Question

我刚刚从Yosemite更新到El Capitan，它打破了我的一个依赖Boost的C ++程序。每当我尝试编译时，我都会遇到这些错误：

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"

我一直用正确的标志编译它，之前它完美地工作：

-lboost_timer-mt \
-lboost_program_options-mt \

我按照家庭酿造说明chown / usr / local，运行brew doctor和brew更新，甚至酿造重新安装提升。我还检查了/ usr / local / include / boost中的timer.hpp。

更新 Ran：clang ++ -E -x c ++ - -v＆lt;的/ dev / null的

您应该使用{{1}}安装Xcode命令行工具，以获取默认情况下搜索/ usr / local的clang版本。否则，您正在使用Xcode提供的版本，该版本仅搜索OS X SDK路径。（/ usr / bin / gcc和/ usr / bin / g ++都调用clang并且实际上不是gcc的版本。）

当我升级到El Capitan时，我遇到了同样的问题。我解决了这个问题，用brew重新安装Boost。

如果您没有安装brew，可以使用

进行安装

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

然后，安装boost

brew install boost

在Mac El Capitan上，Boost不再适用于Homebrew
