A "depends on BR2_arm" should be added here. We generally try to hide
such architecture-specific packages when they really don't make sense.
Of course, technically speaking, it should only appear if the SoC is an
AT91 SoC that has this specific video unit, but we are not able to do
that with the existing Buildroot options. But we still try to make such
options depend on BR2_arm.

Please add a justification here in a short comment before the
_AUTORECONF option to explain why it's needed. Normally, it's not
needed for tarballs when no patches are applied, so we try to give a
short justification through a comment.

Isn't the configure script capable it detecting those libraries? What
fails if you don't add all those -I values?

Link to an upstream URL. Could probably be the same as the other
package.

Spaces before and after =. The _SOURCE value is the default, so you can
get rid of it.

If it's empty, then it's not needed. The default _BUILD_CMDS for a
generic-package is empty anyway.

If you use -D, then you must path a complete path as a second argument.
Otherwise, if the destination directory doesn't exist, then your file
will be copied as the directory name. I.e, you "libblabla.so" would be
a file named "lib" under the usr/ directory.

If we want to do a wildcard-based copy of files, I don't think install
plays really well. We generally do a 'cp' instead in this case, but
maybe others could comment on this specific point.

Best regards,

Thomas

There is no configure script in the archive so you basically have to run
autoreconf to be able to build.

The configure script itself seems to be able to find the includes
correctly but the include path is limited to . and .. when compiling so
I had to force the -I at configure.

It may be related to the way I'm using autoreconf. I think that package
is expectig you to use gst-autogen.sh to do that but I could'nt get that
to work.

Hi,

Will you send a v2 fixing the comments Thomas had?

For the on2-8170-libs package, do you know what toolchain the binaries
have been built with? Do we need to limit the C library / arch variant
to ensure it is only available on compatible configs?

I think it's ARM9 only, so we can probably be slightly more specific:

  depends on (BR2_arm920t || BR2_arm922t || BR2_arm926t)

And the only device I've ever seen with this IP block integrated are
at91sam9m10/11, both of which are arm926t.

I had a look again today, I addressed almost all the comments but I'm
still try to figure what is happening with the configure script.
It is actually find glib and the other one correctly but it is not using
the correct environment variable in the Makefile.

I'll try to send something next week.

The symbol that are coming from the libc are limited and if I recall
correctly, it was working with a toolchain built by buildroot (that is
using uClibc).
