编译libcurl iOS

首先设定环境变量：

真机：

export IPHONEOS_DEPLOYMENT_TARGET="4.3"
export CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-4.2"
export CFLAGS="-arch armv7 -arch armv7s -pipe -Os -gdwarf-2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk"
export LDFLAGS="-arch armv7 -arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk"
./configure --disable-shared --enable-static --disable-dependency-tracking --host="armv7-apple-darwin"

模拟器：

export IPHONEOS_DEPLOYMENT_TARGET="4.3"
export CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2"
export CFLAGS="-arch i386 -pipe -Os -gdwarf-2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk"
export CPPFLAGS="-D__IPHONE_OS_VERSION_MIN_REQUIRED=${IPHONEOS_DEPLOYMENT_TARGET%%.*}0000"
export LDFLAGS="-arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk"
./configure --disable-shared --enable-static --host="i386-apple-darwin" 

 

编译：
a)  打开Xcode选择: File->New Project->iOS->Library->Cocoa Touch Static Library
添加文件:Add->Existing Files (选择curl中 "src"文件夹),Add->Existing Files (选择curl中 "lib"文件夹)

删除文件:从项目中删除 "src/macos" 文件夹(Delete->Delete references)，并且去掉Makefile and Makefile.inc（共四个，src和lib中各两个）的”target”标志。（注意是在project中操作，不是在target中操作）
 
b)  打开“build”选项，查找OTHER_C_FLAGS设置下面信息
-DHAVE_CONFIG_H -I/ca/dev/code/lib/curl/curl-latest/include -I/ca/dev/code/lib/curl/curl-latest/lib

说明： /ca/dev/code/lib/curl/curl-latest就是刚才解压curl源代码的路径，在本机中是
-DHAVE_CONFIG_H -I/libcurl/curl/include -I/libcurl/curl/include/lib

 

然后直接利用Xcode编译就可以得到静态库文件。
