Advice to enable SCLogDebug vs SCLogConfig output
Using this link as a guide, https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Unit_Tests
It doesn't seem like the "--enable-debug" compile option enables SCLogDebug statements. In the end, I had to find and replace all of the SCLogDebug statements with SCLogConfig to see them in stream-tcp.c, I tried multiple 4.1 and 5.0 github master repos with no luck.
Not sure if the issue is with "--enable-debug" or with the instructions to set "SC_LOG_LEVEL=Debug" when starting suricata.
