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:

Hello, Now installation without issues . THANKS !!!!

@LuckLX : After the patch it builds just fine. Many thanks for the response, time and work you spent.

@LuckLX: There is an upstream bug: https://tvheadend.org/issues/5862. I'm sure they would appreciate your patch.

I took the lazy route with the tvheadend-git package and just built with the "-fcommon" flag turned on.

Apparently, GCC 10 activated -fno-common by default which caused some issues building up until 4.2.8-3.

I added a patch in 4.2.8-4 so it should be able to build again. Please let me know if you encounter issues.

Hi, It will not build. The following is returned in makepkg -si

collect2: error: ld returned 1 exit status make: *** [Makefile:638: /home/user/Downloads/aur-packages/tvheadend/src/tvheadend-4.2.8/build.linux/tvheadend] Error 1 ==> ERROR: A failure occurred in build(). Aborting...

Thanks in advance for looking into it. Cheers

Hello, Not possible to install tvheadend with pamac : first defined here collect2: error: ld returned 1 exit status make: *** [Makefile:638: /var/tmp/pamac-build-hp/tvheadend/src/tvheadend-4.2.8/build.linux/tvheadend] Error 1 ==> ERROR: A failure occurred in build(). Aborting... Please fix that . Thanks !

@LukyLX Sorry for that, didn't pay attention to it in the PKGBUILD. For some reason my CFLAGS did not take it into account. I updated yesterday to GCC 9.2.0 but it was the same. Then I successfully compiled it against libavresample with [env CFLAGS="${CFLAGS} -Wno-error=stringop-truncation"] as it should have been done automatically. Cheers.

@Issenniel You're right but that's why I specifically added -Wno-error=stringop-truncation to the CFLAGS. So those issues are actually handled as warnings instead of errors.
