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

["Michael R. Crusoe" <michael.r.crusoe@gmail.com>]

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\" -DGSNAP=1 -mpopcnt -DHAVE_SSE2=1 -msse2 -mno-ssse3 -mno-sse4.1 -mno-sse4.2 -mno-avx2 -g -O2 -ffile-prefix-map=/builds/med-team/gmap/debian/output/source_dir=. -fstack-protector-strong -Wformat -Werror=format-security -c -o gsnap_sse2-intersect-uint2.o `test -f 'intersect-uint2.c' || echo './'`intersect-uint2.c

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

Hi,

I admit I'm bad in such hardware internals that seem to break the
build of gmap:

intersect-uint2.c:409:21: error: incompatible types when initializing type '__m128i' using type 'int'
  409 |         __m128i p = _mm_shuffle_epi8(v_a, * (__m128i *) &(shuffle_mask16[r*16]));

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

See

for the full build log.

Any help would be welcome
