Ethereal-Toolchain

Toolchain for developing with the Ethereal Operating System.

Current versions

• GCC 14.2.0
• Binutils 2.42

Preparations

WARNING: The following commands install the toolchain to your system. If you would like to avoid doing this, simply change DESTDIR.

First setup your environs:

export SYSROOT=<SYSROOT>
export ARCH=<ETHEREAL ARCH>
export DESTDIR=<DESTDIR>

Prepare a system root by cloning Ethereal. You can then use the make install-headers target to install the system headers.
Once you have done this, your SYSROOT will be in <ethereal root>/build-output/sysroot/.

Building (automatic)

Automatic building is easy. There are two scripts: build.sh and build_stage2.sh

Run build.sh and it will compile and install the first part of the toolchain.
You need to have an Ethereal installation that has already ran make headers.

Then, go back to Ethereal and run make all to compile the OS.

Now that you have done that, you can run build_stage2.sh and compile the libstdc++-v3 runtime.
This isn't necessary to build the OS but is necessary to build all the ports.

Building (manual)

Install binutils to your host computer with the following commands:

mkdir build-binutils
cd build-binutils
../binutils-2.42/configure --target=$ARCH-ethereal --prefix="/usr" --with-sysroot=$SYSROOT --disable-werror --enable-default-execstack=no
make -j4
sudo make DESTDIR=$DESTDIR install

You must have $DESTDIR/usr/bin/ in your path before compiling GCC!

Install GCC to your host computer with the following commands:

mkdir build-gcc
cd build-gcc
../gcc-12.2.0/configure --target=$ARCH-ethereal --prefix=/usr --with-sysroot=$SYSROOT  --enable-languages=c,c++ --disable-multilib --enable-threads=posix --disable-multilib --enable-shared --enable-host-shared --with-pic
make -j4 all-gcc all-target-libgcc
sudo make DESTDIR=$DESTDIR install-gcc install-target-libgcc

Now you can compile Ethereal! Do that by running make all

After you have installed the mlibc runtime, build libstdc++ with the following commands:

cd build-gcc
make -j4 all-target-libstdc++-v3
sudo make DESTDIR=$DESTDIR install-target-libstdc++-v3
