Tvheadend

Damn thought I'd fixed that. Will try and take a look tonight.

One thing I've noticed is if it fails to download the scan data it doesn't disable it in the install. Also if you deleted the files manually it would fail .

No, I deleted no files. When does it download the scan data?

I noticed that the scan data files are downloaded with curl, but curl is not defined as a build dependency in debian/control.

Indeed, stupid mistake, I'd completely forgotten getmuxlist was even a shelll script.

I'll try and improve this whole setup.

I'm still experiencing errors:

Fetching dvb-scan files... ERROR: Failed to fetch dvb-scan files (use --disable-dvbscan to skip)

If I run the script manually:

DS112j> python /opt/src/tvheadend_beta/support/getmuxlist

(I've deleted '/opt/src/tvheadend_beta/data/dvb-scan' before executing)

That's really strange, as

mv /tmp/getmuxlist.17596/dvb-apps-96025655e6e8/util/scan/* /opt/src/tvheadend_beta/data/dvb-scan

runs without a problem.

I'm a bit confused, as the shutil documentation sais:

The destination directory must not already exist.

As a result of this, I removed the line from your script, where you create the "dvb-scan" folder. The first move operation is fine then and of course the second one fails again, because "dvb-scan" gets created. But that way of implementing a move operation does not make any sense?

There is nothing wrong with the move, it's moving one directory (dvb-s, etc...) into another (dvb-scan/). The only thing I can think is that there is some strange variation in your python implementation which means that it will not allow that mode of operation, and instead should be treated more like a rename.

In other words I need to append the directory name (dvb-s etc..) to the destination so dvb-scan/dvb-s, but I'm not sure that will work or not.

P.S.
What OS you building on and what version of python does it report?

Try changing:
shutil.move(d, out)

to:
shutil.move(d, os.path.join(out, os.path.basename(d)))

yes, that fixed it. What's the difference?

I'm using a Synology NAS with the newest firmware. It's some kind of linux. Kernel: 2.6.32.12, Python: Python 2.5.6

For people who own a Synology NAS, want to compile tvheadend on it and get this error:

create a symbolic link from /opt/bin/bash to /bin/bash

ln -s /opt/bin/bash /bin/bash

bash is not installed per default and is available through ipkg, hence it's located in /opt/bin/bash

explanation: the configure and getmuxlist scripts have to be run with bash. The manuals out here for compiling tvheadend on a Synology NAS advise to start configure like that:

bash configure \
--host=armle-unknown-linux \
--target=armle-unknown-linux \
--build=i686-pc-linux \
--disable-avahi \
--release \
--openssl=/opt/lib \
--prefix=/opt/tvheadend

As a result of this, the configure script itself runs without a problem. But getmuxlist not, as it's called within configure without "bash".
Another solution would be to edit the first line of the scripts to:

#!/opt/bin/bash

But I think it's easier to create a symbolic link one time :)
