Modern Compilers for PowerPC Mac OS X Tiger & Leopard

GCC 7, GCC 10, and Perl 5.34 - Prebuilt for PowerPC G4/G5!

Run modern compilers on your vintage Mac. No cross-compiling needed - these are native PowerPC binaries.

What's Included

Package	Version	ppc32 (G4/Tiger)	ppc64 (G5/Leopard)
GCC	7.5.0	gcc7-7.5.0-tiger-ppc32.tar.gz	gcc7-7.5.0-tiger-ppc.tar.gz
GCC	10.5.0	-	gcc10-10.5.0-tiger-ppc.tar.gz
Python	3.7.17	python3.7-tiger-ppc32.tar.gz	-
Perl	5.34.3	perl5-5.34-tiger-ppc.tar.gz	-

Why You Need This

Mac OS X Tiger (10.4) and Leopard (10.5) ship with:

• GCC 4.0 (Tiger) / GCC 4.2 (Leopard) - Too old for modern code
• Perl 5.8 - Missing modern Perl features

These compilers let you build:

• Modern C++11/14/17 code
• Software requiring GCC 7+
• Perl scripts using modern features
• Node.js, Python extensions, and more

Installation

GCC 7.5.0

cd gcc7
tar xzf gcc-7.5.0-ppc-tiger.tar.gz
sudo mv gcc-7.5.0 /usr/local/
export PATH=/usr/local/gcc-7.5.0/bin:$PATH

GCC 10.5.0

cd gcc10
tar xzf gcc-10.5.0-ppc-leopard.tar.gz
sudo mv gcc-10.5.0 /usr/local/
export PATH=/usr/local/gcc-10.5.0/bin:$PATH

Perl 5.34.3

cd perl5
tar xzf perl-5.34.3-ppc.tar.gz
sudo mv perl-5.34.3 /usr/local/
export PATH=/usr/local/perl-5.34.3/bin:$PATH

Verification

# Check GCC version
gcc --version
# gcc (GCC) 7.5.0 or 10.5.0

# Check Perl version
perl -v
# This is perl 5, version 34, subversion 3

# Test C++17 features (GCC 7+)
echo 'int main() { auto x = [](auto a) { return a; }; }' | gcc -std=c++17 -x c++ -

Building From Source

If you want to build these yourself:

GCC Bootstrap

# On Leopard with Xcode 3.1 (GCC 4.2)
cd gcc-7.5.0
./contrib/download_prerequisites
mkdir build && cd build
../configure --prefix=/usr/local/gcc-7.5.0 \
    --enable-languages=c,c++ \
    --disable-multilib
make -j2 bootstrap
sudo make install

Prerequisites

• Xcode 2.5 (Tiger) or Xcode 3.1 (Leopard)
• At least 2GB RAM
• 5GB free disk space
• Patience (bootstrap takes 4-8 hours)

GNU tar	1.30	tools/tar-1.30-tiger-ppc32.tar.gz

Modern tar with xz/lzma support - Tiger's tar 1.14 is too old for modern archives.
