automake / autoconf newbie here. I have a package that isn't currently
being built with _GNU_SOURCE defined and is running into compile
problems when a portion of it attempts to access hostent->h_addr.
If I compile with -D_GNU_SOURCE all is well, but I want to get this
fixed correctly upstream. What is the proper / preferred way to do
this? I see a couple options:
- Get it added to acinclude.m4 and it will show up somewhere in a
header file(?)
- Modify configure.ac (or other) to generage a configure.in that
tacks it onto DEFS which shows up then as DEFS in configure and
populates DEFS in the resultant Makefile so we have -D_GNU_SOURCE
passed to the compiler
What other ways are there to do this and what's the preferred way?
I'll answer my own question if I find the answer in the automake /
autoconf docs. :)
