在 Mac El Capitan 上，Boost 不再与 Homebrew 一起使用

Question

我刚刚从 Yosemite 更新到 El Capitan，它破坏了我的一个依赖 Boost 的 C++ 程序。每当我尝试编译时，我都会收到这些错误：

fatal error: 'boost/timer/timer.hpp' file not found
#include <boost/timer/timer.hpp>

fatal error: 'boost/program_options.hpp' file not found
#include "boost/program_options.hpp"

我一直在用正确的标志编译它并且它之前工作得很好:

-lboost_timer-mt \
-lboost_program_options-mt \

我已经按照自制软件的说明进行了 chown /usr/local、运行 brew doctor 和 brew update，甚至 brew reinstall boost。我也检查过 timer.hpp 存在于 /usr/local/include/boost.

更新运行: clang++ -E -x c++ - -v < /dev/null

Answer 1

我升级到 El Capitan 时遇到了同样的问题。我用 brew 重新安装 Boost 解决了这个问题。

如果你没有安装brew，你可以用

安装它

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

然后，安装 boost

brew install boost

Answer 2

您应该使用 xcode-select --install 安装 Xcode 命令行工具，以获得默认搜索 /usr/local 的 clang 版本。否则，您使用的是 Xcode 提供的版本，它只搜索 OS X SDK 路径。（/usr/bin/gcc 和 /usr/bin/g++ 都调用 clang 而不是 gcc 的实际版本。）
