glib2-devel 2.21.3: build fails with link error (needs -lresolv)

The undefined symbols are in /usr/lib/libresolv.dylib but -lresolv is not included in link command. Looks like configure fails to properly recognize the need of it (it finds res_query in /usr/lib/libc.dylib and assumes the rest are there as well -- test for functions in -lresolv is never performed).

I see it too on Tiger / PowerPC.

[dbevans (David B. Evans)]

Attached is a patch for configure.in that adds an additional test for res_9_query in -lresolv in addition to and after the existing tests for res_query. This allows this version to build on tiger ppc. Haven't tested otherwise but should work on leopard if things work as I think.

For the record, is this just a tiger ppc problem or all tiger? I assume that the existing port works OK on leopard?

FYI, this version of glib2 or better is required by latest unstable nautilus 2.27.4.

Patch for Portfile

[dbevans (David B. Evans)]

for files directory

[ryandesign (Ryan Carsten Schmidt)]

Replying to devans@…:

I have tested all four systems now, and see the problem on Tiger (PowerPC and Intel) and do not see the problem on Leopard (PowerPC or Intel).

[ryandesign (Ryan Carsten Schmidt)]

​This is the upstream bug report for this problem.

[ryandesign (Ryan Carsten Schmidt)]

Thanks for the patch. It worked for me on Tiger Intel (did not test PowerPC this time). Committed in r53885.

[ryandesign (Ryan Carsten Schmidt)]

They've fixed this upstream so glib2-devel no longer manually adds -lresolv as of r63162.
