我使用的是具有GCC 4.6的Ubuntu 12.04，但我的项目需要C ++ 11，因此我使用https://askubuntu.com/a/271561安装4.8，一切似乎都有效，我可以编译我的代码。< / p>
$ g++ --version
g++ (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1
我还从网页下载了boost 1.55并使用它构建了它。
./bootstrap.sh
./b2
sudo ./b2 install
一切正常，它似乎是为gcc 4.8而构建的。但是当我尝试链接我的项目时，我得到链接器错误以提升：

我首先使用旧版本构建了boost，但在看到这可能与正在使用的不同编译器版本有关后，我删除了boost文件夹，再次提取源并从头开始构建所有内容，重建我的代码但我仍然得到了同样的错误。
更新： 这是我得到的结果＆＃39; VERBOSE = 1 make＆＃39;，我使用CMake来构建项目。

更新：
从apt-get中删除boost 1.46后我得到了这个错误
Linking CXX executable server
/usr/local/lib/libboost_thread.a(thread.o): In function `boost::this_thread::hiden::sleep_for(timespec const&)':
thread.cpp:(.text+0x1290): undefined reference to `clock_gettime'
似乎应该通过链接器标志中已包含的-lrt标志来解决。
答案 0 :(得分：1)
将-lrt添加到链接行的末尾以解决问题w / clock_gettime()
