Created attachment 404528 [details] net-dns/avahi-0.6.31-r7 config.log from Open Indiana net-dns/avahi failed to build under Gentoo Prefix on an Open Indiana system due to the expat autotools check failing to detect libexpat. This is because avahi builds as c99 and the system headers contain: /* * It is invalid to compile an XPG3, XPG4, XPG4v2, or XPG5 application * using c99. The same is true for POSIX.1-1990, POSIX.2-1992, POSIX.1b, * and POSIX.1c applications. Likewise, it is invalid to compile an XPG6 * or a POSIX.1-2001 application with anything other than a c99 or later * compiler. Therefore, we force an error in both cases. */ #if defined(_STDC_C99) && (defined(__XOPEN_OR_POSIX) && !defined(_XPG6)) #error "Compiler or options invalid for pre-UNIX 03 X/Open applications \ and pre-2001 POSIX applications" #elif !defined(_STDC_C99) && \ (defined(__XOPEN_OR_POSIX) && defined(_XPG6)) #error "Compiler or options invalid; UNIX 03 and POSIX.1-2001 applications \ require the use of c99" #endif The full file is here: https://github.com/illumos/illumos-gate/blob/master/usr/src/uts/common/sys/feature_tests.h Consequently, things failed with "Compiler or options invalid for pre-UNIX 03 X/Open applications and pre-2001 POSIX applications". Running `CPPFLAGS=-D_XPG6 emerge avahi` succeeded.
provide a patch please and pass it by avahi upstream. i get what you're up to but i would rather not support extra patches especially when need for standards compliance.
You can report it here: https://github.com/lathiat/avahi/issues/new Thanks
(In reply to Richard Yao from comment #0) Richard, are you planning on doing anything with this bug? While I like to support prefix its not something I can easily do because I don't have a test env. Can you at least open a bug report upstream else I'll just close this wontfix. I can't speak to the details of what you're hitting.
