但是在编译时产生了很多未解决的外部错误：

$ gcc -I/opt/local/include loggertest.cpp -o loggertest -L/opt/local/lib -lboost_log-mt

编辑：我也尝试按照建议使用 clang++，但我得到了类似的错误：

编辑：按照@neverpanic

的建议通过-DBOOST_LOG_DYN_LINK编译解决

Answer 1

您遇到了标准库不匹配的问题。来自 MacPorts 的 Boost（以及来自 MacPorts 的所有其他库和自 10.9 以来的现代 OS X，我认为）是针对 clang 的 libc++ 而不是 gcc 的 libstdc++ 构建的。如果你试图混合使用这两个标准库，你将运行陷入这个问题（这是一件好事，因为如果你看不到这个，你可能会发现很难调试运行时间).

您需要使用 clang++ 而不是 gcc 来编译您的代码。或者，您可以使用 /usr/bin/g++，它现在是 clang 的符号链接。
