这个问题之前没有，今天晚上刚出现。

make过程如下：
cmake .. -DRDMA_ROOT=/root/pp/sxi_for_mlnx -DMKL_ROOT=/opt/intel17/compilers_and_libraries_2017.0.098/linux/mkl -DWITH_DOC=ON -DWITH_GPU=ON -DWITH_AVX=ON -DWITH_RDMA=ON -DWITH_PROFILER=ON
make install

崩在：

简单检查一下librdma：
[root@g4 function]# ll /root/pp/git/paddle/build/paddle/function/librdma/
total 0
lrwxrwxrwx 1 root root 30 Mar 26 11:22 libibverbs.so -> /usr/lib64/libibverbs.so.1.0.0
lrwxrwxrwx 1 root root 30 Mar 26 11:22 libibverbs.so.1 -> /usr/lib64/libibverbs.so.1.0.0
lrwxrwxrwx 1 root root 29 Mar 26 11:22 librdmacm.so -> /usr/lib64/librdmacm.so.1.0.0
lrwxrwxrwx 1 root root 29 Mar 26 11:22 librdmacm.so.1 -> /usr/lib64/librdmacm.so.1.0.0
能看到有librdma

这时候，就不知道linker说的那个c++: error: ./librdma: No such file or directory指的是什么了，也不知道怎么找原因。

版本：
[root@g4 build]# git show

Merge pull request #1702 from gangliao/python_remove

Fix NOT WITH_PYTHON

另外请教一下，看版本是不是git show git log？
