@RoKoInfo

Thx for your help. I use the armv7l architecture. If I use the two flags mentioned, the error message also appears, see @pokabjoern. Seems to me like it has to do with architecture.

When trying to compile for armv7h, I needed both flags, -Wno-error=format-truncation and -Wno-error=stringop-truncation. Compiling was successful, however, I do not know right now, if tvheadend works fine with it.

@Neil

Thx for the patch. Even when I use the patch, I get the same error message as described by @pokabjoern.

Meanwhile I'm at a loss.

Here's my git diff:

As you can see I just added the line above to the prepare() function in PKGBUILD.

Hope this helps,

Neil.

@Neil

I've tried it too and fail.

I've tried the following:

...

uselibav=""
if [ -f /usr/include/libavresample/avresample.h ]; then
    echo "libavresample found, enabling use of libav!"
    CFLAGS="$CFLAGS -Wno-error=format-truncation"
else

...

I get the error message, see @pokabjoern.

What am I doing wrong?

thanks in advance

Thanks @pokabjoern - now I can build tvheadend also :-)

I had to add

CFLAGS="$CFLAGS -Wno-error=format-truncation"

libavresample.so is shows as an optional dependency. Is it worth flagging that it needs to be installed when tvheadend is built if you want transcoding support?

Hello, thank you for this package. I wanted to say that the compilation via yay doesn't work. I had to go to ~/.cache/yay/tvheadend and execute makepkg to successfully compile the program.

The error via yay is :

Using makepkg directly, errors become warnings:
