在Mac El Capitan上,Boost不再适用于Homebrew

Question

我刚从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,我都会遇到以下错误:

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.我也检查了/ usr/local/include/boost中的timer.hpp.

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

您应该安装Xcode命令行工具xcode-select --install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而不是gcc的实际版本.)
