Salix OS

OK

Thank's

For a Salix specific package, there is an SLKBUILD file in /usr/src/packagename-packageversion and maybe a few more helper files too.

Copy all the files from that directory to a new one: edit the SLKBUILD file to change the version number. For inkscape in specific, you'll also need to remove the "patch" line, since that is for version 0.48.4. Save it and: if everything goes well, you'll find a package in that same directory after some time.

If you have a SlackBuild from slackbuilds.org, like you posted in your first post, see detailed instructions here:

I see you've posted about this again in the Spanish forum. Really, you just have to follow gapan's instructions. If you're not used to using the terminal, there's an introductory section on it in the user guide, which you could work through. It's in English, but I hope it shouldn't be too difficult to follow. The command line is really very useful, and not as complex as it may seem at first.

To edit the SLKBUILD file, you could use leafpad. Only two minor changes are required: the version number needs to match the version of inkscape you want to build, and you need to delete the line with teh "patch" command. Or you could comment it out, by putting a # right at the beginning. This symbol means anything on that line subsequently will be ignored. The advantage is you can get it back if needed later for some reason.

Then save the file and build the package, using fakeroot.

To install your new package, use spkg:
