Aaron T. Myers commented on HDFS-4484:
--------------------------------------
The patch looks good to me. I confirmed that on gcc 4.6.3 libwebhdfs does not
compile without this patch, and does compile with it.
To test this I also had to install libcurl4-openssl-dev and libjansson-dev to
get this to compile at all, neither of which is documented in BUILDING.txt.
Colin, mind documenting those dependencies in BUILDING.txt as well? This could
be done as a separate JIRA if you'd prefer. Either way is fine by me.
