[Unbound-users] solaris 10 sun studio 12 build failure

Hi Nathan,

Thanks for trying unbound.

Unbound compiles cleanly and is known to work on Solaris 9, 10 and 11,
using gcc compilers.

You are using the sun compiler and hence the errors.

So far for the audience, about your problems:
the code is from the part that uses the cmsghdr structure to send
ancillary information using sockets. This probably needs -D_EXTENSIONS_
and whatnot to get on Solaris. The detection for what -D... flags are
needed works well on gcc, but not on sun-cc I guess. This is because it
tries -std=c99, but that is really -xc99 I see on your system.

Can you try to pass
CC="cc -xc99 -D__EXTENSIONS__ -D_BSD_SOURCE -D_POSIX_C_SOURCE=200112
- -D_XOPEN_SOURCE=600 -D_XOPEN_SOURCE_EXTENDED=1 -D_ALL_SOURCE"

this enables all of them. not pretty. Can you send me your config.log
(offlist please, its pretty big) and perhaps your configure output,
maybe this can be fixed.

Maybe with proper system header definitions the improper assignment
errors go away as types are declared.

Best regards,
~   Wouter

| The type mismatches are easy to fix, but those undefined struct/union

|
| 2) During configure, it would try to build ldns, as ldns was not
