xcode - 如何在 MacOS10.12 下安装 libcurl 并用于 Xcode？

Question

Building libCURL for iOS 4.2

大家好:
这是我的第一个堆栈溢出问题。我已经阅读了之前发布的博客，但我仍然无法完成构建。我对终端编程不熟悉。首先让我向您展示一些关于我的 mac 上 xcode 的基本信息。

`Wuqians-MBP:~ wuqianzhong$ xcode-select -p
/Applications/Xcode.app/Contents/Developer
Wuqians-MBP:~ wuqianzhong$ g++ -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.3.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin`

然后我输入了从博客Building libCURL for iOS 4.2.中学到的以下4行

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

export CFLAGS="-arch x86_64 -pipe -Os -gdwarf-2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Deveoper/SDKs/iPhoneOS10.2.sdk"

export LDFLAGS="-arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS10.2.sdk"

 ./configure --host=x86_64-apple-darwin --with-zlib --disable-shared --enable-static --disable-ipv6 --disable-manual --disable-verbose 

但是，结果表明我没有正确构建。甚至 C 编译器也不工作。

How to install libcurl in Mac
嘿，我想我已经找到了答案并且它有效!

下载curl安装包并解压

使用终端进入curl安装包文件夹根目录

设置安装路径:./configure --prefix=/usr/local/curl

编译:make

安装:sudo make install

然后你会在路径/usr/local/curl 中发现 curl 有四个文件
bin、包含、lib、共享。
