[SOLVED] sqg -p empty REQUIRES line, why?

mfoley · 03-30-2017, 03:44 PM

I've been happily using sbopkg since posting thread http://www.linuxquestions.org/questi...ol-4175596457/. However, the last several packages I've tried give me the error:

Code:

$ sqg -p passwdqc
passwdqc: empty REQUIRES line. No queuefile generated.
Uncomment SKIP_EMPTY to change this.
Done.

If I use sbopkg interactive mode: Search > pkgname > Add to Queue, it adds it to the queue without problem; no "empty REQUIRES line" warning. I can then

$ sbopkg -i pkgname

and it installs just fine.

Although I can rather painlessly use the sbopkg interactive mode, I don't get why that works but sqg aborts with the "empty REQUIRES line" error. Using the sqg command line is simple. Is there a way I can force sqg to generate the queuefile anyway, like sbopkg interactive does?

Hi,

I believe this is because the sqg would need to create a queue file that would only contain the name of the package itself. And this seems a bit useless, because there is no need to queue only one package when it can be built directly or as part of a bigger queue.

sqg -p <package> builds a queue of dependencies needed to build the package, if any. But passwdqc has no dependency, hence sqg -p does nothing. That's what it says and this is not an error.

But as suggested by the message if you uncomment the line #50 of /usr/sbin/sqg, jut removing the leading # so it becomes:

Code:

SKIP_EMPTY=${SKIP_EMPTY:-NO}

then a queue file will be generated:

Code:

root[/]# sqg -p passwdqc
Processing passwdqc.
Done.
root[/]# cat /var/lib/sbopkg/queues/passwdqc.sqf 
passwdqc
root[/]#

As you see the queue file just contains passwdqc itself, as it has no dependency.

Well, in fact it doesn't actually say "passwdqc has no dependencies". All it says is "empty REQUIRES line", which could mean various things. I took it to mean that the REQUIRES line is required and processing was therefore aborted.

Ah ha! So then, if I try sqg on a package, and it gives me this "empty REQUIRES line" message, that means there are no other dependencies; which means I could just go ahead and run `sbopkg -i` immediately without bothering to create a queuefile, right?

Also, I didn't get that the message "Uncomment SKIP_EMPTY to change this" meant to change that line (50) in the sqg script! I thought it was referring to the package .info file so some such thing whose name/location I had no idea of.

Both messages are uncommonly terse and, to me, unhelpful. Why doesn't it simply say "No dependencies in this package", instead of the cryptic "empty REQUIRES line". The message "Uncomment SKIP_EMPTY to change this", wasn't enough information for me. A simple addition of "in the sqg script", would have clarified that.

For such a single-purpose tool with few options, I've spent a lot of time and not a few threads trying to figure out its laconic help and feedback!

Right.

This suggestion should be addressed to the current maintainer aka Willy. See how to contact him in the script itself.

Alternatively, you can open an issue or make a pull request on GitHub: https://github.com/sbopkg/sbopkg

Oftentimes, it helps to have a look to the program that displays a puzzling message, in this case the easy to read shell script /usr/sbin/sqg.

Also http://docs.slackware.com/howtos:sla...es_with_sbopkg is worth reading.

Thanks for the feedback. The code was added long time ago (2013). I will have a look on this matter asap.

Well apparently Willy reads this forum, or someone else contacted him! Willy, if you're still reading, thanks for your attention. sqg is a great program and I appreciate your efforts.

Didier: thanks for the clarifications. I can continue happily on! I will definitely check that link.

It's fixed in master already
hopefully the new message makes more sense

mfoley · 03-31-2017, 12:08 PM

Kool! Thanks!!!!
