I forgot.  In order to build a Universal, you need to include --disable-dependency-tracking.  So like this:

./configure --disable-dependency-tracking --enable-universal

My guess is that a universal Pd running in 64-bit mode will fail to load a 32-bit external.

Portaudio makes now, 64bit pd.  I can also make the 32bit version using CFLAGS and LDFLAGS, but the --enable-universal doesn't work because of the following error:

gcc-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags
make[2]: *** [libportaudio_la-pa_allocation.lo] Error 1

I was thinking, what happens when you have a universal binary pd and you mix external types, like some are 32bit and some are 64bit?  Maybe a universal binary pd isn't so good..

I'll try testing out the 64bit pd-gui-rewrite for a while, see if anything strange happens.

Ok, I updated the portaudio to the latest, updated 3 weeks ago in portaudio SVN.  Plus I fixed your CFLAGS bug.  You should also be able to build universal by doing "./configure --enable-universal" instead of manually setting the CFLAGS/LDFLAGS.

I compiled the pd-gui-rewrite branch today as 64bit with portaudio support, but haven't tested it much.

To compile portaudio as 64bit, you need the the sources from their svn.  If I try to compile using the sources included with pd, I get a bunch of deprecation warnings followed by a syntax error.  If I update the source codes to those in portaudio's svn trunk, the syntax error goes away but there are still many deprecation warnings.  But, I have audio, with and without jack.

The configure script doesn't like it when I do:
export CFLAGS="-arch i386 -arch x86_64"
export LDFLAGS="-arch i386 -arch x86_64"

This is how I compiled portaudio, but when I do it with pd, the configure script reports gcc as unusable.  Is there a better way to make gcc compile universal binaries?

portaudio provides CoreAudio support already.  It is AudioUnit support that is in the works, which I suppose is part of CoreAudio.  What are the errors with portaudio in pd-gui-rewrite?  It would be good to get those fixed there, since you said that portaudio on its own can build fine for 64-bit (or am I mistaken?)

Got it compiled and it looks nice.  The portaudio failed, same as Pd-Vanilla, but I guess you aren't worried about that because you are working on getting coreaudio support (which would be nice).  Jack works, everything is sounds nice and stable. 

The only thing I noticed is that expr cannot be found.  I have only tried a few of the example patches so far.

The build system in vanilla/extended is pretty ugly, especially for Mac OS X.  The build system in the pd-gui-rewrite/0.43 branch has been rewritten from scratch to be a full autotools build system.  That should fix the -isysroot and --disable-portaudio problem you mention.  Try it out, and we can fix any issues there.

cd 0.43
./autogen.sh && ./configure --enable-jack --disable-portaudio && make

Oops, I accidentally just sent my last post to Hans.  Please read this and the post below...

I have been slowly figuring out the last problem, where gcc can't find my headers in /usr/include.  It is because the configure line:

if test "x$fat" == "xyes";
    then
        MORECFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk \
            -arch i386 -arch ppc -Wno-error"

First, I don't know why this is necessary, but I'm sure somebody does.  I also don't know why OS X 10.6 is being detected as fat anything. 

I can install the MacOSX10.4u.sdk from the Xcode disk, but then gcc can't find a good stdarg.h, as the one include within that sdk has a #include_next stdarg.h directive.  Then, with this -sysroot flag, gcc doesn't search any other directory and none of the 20 other stdarg.h files on my computer are found.  I remove this flag and the header files are found elsewhere just fine.

I compiled Portaudio from svn as universal binary with 64bit.  But, this library doesn't work with Pd's portaudio source files and the new sources don't work with Pd's sources.  So, I can't get past building the portaudio objects.  I tried just using jack with "./configure --enable-jack --disable-portaudio", but the build script still tries to build portaudio and fails.

This is all with pd vanilla from Miller's website.  I'm also trying to build the Pd extended sources, but I suppose I should start a new thread for the problem I hit there..

Macports made me a universal binary portaudio, thankfully because I could not get it to compile as 64 bit from the source (I posted why on the portaudio mailing list).

I'm having other annoying problems with my build system, probably something very stupid that I am not aware of.  Neither Pd nor Pd-extended can find header files in /usr/include.  This isn't so hard to include as a CFLAGS flag, but then it still can't find stdarg.h, which just makes me think my build system is broken. 

I'm working through the various errors to getting Pd-extended building on Snow Leopard as 64 bit, but I have to say I'm probably not the best candidate as this is the first mac that I've had in years.  Truthfully, I was looking forward to a time when things 'just worked' :)  Not there yet.

It seems that portaudio should build as 64-bit, perhaps its worth trying to upgrade the portaudio files that are included in Pd-extended.  I recently updated the pd-extended/0.42.5 branch to the most recent stable portaudio.

I'm working getting an Apple AudioUnit sound API support into pd-core right now.  This will support the iPhone, but should also work on Mac OS X.  With this, it should be possible to get working audio on Mac OS X without portaudio.

AFAIK, Fink does support 64-bit now, so as long as the libs support it, then Fink should work.  I'd say it would be worthwhile building Pd-extended 64-bit without the Fink/Macports dependencies, since most included externals don't need any other libs.

You need to set the LDFLAGS to -arch i386 also.  Or even better, try doing a 64-bit Snow Leopard build of Pd-extended.


I'd love to try that, but I'm still working to get a 64-bit Snow Leopard build of Pd-vanilla.  Portaudio won't let me do it yet.  Macports is limited as far as I can see, so I'm having to compile each piece from source.

I've been trying to get my externals to compile in to use with Pd-extended... in OS X Snow Leopard. So far it hasn't been easy because Pd-extended is i386 and my externals are compiling as x86_64.

All I can find on this is to force the build to i386 with the gcc flag '-arch i386', but the linker won't allow it:

ld: warning: in incr.o, file is not of required architecture

and then, I again have the 64 bit version:
$ file incr.pd_darwin
incr.pd_darwin: Mach-O 64-bit bundle x86_64

Anyone know how to get these guys to work with Pd-extended?
