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.
