cannot find -lcudnn

[bcd33bcd]

When I configure marvin , the error confuse me .

/usr/bin/ld: skipping incompatible /usr/local/cudnn/v5/lib64/libcudnn.so when searching for -lcudnn
/usr/bin/ld: cannot find -lcudnn
collect2: error: ld returned 1 exit status

If ld cannot find -lcudnn, there is 3 possibility.

1. libcudnn do not install
2. libcudnn version not right
3. libcudnn.so link configure error.

I try the v4,v5 version of cudnn ,but not working.

1. confirm the path of your cudnn is right
2. add the cudnn to the LD_LIBRARY in the environment
3. the most import, the permission of your file might be 755, use chmod 755 xxx to change the User authorization or something of cudnn and its sub-files. Because, when you copy, maybe you lost the User authorization or something. use ls -l to check the soft link.

• May it help.

This is what I did to solve the problem:
sudo cp -r /home/jalal/cudnn/cuda/lib64/* /usr/local/cuda/lib64
