What version of ubuntu do you use @Peregrin4? I have several versions of ubuntu installed on an intel based PC. I will be happy to help you. You need to follow the “Download” option at the top of this forum and click on the rightmost of the three options near the bottom of the page.
That will lead you to to a descriptive page at “launchpad” which is the preferred way to catalog a “PPA” containing libraries for Ubuntu. You will need to open a terminal window on your ubuntu system and enter the three command lines each starting with the word “sudo” listed on that page.
The result will be that you add the repository, update the symbol table, and install the Seamly2d software.
Please try to follow these instructions and feel free to ask if you need further help
I just read your second question, and yes, the builds are for the amd64 and i386 architecture. I believe that you are able to get source libraries and do the compile and build yourself. Packaging and releasing a version of Seamly for your architecture might be useful to others and once you get it working on your own machine the packaging might be something you would like to donate to the community.
Thanks! I have 16.04.1 (Xenial) but on the packages page there is no mention of Power PC only amd64 and i386, so I don’t know if those PPAs are usable for me…
If you are able to download the open source version of Qt it should be doable. I have cloned a copy of the source to my local machine and built it so that I can make local changes. The source code is on github. GitHub - FashionFreedom/Seamly2D: Open source patternmaking software.
If you are interested in creating a local copy I will help you as much as I can with configuring the Qt creator package so that you can do the local builds from source
Thanks for all of that info. I have a spare pc. I think I should install Ubuntu on it so that I can also know what I’m talking about when trying to help people on here
I have kind of a double task, since I have first to make my PPC install a little more reliable… It crashes often, but I don’t know if it’s due to a faulty monitor… Hopefully I get there…
I hope it is a 64 bit. Download Ubuntu Desktop | Download | Ubuntu If it is a 32 bit, you will need to install the 16.04.04 version (an older version and the last long term supported 32 bit I think) Xenial is the named designation for the 16.xx versions of Ubuntu. I do most of my work on “Bionic” which is the 18.04 version.
I was looking at cross compilers available as part of the ubuntu stack. It is probably possible to build a version for the powerpc processor in the pipeline (travis.ci) Whether the code would run efficiently on a particular platform is a different issue.
