How to compile Haiku on Haiku?

You supposed to use the crosscompiler on 64 bit from the buildtools repo.

This is due to the 32-bit BIOS bootloader needing the full cross-tools to be built, and as of now it’s still included in haiku.hpkg (though that may change.) You can get around this by commenting out line 31 in build/jam/packages/Haiku.

Got it, cross-compile on 64-bit for optional 32-bit BIOS bootloader. I suppose then a 64-bit compiler can’t generate 32-bit code? Seems odd, given the -m32 flag in gcc.

../haiku/configure --update

I assume this still works even if compiling from Haiku? I did try that without effect

I’ve faced the same kind of errors and solved them by pulling latest buildtools code and rebuilding it (rm -r cross-tools-x86_64 before running ../configure --update).

Gcc can do it, but the haikuports recipe isn’t written correctly, so the version of gcc from the hpkg file can’t.

It would be great if someone fixed that recipe.

The HaikuPorts GCC can do it just fine; but the recipe doesn’t build the 32-bit bootloader libgcc, so the resulting binaries can’t be linked.
