构建Caffe时对boost :: thread函数的未定义引用

Question

我试图在Ubuntu 14.04上编译Caffe。我一直在链接阶段遇到undefined reference to 'boost::thread::...'错误。

我搜索了网络，发现很多人有类似的问题，并尝试了我发现的所有内容（这里列出的内容太多了）。

我尝试使用apt-get安装boost：

• sudo apt-get install libboost-python-dev
• sudo apt-get install libboost-all-dev

还尝试从源代码构建和安装：

• sudo ./b2 --threading = multi -j4 --with-thread install
• sudo ./b2 --threading = multi -j4 --with-thread install -a link = static

我一直在犯的错误是：
