Hi,
I'm trying to experiment with lepton for my software portability class, however when I try to run lepton on one of my class servers I get these errors:

src/io/seccomp-bpf.hh:61:3: warning: #warning "Platform does not support seccomp filter yet" [-Wcpp]
src/io/Seccomp.cc:58:4: error: #error "AUDIT_ARCH value unavailable"
/# error "AUDIT_ARCH value unavailable"
^~~~~

and

src/lepton/jpgcoder.cc: In function ‘int app_main(int, char**)’:
src/lepton/jpgcoder.cc:855:13: error: ‘__builtin_cpu_supports’ was not declared in this scope
__builtin_cpu_supports( "avx2" )
I'm compiling with the option you gave inissue 71.

Is there any advice you can give?

Thank you,
Sanjit
