Item4220: Native search on Solaris

Priority:	CurrentState:	AppliesTo:	Component:	WaitingFor:
Low	New	Engine	SEARCH, NativeSearchContrib	TWiki:Main.AaronPeterson

With modifications I got this working:

Platform	Perl Version	Accelerator	Whodunnit
SunOS 5.10	5.8.7	mod_perl	AaronPeterson

Sun's libc doesn't have getline like GNU's does, so I linked in the gettext library where I found one, as installed by http://sunfreeware.com/programlistintel10.html#gettext. I added the gettextlib library to Makefile.PL:

   LIBS => [ "-lgettextlib -lpcre" ],

...and needed a couple of cheap preprocessor stanzas in cgrep.c:

Good work, Aaron, thanks. But doesn't the addition of -lgettextlib to Makefile.PL mean that platforms that do have getline are now going to require an unneccesary dependency, causing ld to barf unneccesarily if it's missing? It might be easier just to provide a version of getline in this source file.

the addition of libs that are not installed or needed only produce a warning when running perl Makefile.PL, otherwise are fine.

However, the #if OSNAME = solaris= seems to evaluate to true on my debian.

Worse, is this the only solution for all solaris versions?

Obviously Aaron is not going to provide feedback.

Lowering to Low priority.
