AUR package build error in ffmpeg

[moriartynz]

The issue

When it compiles the ffmpeg library, it throws a fatal error in relation to the assembler code in lpc_init.c, which code uses pd_1. in the movsd commands. The error is: undefined reference to 'pd_1'.

This issue happens with both the git and non-git AUR packages.

My research

I'm no coding expert. Googling these errors, it appears it may be related to the fact that a static .a file is being produced, as opposed to a shared library.

Compilation log

There are so many warnings that my scrollback window doesn't get anywhere near the start of the compilation. Here is the relevant end-bit, though:

Thanks for the report.

Indeed, AUR build is currently failing. This is not the only problem actually. Even if you managed to build it, you won't be able to install the package due to missing dependencies.

Arch is a rolling distro and changing all the time. These kind of problems are somewhat "expected". I will try to fix this soon.

Issue is now resolved in dsnote-git package.

Sorry that it took so long.
