Greetings
First, I'd like to apologize upfront for the sheer autoconf noob-ness
this post might impose on vets possibly on this list. But as luck
would have it, I seem to be stuck with the job of dealing with an
autoconf.ac script of ours wich doesn't seem to want to play nice
with the task at hand.
Full source code relating to the issue is available online at:
http://www.oracle.com/technology/software/products/berkeley-db/
index.html
To resume the problem, I need to build a Universal Binary (aka, PPC +
i386) library of BerkeleyDB. Now, normally, this is a simple task but
it seems Autoconfig is working against me.
At the strict minimum, I need to have the following flags set in the
generated makefile:
CFLAGS= -c $(CPPFLAGS) -O3 -isysroot /Developer/SDKs/
MacOSX10.4u.sdk -arch i386 -arch ppc
LDFLAGS= -Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk
The problem is, whatever I set for LDFLAGS or CFLAGS in the .ac file
passed to autoconf, the output Makefile is invariably stripped down
to an empty LDFLAGS declaration and a CFLAGS devoid of the -isysroot
and -arch parameters.
Now being new to autoconf, I suspected I was doing something really
stupid until I stumbled onto this:
http://www.nabble.com/Configure-Support-for-Mac-Universal-Builds-
t3635358.html
So, it seems I'm not the only one having this problem. Sure enough,
manually patching the resulting makefile actually produced the
universal library I was expecting:
> file .libs/libdb-4.5.a
.libs/libdb-4.5.a: Mach-O fat file with 2 architectures
.libs/libdb-4.5.a (for architecture i386): current ar archive
random library
.libs/libdb-4.5.a (for architecture ppc): current ar archive
So, a current workaround would be to tweak my build sequence to hack
the proper settings using sed & awk but this somewhat defeats the
purpose of running autoconf in the first place.
The question is, is this a known bug and/or is this on the radar of
things to do for Autoconf?
