我遇到了链接库的问题。

我通过 brew 安装了它的一个版本，但后来我发现我需要在构建中添加环境标志：

CXXFLAGS="-stdlib=libstdc++ -mmacosx-version-min=10.6" \
            LDFLAGS="-stdlib=libstdc++ -mmacosx-version-min=10.6"

所以我在 opt/local/lib 安装了另一个使用标志构建的版本。我的问题是操作系统仍在使用 brew 安装版本。我已经搜索但无法找到如何将 os 链接到正确构建的库或使用标志构建 brew 版本。

我认为这是问题的原因是，在为 ruby​​ 构建 quantlib-swig 时，我收到以下错误，一些论坛称这些错误与环境标志有关：

关于问题的后半部分，如何使用标志构建 brew 版本，您可以使用ENV.appendinstall 函数在 OSX 上构建 quantlib homebrew 配方：

def install
  ...
  if MacOS.version >= :mavericks && ENV.compiler == :clang
    ENV.append "CXXFLAGS", "-stdlib=libstdc++ -mmacosx-version-min=10.6"
    ENV.append "LDFLAGS", "-stdlib=libstdc++ -mmacosx-version-min=10.6"
  end
  ...
  system "make", "install"
end
