【Node.JS来一打C++扩展】node-gyp build失败

[hushicai]

Node.js: v6.9.4
node-gyp: 3.6.0
MacOS：10.14.5

按照书中的套路，先install头部文件，再configure生成构建文件，最后build时失败了：

gyp info it worked if it ends with ok
gyp info using [email protected]
gyp info using [email protected] | darwin | x64
gyp info spawn make
gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]
  CXX(target) Release/obj.target/first/first.o
warning: include path for stdlibc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead
      [-Wstdlibcxx-not-found]
In file included from ../first.cpp:1:

#include <utility>
         ^~~~~~~~~
1 warning and 1 error generated.
make: *** [Release/obj.target/first/first.o] Error 1

从报错信息中可知，stdlibc++头部没找着，建议用libc++。

这里有相关解决方案。

主要的问题在于：

In OS X 10.9, Apple switched from gcc to clang which results in a change in the name of the standard library name from libstdc++ (gcc) to libc++ (clang).

MacOS 10.14.5用clang，链接的c++头部应为libc++，而[email protected]链接的却是libstdc++，所以出错了。

最终解决方案：

export CXXFLAGS="-mmacosx-version-min=10.9" LDFLAGS="-mmacosx-version-min=10.9"

试了一下，[email protected]没有以上问题。
