最近在搞iphone上的电子书,需要把电子书为zip格式的解压,然后在google后发现了libzzip这个库,加进工程,模拟器上编译通过,但在真机测试,报错:libzzip.a is not of required architecture.
排查很久还是不知道原因,最后问了一个大牛,他说是libzzip.a不是iphone armv6.7的使用的,要编译一个armv 6的,所以着手开始编译,困难重重.本身touchxml里面就有shell脚本,但直接编译报错:在target下面找到run script这个文件,打开,代码是这样的:
if [ -d "$SRCROOT/DONTBUILD"]; then
exit 0
fi
if [ $PLATFORM_NAME == "iphonesimulator" ]; then
TARGET=device
fi
echo $TARGET
OUTPUT_DIR="$SRCROOT/Externals/zzip/Output"
#rm -rf "$OUTPUT_DIR/*"
cd "$SRCROOT/Externals/zzip/zziplib"
$SRCROOT/Scripts/build_for_iphoneos.sh -p "$OUTPUT_DIR" "$TARGET" 2> /dev/null |
直接在bash shell中跑这段代码是跑不了的,会有一堆的错误,为把这些错去掉,就尽量简化它(a.sh)
SRCROOT="your project absolute path"
TARGET=device
OUTPUT_DIR="$SRCROOT/Externals/zzip/Output"
cd "$SRCROOT/Externals/zzip/zziplib"
$SRCROOT/Scripts/build_for_iphoneos.sh -p "$OUTPUT_DIR" "$TARGET" 2> /dev/null |
这样简化后,这个shell是可以跑出,但在这里面调用的那个build_for_iphoneos.sh这个脚本无法产生结果,也还要修改这个sh.
修改后如下:
|
# Disallow undefined variables
set -u
default_gcc_version=4.2
//iphone 3.2之前是3.1.2
default_iphoneos_version=3.2
//用与你电脑相对应的系统版本

这时开始./a.sh时候就能正确无误的产生libzzip.a的iphone版本.
