I was trying to do the first build from haiku source code:
1.Perform an initial build of Haiku from your source directory to ensure everything compiles correctly.
2.Address any compilation errors or warnings that arise.
If you donβt need the BIOS bootloader (you use UEFI or have a BIOS bootloader from the official release installed already), you can also skip building it which means no need for a cross compiler.
I simply build jam haiku.hpkg here with a modified build target that leaves out the bootloader.
That gives a installable system package I can use to quickly test my changes.
