dav1d +universal: ImportError: dynamic module does not define module export function (PyInit__csv)

[potterpg]

Is this log enough information?

I am attempting to build all libraries as universal, so that they can be used in a universal built solution.

dav1d is part of libheif apparently...

Looks like the errors are coming from meson, so that's probably the broken port here.

[ctreleaven (Craig Treleaven)]

I see that there is a new release of meson. Might be a good first step?

Tried updating port tree, and then meson, but the meson port still has a version of 59...

So I guess I will try at some later time?

Replying to potterpg:

Sorry. SoapZA is the maintainer for meson on MacPorts. I don't know if he has looked at the update to 0.60 or if there is some concern with it. The meson build system still seems to have some rough edges that have caused a couple of problems for dav1d on MacPorts. The meson release notes don't say anything that seems to be specifically related to the build problem you found...but it isn't exactly a mainstream build environment so the update may or may not help us. OTOH, it unlikely to hurt us!
