#64629: Update needed for mac m1 max
--------------------+-----------------------
 Reporter:  SiggyF  |      Owner:  (none)
     Type:  update  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.7.1
 Keywords:          |       Port:  protozero
--------------------+-----------------------
 This ports needs an update to 1.7.1 to get working with m1 mac, as
 described in https://github.com/mapbox/protozero/issues/107.
 There is also another issue, which I could fix by editing the cmake
 settings. The problem is that by default `-werror` is used combined with
 -std=c++11.
 {{{
 /opt/local/include/google/protobuf/parse_context.h:365:3: error: use of
 the 'nodiscard' attribute is a C++17 extension
 [-Werror,-Wc++17-extensions]
   PROTOBUF_NODISCARD const char* AppendString(const char* ptr,
 }}}
 If I set `WERROR:BOOL=OFF` the build completes with clang++ . Another
 option would be to change the -std=c++11 to -std=c++17, but I could not
 find where to put that in the cmake settings.
