[ryandesign (Ryan Carsten Schmidt)]

We had successful builds of this port on all buildbot machines. Could you attach your main.log file, please?

[adamscott (Adam Scott)]

Is there a way to know why it fails? Is this something that I set locally?

[adamscott (Adam Scott)]

I created a fresh macOS Sequoia virtual machine where I just installed the latest XCode and MacPorts. I got the same error, you'll be able to see this in the main_from-clean-install.log file I attached.

[kencu (Ken)]

thd proximate cause for the link not finding the x86_64 symbols is that the library is not fat:

:info:build ld: warning: ignoring file '/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_audio_portaudio/portaudio/work/portaudio-88ab584e7bf4358599744cd662cfbc978f41efbf/bindings/cpp/lib/.libs/libportaudiocpp.0.dylib-master.o': found architecture 'arm64', required architecture 'x86_64'

the reason the library is not fat is the next thing to sort out.

[kencu (Ken)]

my guess is that this somewhat weird-looking link step doesn't have any arch flags in it, so defaults to the primary arch only:

:info:build libtool: link: /usr/bin/clang++ -r -keep_private_externs -nostdlib -o .libs/libportaudiocpp.0.dylib-master.o  .libs/BlockingStream.o .libs/CallbackInterface.o .libs/CallbackStream.o .libs/CFunCallbackStream.o .libs/CppFunCallbackStream.o .libs/Device.o .libs/DirectionSpecificStreamParameters.o .libs/Exception.o .libs/HostApi.o .libs/InterfaceCallbackStream.o .libs/MemFunCallbackStream.o .libs/Stream.o .libs/StreamParameters.o .libs/System.o .libs/SystemDeviceIterator.o .libs/SystemHostApiIterator.o

[kencu (Ken)]

you'd have to examine those objects in the build folder to see if they really are fat objects -- and if they are, try running that step manually with the added arch flags perhaps.

Of course, if it can't be sorted out, the fallback is the muniversal portgroup.

[ryandesign (Ryan Carsten Schmidt)]

I can't reproduce this on macOS 12. Either with the +universal variant or without, all clang invocations use -arch flags. The weird link line in this log that uses -nostdlib does not occur in my build.

This probably only affects Xcode 15 and later due to ​https://savannah.gnu.org/support/?110937

We probably need to patch or autoreconf, although the project also includes an aclocal.m4 that might contain the bad code that needs to be patched.

I filed ​https://github.com/PortAudio/portaudio/issues/994 to request the portaudio developers update their autotools.

Only .libs/libportaudiocpp.0.dylib-master.o seems to be arm64 only.

I did try clang++ -v to the command that fails and here's the ld that is returning the warning:

I found where it fails, when creating .libs/libportaudiocpp.0.dylib and .libs/libportaudiocpp.0.dylib-master.o. It's even said verbatim in the log.

Oops. The culprit was one line above. See that there's no -arch in the command:

:info:build libtool: link: /usr/bin/clang++ -r -keep_private_externs -nostdlib -o .libs/libportaudiocpp.0.dylib-master.o  .libs/BlockingStream.o .libs/CallbackInterface.o .libs/CallbackStream.o .libs/CFunCallbackStream.o .libs/CppFunCallbackStream.o .libs/Device.o .libs/DirectionSpecificStreamParameters.o .libs/Exception.o .libs/HostApi.o .libs/InterfaceCallbackStream.o .libs/MemFunCallbackStream.o .libs/Stream.o .libs/StreamParameters.o .libs/System.o .libs/SystemDeviceIterator.o .libs/SystemHostApiIterator.o

Well, you’re refinding exactly what I posted above…

Ryan has sorted out above that the root cause of the issue is outdated autotools.

That should be pretty simple to fix, while we wait for upstream to update theirs.

Sorry, yeah.

I tried to update the autotools files on my side (on the PortAudio repo cloned on my Mac), but it didn't seem to change the culprit build commands.

I instead tried to create a local Portfile that use CMake instead. It looks like that CMake is now the current buildtool used for PortAudio. And it compiled successfully.

Here's the diff of my functioning Portfile.

Switching from autotools to another build system is typically fraught with peril so I like to put it off until there is no alternative (i.e. until upstream removes the autotools build system). For example, library names and versions often vary between build systems, which has an impact on all other ports using the libraries. If there is any difference in the files installed by the port before and the files installed by the port after your changes, the revision must be increased, and if the library name or version changes, all ports using the library need their revisions increased and need to be checked to ensure they still build.

Your proposal removes all the flags that told autotools what features to enable or disable. Instead of removing them, you likely need to convert them to the cmake equivalents, otherwise the port may perform undesirable autodetection of features. You've also forgotten to make corresponding changes to the jack variant.

My Portfile-cmake.diff wasn't a proposal, I'm sorry (not used to the workflow here). I just wanted to share what I did to make it work, knowing that it isn't optimal.
