[Buildroot] Bug/Typo in ffmpeg.mk

[universeII at gmx.de]

Hi buildroot guys,
I just found the buildroot project due to a magazine article and I'm really impressed how simple cross compiling is using this tool.

I'm trying to create a system for a 7400 power-pc and I think I found a typo in
/package/multimedia/ffmpeg/ffmpeg.mk

line 148 is:
FFMPEG_CONF_OPT -= --enable-altivec

but should be:
FFMPEG_CONF_OPT += --enable-altivec

My first step is to try running the new kernel/system in qemu, but I'm not sure which option to parameter -M is the correct one for the 7400 CPU.

qemu help gives me the following options:

> qemu-system-ppc -M ?
Supported machines are:
virtex-ml507 Xilinx Virtex ML507 reference design
mpc8544ds  mpc8544ds
bamboo     bamboo (alias of bamboo-0.13)
bamboo-0.13 bamboo
bamboo-0.12 bamboo
ref405ep   ref405ep
taihu      taihu
mac99      Mac99 based PowerMAC
g3beige    Heathrow based PowerMAC (default)
prep       PowerPC PREP platform

Can anyone give me a hint?

Regards,
Andreas

Thanks. Out of interest, what magazine was that?

Good catch! I've fixed it in git now.

I'm not sure for 7400 either (perhaps check on the qemu list), but we do
have a ppc qemu defconfig (make qemu_ppc_g3beige_defconfig). See
board/qemu/powerpc-g3beige/readme.txt for details of qemu options.

make menuconfig is the configuration options for buildroot. To see the
configuration options for the Linux kernel, first make sure you have
enabled Kernel->Linux Kernel and then run:

make linux-menuconfig

To see the menuconfig interface of the kernel.
