*** Error code 1
make: Fatal error: Command failed for target `Interface.o'
I did not see this failure on an earlier OpenIndiana with perl 5.38 built with gcc-13; this behavior appears to be new with gcc 14 and could potentially affect other platforms.
I patched around it by adding #include <strings.h> to Interface.xs.
Looking upstream in CPAN, there is now an IO::Interface 1.09 which adds an include of <string.h> but that doesn't have bzero on illumos (I believe XPG expects it it in <strings.h>); it also doesn't build as-is on OpenIndiana either with the same error.
It would seem most appropriate to replace bzero(x,y) with the more-portable memset(x,0,y).
Will happily provide a pull request but I'm new to LMS -- not sure what this project's preferences are in terms of tracking newer versions in CPAN, etc.,
