We were all learners at tsome point! ;-)

We basically have a set of toolchains for various presets, like with or
without threads, with or withour locales, with glibc or uclibc, on
different architectures, and we have some autobuilders that constantly
build random package selections with a randomly choosen toolchain:

    http://autobuild.buildroot.org/
    http://autobuild.buildroot.org/toolchains/

It is interesting to test with at least uClibc and glibc (like you did),
but also with a very "light" toolchain that has no fancy stuff: no
threads, no IPv6, no locales... such as this one:
    http://autobuild.buildroot.org/toolchains/configs/br-arm-basic.config

Use it as thus:

    wget -O defconfig http://autobuild.buildroot.org/toolchains/configs/br-arm-basic.config
    make BR2_DEFCONFIG=$(pwd)/defconfig defconfig
    make menuconfig    (select whatever package you want to test)
    make

It helps find the obvious basic requirements.

Then, for the not-so-obvious requirements, we have the autobuilders to
do all the testing. ;-)

Cheers! Thanks for the submissions! :-)

Well, you can have a look at the Patchwork, there are quite a few
multi-media related patches pending:

    http://patchwork.ozlabs.org/project/buildroot/list/

[--SNIP--]

I did not find anything highly suspicious in that patch. Good. :-)

However, we now like to store hashes for the tarballs we download, so we
can test for integrity :

    http://buildroot.net/downloads/manual/manual.html#adding-packages-hash

Sourceforget provides SHA1 hashes when you click on the (i) button next
to the file you want to download.

Care to respin with that file added, please?

Regards,
Yann E. MORIN.
