kafkacat -c -NUM semantics edge case

[edenhill]

Hey,

I can't reproduce this on latest kafkacat master (with latest librdkafka master).
What version are you on?

maglun@bib:~$ kafkacat -b localhost -q -o beginning -e -t newt2 | wc -l
100
maglun@bib:~$ kafkacat -b localhost -q -o -1000 -e -c 1000 -t newt2 | wc -l
100
maglun@bib:~$ kafkacat -b localhost -q -o -75 -e -c 1000 -t newt2 | wc -l
75

It was the 1.2 version. I just tried pulling the head from git but got
compile errors on Centos 6.

That's a librdkafka build issue, it seems to find the sasl headers but not the library.
Could you try installing the cyrus-sasl-devel and possibly cyrus-sasl-2 ?
