Audacity can't find ffmpeg

[rpspringuel (Fr. Samuel Springuel)]

I've installed the latest audacity and ffmpeg ports (along with their dependencies) and Audacity is complaining that it can't find the ffmpeg libraries (and thus can't open m4a files). When I try to manually point to the library (/opt/local/lib/libavformat.57.56.100.dylib) the dialog just goes back to the preferences pane and the same library not found error shows up.

[RJVB (René Bertin)]

What OS version are you seeing this on?

I updated my port:ffmpeg to the current 3.2.2 and audacity immediately saw the new ffmpeg libraries. m4a import still works.

FWIW, I have a personal ffmpeg-2 port that's active. When I open the Audacity log (under the Help menu), I see this:

This looks like audacity was built against ffmpeg 2:

which in turn implies that I would have rebuilt my local copy after I finally upgraded to ffmpeg 3 (which I held off on for quite a while). That kind of surprise me, but anyway.

Could you try to reinstall audacity from source, please?

sudo port -ns upgrade --force audacity

and see if that solves your issue?

[rpspringuel (Fr. Samuel Springuel)]

The build fails with the following error:

Error: Failed to build audacity: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_audio_audacity/audacity/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.

I've attached the referenced log above.

That build error has nothing to do with FFMpeg:

:info:build ld: warning: ignoring file ../lib-src/lv2/liblv2.a, file was built for archive which is not the architecture being linked (x86_64): ../lib-src/lv2/liblv2.a

Annoyingly the liblv2 build hides its details so I cannot infer what goes wrong there, so this may take some time to figure out :-/

Googling the "file was built for archive" error I find this most recent hit: ​https://github.com/MoarVM/MoarVM/issues/334

In that case the error was caused by the use of the wrong ar utility (GNU's instead of Apple's). Confirmed in another hit (​https://github.com/tpoechtrager/osxcross/issues/11).

As far as I can see your build uses AppleClang. Can you check where in your path you have the ar program installed (tcsh has the where ar command for that, bash/sh surely have something similar), and what versions they are?

Replying to mojca:

On the buildbot ​10.11 seems to work (in some way, the build must have succeeded earlier)

Yeah, but (how) do the build bots handle updates to the OS and/or Xcode toolchain?

on ​10.12 it fails with:

ld: warning: ignoring file ../lib-src/lv2/liblv2.a, file was built for archive which is not the architecture being linked (x86_64): ../lib-src/lv2/liblv2.a

...

ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) }}}

That's the same error the OP is getting. We should be able to assume that the build bots don't find the wrong 'ar' command, so something else must be going on which will probably be hard for me to test :-/

[RJVB (René Bertin)]

@ rpspringuel : can you please replace the existing patch-python.diff in `port dir audacity`/files with the attached version, do port clean audacity and repeat the build? For ease of reading the logfile, please add build.jobs=1 to the install-from-source commandline.

The build should still fail, but liblv2 will have been built in verbose mode so hopefully we can get some insight how to fix this.

[RJVB (René Bertin)]

If you're feeling adventurous you *may* try to install the latest audacity-devel port. Not that I'm expecting that they changed anything in how lv2 is being built but who knows. You'll need the Portfile and files directory from ​https://github.com/RJVB/macstrop/tree/master/audio/audacity

and replace the contents of port dir audacity with them.

The version of ar that I have is installed in /opt/local/bin/ar.

I've redone the build with the different patch-python.diff and am attaching the diff.

Replying to rpspringuel:

The version of ar that I have is installed in /opt/local/bin/ar.

Dang, of course, I have that one too.

After updating my cctools to the latest version I get the same error on 10.9 . That's some kind of progress ...

@ rpspringuel : In the meantime, to come back to the initial issue: with a bit of luck you'll be able to complete the build after deactivating cctools. A complete rebuild, of course. Audacity doesn't have any dependencies on cctools that I know of. So you should be able to do

> sudo port deactivate -f cctools
> sudo port -ns upgrade --force audacity
> sudo port activate cctools

truly, really, completely verbose lv2 build ...

patch that restores building with cctools v895 (on OS X 10.9)

[RJVB (René Bertin)]

See also ticket #53449

[rpspringuel (Fr. Samuel Springuel)]

Do you want me to try building with both of those patch-python.diff files and if so with or without cctools active?

[RJVB (René Bertin)]

I'd appreciate it if you could build with the latest version (and cctools active).
(I'd also understand if you want to move on and just get the stuff built, i.e. with cctools deactivated.)

[rpspringuel (Fr. Samuel Springuel)]

I'm happy to try things out in order to get the bug solved, I'm just in the middle of some other dev stuff at the same time so I have to plan out what gets built when in order to avoid overtaxing my system (I'm running a fairly old machine).

[RJVB (René Bertin)]

OK, in that case please try the latest version of the attached patch. Fortunately audacity isn't the most expensive port to build from source.

[rpspringuel (Fr. Samuel Springuel)]

Building with patch-python.3.diff completed with no errors, Audacity is finding the ffmpeg libraries, and it can open m4a files now.

I haven't taken the time to try the patch yet, but it seems like this fix would be a high priority to implement, no? For some reason, the commands in comment:12 did not work for me. Deactivating cctools and then issuing "port clean" and "port install" commands for audacity resulted in the same archive-related error, as if cctools was still in effect. What *did* work for me was to re-activate cctools, at which point it gave me the option to restore an older build of cctools that I still had on my system (several, in fact, but I went with cctools @886_6+llvm38 based on having read ticket #53449). I was then able to clean and build audacity successfully.

[rpspringuel (Fr. Samuel Springuel)]

This problem just cropped back up when I updated all my ports, which included an update of Audacity to 2.1.3. I don't have time right this minute to see if the fix from before (replacing python-patch.diff) works in this case, but I'll try that later in the week and report back (unless there's something else you want me to try this time).

[RJVB (René Bertin)]

Keep me posted. I rely on others to commit changes to my ports so can only hope they're committed completely.

[rpspringuel (Fr. Samuel Springuel)]

Well, this fell off my radar for a bit, but I finally got around to trying to rebuild the 2.1.3 version this morning using the python-patch.3.diff file from above. The build failed and I'm attaching the log.

[RJVB (René Bertin)]

Please see #55115 for this failure.

Just updated to 2.2 and this error goes away. Thanks.
