[操作系统]Mac OS X环境下源代码编译libcurl


转载请注明出处,否则追求责任

在进行libcurl的源码编译之中,参照官方文档和google搜索出来的总是编译失败,索性根据提示的失败一步一步查出原因,说白了,就是OS X缺少gnu的几个工具,还需要初始化config才行,libcurl官方根本没提及,ok,那就自己搞定。

首先,需要安装autoconf和automake工具

1)安装m4

http://www.gnu.org/software/m4/

tar -xzvf m4-1.4.17.tar.gz

cd m4-1.4.17

./configure --prefix=/usr/local

make

sudo make install

 

2)安装autoconf

http://www.gnu.org/software/autoconf/

tar -xzvf autoconf-2.69.tar.gz

cd autoconf-2.69

./configure --prefix=/usr/local

make

sudo make install

 

3)安装automake

http://www.gnu.org/software/automake/

tar xzvf automake-1.14.tar.gz

cd automake-1.14

./configure --prefix=/usr/local

make

sudo make install

 

4)安装libtool

http://www.gnu.org/software/libtool/

tar xzvf libtool-2.4.2.tar.gz

cd libtool-2.4.2

./configure --prefix=/usr/local

make

sudo make install

 

5)下载libcurl源码,运行libcurl初始化脚本

git clone https://github.com/bagder/curl.git

cd curl

./buildconf

 

6)编译simulator版本,首先需要设置诸多编译环境,本人mac环境是xcode 6.4, sdk是8.4为例

export IPHONEOS_DEPLOYMENT_TARGET="8.4"

export CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"

export CFLAGS="-arch i386 -pipe -Os -gdwarf-2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.4.sdk"

export LDFLAGS="-arch i386 –isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.4.sdk"

./configure --disable-shared --enable-static --host="i386-apple-darwin" --prefix=/usr/local --with-darwinssl --enable-threaded-resolver

make -j `sysctl -n hw.logicalcpu_max

cp lib/.libs/libcurl.a ~/Desktop/libcurl-i386.a

make clean

 

7)编译arm版本稍有不同

export IPHONEOS_DEPLOYMENT_TARGET="8.4"

$ export CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"

$ export CFLAGS="-arch [ARCH] -pipe -Os -gdwarf-2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.4.sdk"

$ export LDFLAGS="-arch [ARCH] -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.4.sdk"

$ ./configure --disable-shared --enable-static --host="[ARCH]-apple-darwin" --prefix=/usr/local --with-darwinssl --enable-threaded-resolver

$ make -j `sysctl -n hw.logicalcpu_max`

cp lib/.libs/libcurl.a ~/Desktop/libcurl-[ARCH].a

make clean

此处特别注意[ARCH]代表armv7,armvs7和arm64,但是[ARCH]-apple-darwin这里却不存在arm64-apple-darwin,需要改成arm-apple-darwin即可config通过。

 

8)合并libcurl

cd ~/Desktop

$ lipo -create -output libcurl.a libcurl*
