=MacPorts GCC 4.9 Binary Installer For PowerPC Mac OS X Tiger
Put together by Alex Free. Release 1, 11/25/2020.
=Background
GNU GCC 4.9 requires many dependencies and bootstrap compilers when
compiling completely from source using MacPorts for PowerPC Mac OS X
10.4 Tiger. All together, compiling this can easily take a day or 2.
This installer on the other hand takes just under 2 hours on my Mac to
install everything. Essentially, the installer temporarily changes the
MacPorts configuration files to use a local source for obtaining the
ports tree and binary archives. After doing so, the ports tree is
synced, binaries are installed, all changes are reverted, and finally
the ports tree is synced with MacPorts proper. Your system remains
untouched, besides the addition of the new compiler and it's
dependencies.
=Disclaimer
\- The following MacPorts ports will be automatically uninstalled if
they are found to be installed:
This is because this installer will install them. At the end of the
install, 'port sync' will also be run, updating your ports tree.
=Requirements
\- Mac OS X 10.4.11 PowerPC (Should also work on Leopard, and be able
to compile for Tiger from Leopard).
\- Xcode 2.5 (The last Xcode released for Tiger, although nothing will
be compiled).
\- MacPorts 2.0.0 or newer installed.
=Steps
\- Open Terminal.app.
\- Using sudo, execute the 'install' file in this release ('sudo
/install').
\- Wait (Took 2 hours on my Mac mini).
When done, you can select your GCC 4.9 compiler using the command
'sudo port select --set gcc mp-gcc49'. Then, you can check with the
command 'gcc --version'.
