libpngのUniversal Binaryを作成 - 環境変数CFLAGSとLDFLAGSに適切な値を渡し、configureで単純にUniversal Binary

Mac Dev

CFLAGSとLDFLAGSを設定

Macintosh:libpng-1.2.12 kuru$ export CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -arch ppc"
Macintosh:libpng-1.2.12 kuru$ export LDFLAGS="-arch i386 -arch ppc"

configure

Macintosh:libpng-1.2.12 kuru$ configure --disable-dependency-tracking
