New computer - back to building OSCAR

[happydreams]

Old laptop motherboard died.  Ran for 3 weeks on a Raspberry Pi 4.  Finally my new laptop arrived!  Nice new, fast machine.  Lots of cores.  So to build OSCAR again.
Installed the dependencies.  (Still Ubuntu 20.04.1 LTS)  Did a fresh git clone.  Build fails

Code:

cc1plus: all warnings being treated as errors
make[1]: *** [Makefile:2186: intellipap_loader.o] Error 1

Any clues?  I'm not even using the intellipap machine.

Are you building within Qt Creator or using the command line?

Oops! You're hitting a difference in compiler warnings. That error is in the new DeVilbiss support code. I'll fix it ASAP and let you know when there is new source code to test compile.

[GuyScharf]

ok, fix to intellipap loader has been merged. Please try again and let me know if there are any other errors.

Thumbs up!  Built with no problem.  Thanks

On Xubuntu 20.04.1 (Ubuntu with xfce GUI), it also works.

[happydreams]

To build an installation package for Ubuntu, does one mkDistDeb.sh?  I really didn't understand the instructions in BUILD_Linux.md.  From where does one invoke this?  There is a notice to not cruft up things, but no guidance how to avoid it.  I created a folder Packages under Apps/OSCAR.  So from /Apps/OSCAR/Packages I would invoke $ ../OSCAR-code/Building/Linux/mkDistDeb.sh ?

These newer releases of Ubuntu make it very hard to manually create  a working desktop launcher.  Creating launchers was easy even 6 months ago.  All the online instructions don't work anymore as the option in the right click menu is gone.  I have 20.04.1 LTS.

When I build packages, I created a Packages folder, as you did, and then copied all the files in Building/Linux into it. They don't change very often, so I just leave them there. Then in Packages I do "./mkdistDeb.sh Ubun18" - as I build an 18.04 version, then do some tinkering to change a library dependency for 20.04 (I don't really like 20.04, so I've stayed with 18.04 for building.

I usually use Debian Buster/testing as my regular desktop, though.

Where can I find fpm?  

mkDistDeb.sh fails fpm: command not found.  

fpm isn't in the regular Ubuntu 20.04 repository.  I found a repo on github, but not sure if there are various versions.

This newer version of Ubuntu 20.04.1 is getting on my nerves.  Don't care for Gnome 3.36.8

[pholynyk]

From my notebook (I'll add it to the building file):

apt install ruby ruby-dev -- this will add a lot of stuff
gem install --no-document fpm --- this will do a lot of stuff

That should do it; sorry about the omission
