Free Pascal Operating System, version NEXT

The NEXT version of the Free Pascal Operating System.

Starting from scratch with Bootboot's example, FPOS now lives again!

Requirements

• Free Pascal Compiler 3.2+, able to compile for x86_64 Linux
• ld, strip, readelf - for supported AND target platform (see below) x86_64
• Bootboot's mkbootimg
• Make
• grub2-mkrescue and xorriso (optional)
• QEMU/VirtualBox/VMWare (to try out the image)

If you want to test the image, better use QEMU. VirtualBox + VMWare on Windows are confirmed to not working (yet).

Real hardware is not tested yet.

Build steps

Clone this repository.

There are multiple options to create a FPOS that you want.

Go read the Environment variables section below.

To compile and create a bootable disk image:

$ make all

To compile:

$ make fpc_all

To create disk/cdrom image:

$ make disk

To create an ISO (requires grub2-mkrescue and xorriso):

$ make grub.iso

To boot in QEMU:

$ make boot

To boot in QEMU using generated GRUB iso:

$ make boot-grub

To regenerate Makefile (requires fpcmake):

$ make makefiles

Or:

$ fpcmake -w -Tall
