Hi William.

I was trying to install this tvheadend on my box.

I got this compilation error:

-----
Tvheadend Data Directory:
  /usr/share/tvheadend

CC              build.linux/src/main.o
/tmp/SBo/tvheadend-3.4patch1/src/main.c: In function ‘tvhlogv’:

cc1: all warnings being treated as errors

Seems to be a warning treated as error. I was including:  -Wno-error
directive to avoid this in SLKCFLAGS in tvheadend.SlackBuild and other
possible places with no sucess.

I do not have experience in compiling C source code. Please review this and
let me know If I can do something from my side.

Thanks in advance for your help.

Francisco.
