Visual Diff reports are empty

[kranthim84]

hi, I am using 1.8 version and I am trying to compare jar files with the following options -check-byte-code -full-method-diffs

The main report shows the % change in the changed Java Classes. However, if I click on the link "diff" , it redirects me to a blank page. The HTML files are created for each of the Changed classes but they are empty.

Can you please advise what could be the reason?

BTW, I get a following warning when I run the tool WARNING: perl-File-LibMagic is not installed I think, this should not be the reason for the empty reports.

Please help.

I have figured out the reason by adding Debugs in rfcdiff shell script.

Reason: The awk version is I was using is not compatible with rfcdiff. I had to install GNU Awk to make the class level diff reports working.

Although you closed this, I'm wondering if it's worth doing some version checking so a helpful error message would be generated instead of unexpected behavior.

hi @hobbes1069 , True. A helpful error, would save a lot of time.

On MacOS, Install gawk use brew install gawk.

Installing gawk is not solving the issue for me :(
