Description hangglider 2021-10-05 16:29:04 UTC
media-libs/codec2-1.0.1 makes gnuradio to abort compilation because of /usr/include/codec2/freedv_api.h:148 contains

typedef void (*freedv_callback_rx_sym)(void *, _Complex float, float);

what makes swig report an input error.

Downgrading to codec2-1.0.0 solves that, as it doesn't contain the declaration.

Please do include the full build.log and emerge —-info.

sorry - didn't recognize this, will have to regenerate asap.

But maybe it's much better to fix gnuradio, if the problem occurs only there. Here ffmpeg is another dependency, didn't notice the prob there, will also retry that.

Comment 5 hangglider 2021-10-20 16:24:46 UTC
* emerge --info and build.log attached,
* ffmpeg, which also depends on codec2, compiles fine.

As it'd be better to fix gnuradio in that case, so please close this bug report.

Yeah, and that version was removed from the portage tree...

Yeah, and that version was removed as "obsolete"
Comment 8 Miroslav Šulc gentoo-dev 2021-11-14 13:10:30 UTC
tbh from the comments i'm not even sure whether codec2 is broken or gnuradio is broken. anyone has a better understanding of the issue?
Comment 9 WGH 2021-11-14 13:18:06 UTC
It could be a swig bug, too

> The problem is swig and its C/C++ parser. Then, the fix depends on which version do you use: release or trunk. The former doesn't have swig/swig#252 and swig/swig#1770 and this is the reason for #233 to work.

The complex thing has been removed from codec2 because of this very issue - - but there has been no new release.

The linked Gentoo PR backports the fix (the complex removal).
Comment 12 Miroslav Šulc gentoo-dev 2021-11-14 13:25:38 UTC
ok, so i reverted the removal of the previous version as it seems it's easier and faster "fix" then to fix the real issue, at least as of now.

to avoid emerge of codec2-1.0.1, you can mask it.
