[SOLVED] guvcview fails to compile on 14.1 32 bit system.

When I run the slackbuild for guvcview, I get the following errors:

Code:

make  all-recursive

I have searched the forum for similar problems. These errors are beyond my understanding. There are some problems with more than one copy of header files. However, I don't know which one I should have, and what might be an old one.

The system was recently upgraded from 14.0 to 14.1. I did a full install. I had a long list of sbopkg's to upgrade. All have worked, except guvcview, and tesseract. The errors in tesseract are similar, however, different .h files are mentioned.

Right now I would like to fix guvcview, and understand what is wrong with it. Then work on tesseract.

Suggestions?

General answer: send an email to the maintainer of the SlackBuild, or to the Slackbuilds-users mailing list.

An update. I have compiled guvcview on my laptop, copied the sbo package on to the failing system and installed the update. I did the same with tesseract. Both programs are now at the levels listed in slackbuilds for 14.1.

The laptop I compiled the programs was a clean install, I had partitioned the disk, and formatted, installed, and the slackbuilds run.

On the failing system, I had upgraded from 14.0; so now I think the problems were caused by some old files left around, that were not updated or replaced with the upgrade process.

Hope this helps anyone with similar problems.

You can use this command to check for missed packages during upgrade
slackpkg install-new

gengisdave · 01-24-2014, 02:02 PM

the error is in file /usr/include/linux/v4l2-controls.h which come from package kernel-headers, if you can't fix it, reinstall or repackage it

Willysr,

I ran 'slackpkg install-new' however nothing showed up as missing.

gengisdave,

I reinstalled the kernel headers

Quote:

kernel-headers-3.10.17_smp-x86-3

and was able to build guvcview without problems.

Thank-you both for your help. This thread is solved.
