Gif native capability has been completely upgraded to allow for reading and writing the gif format
in singles, sequences or lists. As a side effect of this effort all of the other sequences have had the
letter “s” added at the end of the extension filename automatically generated on a render.
due to giflib-5.2.2.patch2I removed patch and build is ok. Not sure where this patch was needed, may be on older distros?I also tried to "set -e" before building cingg and get build breaking error somewhere in x265 dir, as reported already.but for me default (seen with "set -o" ) errexit=off, you can set it off for specific build by executing "set +e" before building cingg.
