Thread: libpq.a in a universal binary
I am trying to create the libpq.a as a universal binary (both ppc and intel macs). Does anyone have any information on this process? Thanks, Ted

I use the following notes to build libpq and the bin/ tools to ship with pgAdmin. I know it is possible to build the entire server, as a Universal binary, but I could never make it work and haven't had time to spend on it. Comments welcome :-) ====== Building the entire server as a Universal binary doesn't seem to work at present, so, we build the backend as an architecture specific build, then create libpq and the tools as Universal binaries over the top. # ./configure --with-openssl --prefix=/usr/local/ # make all; make install # make distclean # CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386" LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386" ./configure --with-openssl --prefix=/usr/local # make all Note - this step will fail, but is required to complete the build of the tools. # cd src/interface/libpq # make all; make install # cd ../../bin # make all; make install ====== Regards, Dave
Hi, The short summary that I use for .a files is: Build on PPC Build on Intel On either run lipo -create lib/libpq.a ../ppc/lib/libpq.a ../intel/lib/libpq.a Before a file libpq.a shows libpq.a: current ar archive After lipo it shows: libpq.a: Mach-O fat file with 2 architectures libpq.a (for architecture ppc): current ar archive libpq.a (for architecture i386): current ar archive random library There is a nice Apple tech note on this http://developer.apple.com/technotes/tn2005/tn2137.html that talks about Universal Binaries. It's possible that you might be able to do this all in one go since the Apple compiler can support generating both intel and ppc output in the same fat file. But, if you can't, then the above technique works just fine. cheers bruce Ted Petrosky writes:> I am trying to create the libpq.a as a universal binary (both ppc and > intel macs).

The method I gave, while a little hacky, does work well and is pretty straightforward. It's also probably the only way that would be practical to build and install the whole tarball in a vaguely normal way (assuming there weren't other issues preventing the build completing).

Thanks for the reply.... at last nights cocoahead meeting in NYC I asked and found a solution for libpq.a. 1. config and make on a ppc 2. config and make on intel copy and rename the libpq.a from each system to a common directory and run 'lipo' on them: lipo libpqppc.a libpqintel.a -output libpq.a lipo will create the universal binary man lipo: LIPO (1) LIPO(1) NAME lipo - create or operate on universal files SYNOPSIS lipo [-info] [-detailed_info] [-arch arch_type input_file] ... [ input_file] ... [-arch_blank arch_type] [-create] [-thin arch_type] [-replace arch_type filename] ... [-remove arch_type] ... [-extract arch_type] ... [-extract_family arch_type] ... [-output output_file] [-segalign arch_type value] ... DESCRIPTION The lipo command creates or operates on ``universal'' (multi- architec- ture) files. It only ever produces one output file, and never alters the input file. The operations that lipo performs are: listing the architecture types in a universal file; creating a single universal file from one or more input files; thinning out a single universal file to one specified architecture type; and extracting, replacing, and/or removing architectures types from the input file to create a single new universal output file.

The PostgreSQL build doesn't use the dependency tracking (at least not by default) so that's not an issue. pgAdmin does on the other hand, and the build will fail loudly if you don't disable tracking when you configure. > Another possibility (the better option) would be to add an option to > build universal binaries - such as --host=mac_universal or would that be > --host=darwin_universal - to automate the CFLAGS and LDFLAGS settings. > Adding --with-isysroot= should be added to support non-standard and > future SDK setups as well. In pgAdmin we figure out what to build for based on the wxWidgets installation. In PostgreSQL's case, I would imagine we'd need to list the architectures to include in the build per the example above however it was automated (you might want ppc and ppc64 but not intel for example). FWIW, from memory the PostgreSQL build fails at the point at which it links all the SUBSYS.o's. Regards, Dave

You could have a few options - --host=darwin-ppc-i386 --host=darwin-ppc-ppc64-i386-amd64 etc. maybe this could be better setup by splitting the string after darwin_ instead of having many different single hosts as such. If host starts with "darwin" and len(host)>6 arch_string() = explode("-",ltrim(host,7)) CFLAGS=CFLAGS+" -arch "+arch_string(x) else build for current cpu Maybe the --host= options with all the different possibilities won't be taken in, but I think a TODO should at least be added (not a high priority) to support building universal binaries even if only fixing the current failure point so that one make command can be used to get the end product even if it is a partly manual configure. And this would apply to the client libs more than the server itself. > FWIW, from memory the PostgreSQL build fails at the point at which it > links all the SUBSYS.o's. > Actually now that I checked it on a clean source tree (8.2.0) and not a make/make clean'd source tree it does appear to get to the SUBSYS.o's (when I make clean then set CFLAGS etc it stopped at the beginning) As I said I hadn't looked into it much and my first impression of trying this gave me misleading thoughts of what was needed. -- Shane Ambler pgSQL@007Marketing.com Get Sheeky @ http://Sheeky.Biz

As it is now :-( I've got your followup email though, so I'll try a build as soon a I can - thanks! Regards, Dave.
take a look at this link.... http://www.entropy.ch/blog/Software/2006/02/04/PostgreSQL-Universal- Binary-Build-Tips.html does this help?
