Re: [mod-security-users] Modsecurity 3 logging issues

[William C. <wil...@mu...>]

I had a similar issue with yajl and ModSec 3.0.2.
To work around, I pointed to our local build of it directly, for example
  --with-yajl=<full path to where ever>/yajl

But there is also an issue that
YAJL_LDFLAGS is not used when it builds test dir.
Work around is unwind <full path to where ever>/yajl/lib
into (CentOS) /lib64).

Hope that helps - Jay
