Install gcc

Installing gcc is simple: you just need to have a working gcc and compile the sources...

Prerequisites

A compiled version of gcc is provided by SourceForge's High Performance Scientific Computation on Mac OS X project.

Alternate Location: http://ftp.heanet.ie/disk1/disk1/sourceforge/h/project/hp/hpc/OldFiles/gcc-intel-bin.tar.gz

Note: Do not get the binary package gcc-tiger-bin.tar.gz. That is for the PPC, not Intel.

We'll also need some binaries from an Intel Mac with Tiger and Xcode tools install.

Prepare the install

The files will be installed in /usr/local/. In order not to take too much space in the smaller OSBoot partition, we'll have this directory on the Media partition.

Log into the AppleTV as root and create the directory:

mkdir /mnt/Scratch/local

If you already have a /usr/local/ directory, move it:

cp -R /usr/local/* /mnt/Scratch/local/
rm -R /usr/local

Now make a link to it:

ln -s /mnt/Scratch/local /usr/local

Install the binaries

Navigate to the directory where you downloaded gcc-intel-bin.tar.gz and uncompress it:

tar -xvzpf gcc-intel-bin.tar.gz -C /

Make a link to gcc:

ln -s /usr/local/bin/gcc /usr/bin/cc

Test it:

cc -v

From an Intel Mac with Tiger with Xcode tools installed, copy to the following files to AppleTV:

/usr/bin/as
/usr/bin/ld
/usr/bin/make
/usr/lib/bundle1.o
/usr/lib/crt1.o
/usr/lib/dylib1.o
/usr/lib/gcrt1.o
/usr/libexec/gcc/darwin/i386/as

From the same Mac, copy the directory /usr/include to the AppleTV's /usr/local/include.

Optional files to copy:

/usr/bin/ar
/usr/bin/basename
/usr/bin/libtool
/usr/bin/uniq

And:

ln -s /usr/bin/libtool /usr/bin/ranlib
ln -s /usr/local/bin/g++ /usr/bin/g++
ln -s /usr/local/bin/cpp /usr/bin/cpp
ln -s /usr/local/bin/gcc /usr/bin/gcc

Test a first compilation:

echo 'int main () { return 0; }' > /tmp/test.c
cc /tmp/test.c
