cmake 使用了错误的 cboost 库

Question

我尝试用 cmake 编译一个程序，但我收到了这个错误：

  Unable to find the requested Boost libraries.

  Boost version: 1.34.1

  Boost include path: /usr/include

  Detected version of Boost is too old.  Requested version was 1.37 (or
  newer).

  The following Boost libraries could not be found:

          boost_program_options
          boost_filesystem

  No Boost libraries were found.  You may need to set Boost_LIBRARYDIR to the
  directory containing Boost libraries or BOOST_ROOT to the location of
  Boost.

我已经在 /home/dev/boost_1_45_0 下安装了新的 boost 包。

但是当我再次尝试运行 cmake 时，我仍然会遇到同样的错误。

我也设置了

export BOOST_ROOT=/home/dev/boost_1_45_0

但是当我执行cd ${BOOST_ROOT} 时，我在正确的文件夹中。

有人可以帮我吗？谢谢！

尝试删除你的构建树，然后运行：

cmake -DBOOST_ROOT=/home/dev/boost_1_45_0 path/to/src path/to/build
