To compile Xelix, you first need the Xelix toolchain. It consists of binutils, a GCC cross-compiler and the newlib C standard library, all with configuration and patches to support the i786-pc-xelix target.
You can build the toolchain using
make -C toolchain
Depending on your hardware, this will take a significant amount of time.
Once it is done, you should find Xelix-specific binaries of GCC, g++, ld, etc. in
toolchain/local/bin. I find it convenient to add that directory to
PATH, but the Xelix Makefile will also work without doing so.
i786-pc-xelix-g++ from that directory can also be used to compile userspace binaries and automatically include the correct standard library, linker script and crt0:
# Can be used like regular GCC i786-pc-xelix-gcc test.c -o test
In addition to the toolchain, the NASM assembler also needs to be installed.
Once you have that in place, you can compile Xelix using:
1 2 3
make gconfig ./configure make
You should now see a binary called
xelix.bin. 🎉 Place it in the
/boot directory of your Xelix installation and reboot (Note that
/boot may be on a separate partition).
