c++ - ubuntu14.04上编译caffe-1.0时opencv报错

Question

我在用opencv编译最新的caffe-1.0时遇到了一个bug。
我在 ubuntu14.04 上使用 gcc-4.8.5 与 cuda8.0 和 cudnn5.1 编译它。
我尝试了不同版本的 opencv(2.4.8, 2.4.13, 3.2.0) 但错误仍然存​​在。
错误如下:

/usr/include/opencv2/core/core.hpp:4127:9: error: expected identifier before ‘float’
FLOAT=REAL, //!< synonym or REAL
^
/usr/include/opencv2/core/core.hpp:4127:9: error: expected ‘}’ before ‘float’

我自己解决了这个问题。

出现这个错误是因为我编译安装了最新的OpenBlas库，版本0.2.19。文件 cblas.h 导致 opencv 问题。

我刚刚重命名了/usr/local/include 中的 cblas.h，所以命令 make 将使用/usr/include 中的 cblas.h 并最终成功。
