Problem with PKGBUILD of ql700lpr

Hi there!

I am currently trying to setup my Brother QL-700 using yaourt. However, if I run 

yaourt -S brother-ql700-cupswrapper

to install the printer driver, it also tries to install brother-ql700-lpr. As I tried to use the delivered PKGBUILD file I ran into several errors, which where caused by wrong paths and an outdated MD5 checksum. So I updated the checksum and fixed the paths by changing from usr/local/Brother to /opt/brother. Which I think should work well, but I am not sure what the last three lines of the script

sed -i 's|/usr/local/Brother|/usr/share/brother|g' `grep -lr '/usr/loca$
find . | cpio -p -dum $pkgdir || return 1
install -D -m644 license.txt $pkgdir/usr/share/licenses/$pkgname/licens$

do and so I am not able to fix them. Could somebody help me with this? And how could I push the new PKGBUILD back to the repositories, so others do not have the same problems?

Thanks and best regards

Andreas

Re: Problem with PKGBUILD of ql700lpr

Hi, and welcome to Arch Linux.

You've a few options.  For details, make sure you read the AUR wiki article, in particular this part

tl;dr:  Start by flagging the package out of date and posting your fix to the comments.  That way others can see it.  If the maintainer does not respond, send them an email.  If they still do not respond, ask the mailing list to have the package be orphaned.  Provide documentation of your attempts to contact the maintainer.  When the package is orphaned, adopt it.  Upload your changes. Profit smile

Hi ewaller.

Thanks for your quick reply. I have flagged the package as out-of-date and added a link to this post in the comments. I will update this post, if I get a reply. :-D

Re: Problem with PKGBUILD of ql700lpr

I've updated the package(s) to reflect more closely what Brother does in their Debs and RPMs.

Unfortunately, like I mentioned in the package comments, when trying out a Test Page I get a segfault. Which was never a problem before... (I was printing hundreds of labels tongue)

I'll keep investigating. But let me know if you find something.

Re: Problem with PKGBUILD of ql700lpr

All fixed now big_smile
Above segfault was due to the binary strings now being different length because of Brother's bizarre directory structure change (which I don't think works on the supported OSs...).

I've mentioned in the package comments, but the package now automatically adds the printer (via Brother's scripts) to cups. If the red light is flashing, make sure the paper size is set correctly.
