compile qt source code (0) - mac osX 10.4 ppc/intel

20100323 新增
qt-everywhere-opensource-src-4.6.2.tar.gz

OS: mac osX 10.4 powerpc

gcc/g++ version: powerpc-apple-darwin8-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5564)

mac osX 10.4 只能使用 xcode 2.5, 不能用 xcode 3.X
用 xcode 的 gcc 4.0.1 會有 internal error 的怪問題。

所以需要 gcc 4.2.1 的版本。
gcc/g++ 4.2.1 請到以下 url 下載:
http://r.research.att.com/tools/#gcc42
太神奇了, 這竟然是 ppc/intel 都可以用的版本。
macds:~/usr/bin descent$ file gcc-4.2
gcc-4.2: Mach-O universal binary with 2 architectures
gcc-4.2 (for architecture i386): Mach-O executable i386
gcc-4.2 (for architecture ppc): Mach-O executable ppc

./configure -no-qt3support
make

You maybe get the error message

可以用 mac port 安裝 qt4

sudo port install qt4-mac

可能也會遇到類似的問題, 可參考 ref: http://trac.macports.org/ticket/23284

Old part:

wget ftp://ftp.trolltech.com/qt/source/qt-mac-opensource-src-.4.3.tar.bz2

目前抓的是這版, 是 mac 的版本, X, ms windows, 都是一樣的編譯方式。

tar jxvf qt-mac-opensource-src-.4.3.tar.bz2

由於我不想編譯 qt3 的相容部份, 所以使用下面的參數, 這樣比較快。

./configure -no-qt3support
make

即可。 mac 版本有提供 precompile 版本, 就不用自己編譯了, 因為編譯 qt 空間要佔不少,
時間也要很久。

在我的 mac mini core duo 2.33 2g ram 上, 花費的時間。
不編譯 qt3 相容 library。

這是使用 usb 外接硬碟, 看來 intel core duo 2.33 效能贏很多阿！
