Comment 2 Dan Horák 2018-10-22 12:04:50 UTC

Trying local verbose build to get the full command line, might be a gcc issue too.

Comment 3 Martin Stransky 2018-10-22 12:29:50 UTC

btw. we're going to switch Firefox build to clang for Firefox 64 and later if that helps.

Comment 5 Peter Robinson 2018-10-24 11:26:40 UTC

So our gcc doesn't enable NEON optimisation by default on ARMv7 because the NEON instructions are optional and hence it's not guaranteed to be available, the NEON stuff should be run time detected not compile time so I suspect that is why it's failing.

We already have aom/av1 built in Fedora as a library, is there any reason why we can't use the system library here rather than building it in the mozilla tree?

If we have to use in tree there might be upstream patches that can be applied to fix the build.

I have no idea. Feel free to investigate that and I'll happily add any arm patches to Fedora Firefox for that or other arm issues.

Already in process, just waiting for "fedpkg prep" to complete on conference wifi :)
