Re: [Help] Could someone please have a look at gmap build failure

The real error is at

gcc -DHAVE_CONFIG_H -I.   -Wdate-time -D_FORTIFY_SOURCE=2
-DTARGET=\"x86_64-pc-linux-gnu\" -DGMAPDB=\"/var/cache/gmap\"

-fstack-protector-strong -Wformat -Werror=format-security -c -o
gsnap_sse2-intersect-uint2.o `test -f 'intersect-uint2.c' || echo

intersect-simd.c: In function 'v1':

      |        ^~~~~~~~~~~~~~~

I don't think upstream tested the SSE2 build recently; I'm looking at this now
