html), 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. |

| 7 | As an illustration, the bootable QNX8 IFS pictured in the above screenshot was built using __ifstool__. |

| 47 | pmbaty | 9 | 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](listing.php?repname=QNX%208.QNX8%20GNU%20binutils)) can be used as a drop-in replacement. |

| 11 | ## Language |
||
| 12 | |||
| 13 | POSIX-compliant ANSI C99. |
||
| 14 | |||
| 15 | ## IDE |
||
| 16 | |||
| 17 | The development environment used was [Microsoft Visual Studio](https://visualstudio.microsoft.com). A Visual Studio 2022 solution file is supplied. |
||
| 18 | |||
| 19 | ## Dependencies |
||
| 20 | |||
| 47 | pmbaty | 21 | * Oberhumer's [miniLZO](https://www.oberhumer.com/opensource/lzo/#minilzo) compression library (supplied) |
| 22 | * Oberhumer's [UCL](https://www.oberhumer.com/opensource/ucl/) compression library (supplied) |

| 24 | ## How to build |
||
| 25 | |||
| 26 | * For __Win32__: open Visual Studio project -> Build. |
||
| 47 | pmbaty | 27 | * For __QNX8/x86-64__: run `make.cmd` (if using Win32) or `make.sh` (if using a POSIX platform). |
| 28 | * 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. |
||
| 29 | * For __GNU/Linux__: run `make.sh` |
||
| 30 | * For __FreeBSD__: run `make.sh` |
||
| 31 | * For __macOS/Darwin__: run `make.sh` -- yes, it works on macOS too :) |
