[Opendnssec-develop] building on OS X (SUPPORT-86)

[John Dickinson]

Hi,

This applies to trunk and the 1.4 branch. Seems like things are weird on OS X.

./configure CFLAGS=“-D_POSIX_C_SOURCE” works (well it builds at least).

However editing configure.ac and adding (to the darwin target-specific stuff)

Index: configure.ac
===================================================================
--- configure.ac	(revision 7426)

requires _DARWIN_C_SOURCE to work. If you use _POSIX_C_SOURCE (or nothing) you get the following build error:

2 errors generated.

BTW:

        #  ifndef _POSIX_C_SOURCE
        #    define _POSIX_C_SOURCE 200112
        #  endif

is in the the AH_BOTTOM clause. Should that be 200112L to be consistent with the _XOPEN_SOURCE 600???

Any ideas?

This was tested on Mavericks.
