gst-ffmpeg on ARM Linux: GNU assembler not found, install/update gas-preprocessor

Gottfried Haider
I've been trying to compile the latest GStreamer for the Raspberry Pi
running Raspbian (Debian).

When I try to build gst-ffmpeg, it fails with the message:
GNU assembler not found, install/update gas-preprocessor

I've downloaded gas-preprocessor.pl file [1] and put it in my $PATH,
with the executable flag set. The "test" target in the Makefile also
succeeds with no errors. Still, the initial error message remains when
trying to build gst-ffmpeg.

Any hints?

(I've successfully built different previous versions (e.g. 1.10.1) of
gst-ffmpeg without this dependency on the same setup.)

Thanks
Gottfried

Some more investigation:


In the config.log I see:

gas-preprocessor.pl -arch arm -as-type -- as -v
unknown as type: '--'
(...)
as: unrecognized option '-_ISOC99_SOURCE'

The first error seems to be caused by $as_type being empty string in
the ffmpeg configure script. Why this is I do not know. If I force the
"-as-type" argument to read "-as-type gas" this will make the first
error disappear, but the error concerning the unrecognized option
remains (and also bites during the actual build).


The output of "as -v" is:

GNU assembler version 2.25 (arm-linux-gnueabihf) using BFD version
(GNU Binutils for Raspbian) 2.25

I am attempting to build FFmpeg on an armv6hf system for this very target.


Ideas?

You cannot get support for building GStreamer (and gst-ffmpeg)
on this mailing list.

If you have an issue with FFmpeg's configure script, please read
its console output carefully, it contains hints on how you can get
support (no investigation on your side should be necessary).
