Re: Snort 3.1.51.0 won't compile - gettid was not declared in this scope?

["Steve Chew \(stechew\) via Snort-devel" <snort-devel () lists snort org>]

We'll have a fix out for that soon. To work around the problem, add this to src/main/analyzer.cc:

#include "utils/util.h"

Hi,



Having trouble compiling the latest Snort 3.1.51.0  on Almalinux 8.7  (I would guess the same problem happens on RHEL 
and CentOS Stream too?)



Make seems to error with :

If I simply checkout the 3.1.50.0 tag and re-run make it completes OK.



(Looks like there were some relevant commits between 3.1.50.0 and 3.1.51.0 which might have something to do with this 
error?)



Anyone have any ideas please?



Thanks,



Andrew.
