Snort3 fails to build for armv7 hardware

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:

 

/nxb-bin/usr/bin/c++  -DHAVE_CONFIG_H -Dinline=inline -Drestrict=__restrict
-I/wrkdirs/usr/ports/security/snort3/work/snort3-3.0.0-255/src/network_inspe
ctors

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,
