i686 cross-compiler

Automated build and installation of an i686 GCC cross-compiler.

Installing the dependencies

In order to build the cross-compiler, you will need to have some packages installed in your host machine.

If you are using Arch Linux, you can run:

$ sudo ./install-deps-arch.sh

If you are using Gentoo, you can run:

$ sudo ./install-deps-gentoo.sh

If you are using Debian or Ubuntu, you can run:

$ sudo ./install-deps-debian.sh

In other systems, you will need to install the following packages to build the cross-compiler:

• gcc
• make
• bison
• flex
• gmp
• mpc
• mpfr
• texinfo

Building and installing the cross-compiler

Clone this repository, and run make.

$ git clone https://github.com/fs-os/cross-compiler
$ cd cross-compiler
$ make  # Build Binutils 2.39 and GCC 12.2.0
...

Or invoke the individual make targets.

$ make deps-binutils  # Download and extract the Binutils 2.39 source
...

$ make build-utils    # Build Binutils 2.39
...

$ make deps-gcc       # Download and extract the GCC 12.2.0 source
...

$ make build-gcc      # Build GCC 12.2.0
...

After you have built the cross compiler, you can install it with the install target. Remember to use sudo or a similar command for installing them as root. By default, the cross-compiler will be installed in /usr/local/cross/bin/, but this path can be overwritten with the PREFIX Makefile variable.

$ sudo make install  # Install Binutils 2.39 and GCC 12.2.0
...

Building and installing the i686 debugger

Optionally, you can compile the GNU debugger with a custom patch with the build-gdb target, and install it (to /usr/local/cross/bin/i686-elf-gdb) with the install-gdb target. By default, this is not build when invoking the all target.

$ make build-gdb  # For building GDB 12.1
...

$ sudo make install-gdb  # For installing it into '$PREFIX'
...
