Re: Snort3 fails to build for armv7 hardware

Thanks Michael.  I've forwarded the patch and instructions to the pfSense
team for them to try on native ARM hardware.  I will let you know if it
works.

Hi:

 

I maintain the Snort package for the pfSense firewall distribution.  I am
currently working on a Snort3 package for pfSense.  To that end the pfSense
developers have recently enabled the build of the Snort3 binary on their
image builders.  pfSense is based on FreeBSD and is available for both AMD64
and ARMv7 architectures.  Snort3-3.0.0-255 is currently failing to build for
ARMv7 images on FreeBSD 12.  The relevant parts of the build failure log are
as follows:

This error occurs on a stock FreeBSD 12.0 installation and is not specific
to pfSense.  Could someone from the Snort3 team please take a look?

 

Thanks,

Try the attached patch.  Make sure you're building without
--enable-tsc-clock.
