Issue while building rdma-core package #13

Closed starnullptr closed 4 years ago

Hi, Using the rdma-core code present at https://github.com/ntrdma/rdma-core, I tried building package for Ubuntu. However, the cbuild pkg ubuntu fails with following error:

What am I missing here ? @leonidravich can you help me understand/resolve this issue.

@anubhavguleria47 not sure, but I updated the branch, please try now

starnullptr commented 4 years ago

@leonidravich sure. I will try and let you know.

Also, is it possible to run build rdma-core in-place and use it with ntrdma? If so, can you please let me know the steps for this ?

Thanks, Anubhav

@leonidravich I tried, it's still the same error. What changes have you made ?

starnullptr commented 4 years ago

@leonidravich I was able to use rdma-core in-place with ntrdma. Thanks.

@anubhavguleria47 great please share what was the solution maybe it will help to others

starnullptr commented 4 years ago

@lravich for 4.14 kernel and with current ntrdma code I didn't need to make any changes.
