我从 Sourceforge 下载了 Qauntlib-SWIG v1.9，还尝试了 githubmaster分支，按照官方页面上的说明进行操作，但在这两种情况下，我都会收到以下错误消息。

我正在运行MacOS Sierra//版本Python 3.61.64.0_1 boost，gcc版本低于。我安装了quantlibv1.9.2 与Homebrew.

$ gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin16.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

我怀疑该错误是由以下第一条语句引起的：python -c++ ...它似乎不是 python 的有效标志，它给出了错误消息（python -c++在命令提示符下尝试，得到相同的错误）。

知道这个标志是如何/从哪里来的吗？谢谢你。

弄清楚为什么会这样。Grepped Makefile。如果事实上它正在寻找 SWIG。所以brew install swig解决了这个问题。

虽然官方安装网页上说swig不是必须的，但最后还是需要的。
