Hello Probonopd

the first thanks for testing QtMips in APPimage format. I do not have experience with APPimage. Basic build is thanks to Frantisek Vacek contribution. I would expect that inclusion of libxkbcommon-x11.so.0 in the image is not the right solution because it should match the one distributed with X11. But may it be it is right to put more libraries into package .... I am not sure.

As for Ubuntu Xenial, we have packages specially built for that version and they should be OK. But I personally use no Ubuntu, so packages are build without real testing. But next comamnds sequence is tested by many students of our course https://cw.fel.cvut.cz/wiki/courses/b35apo/en/start

sudo add-apt-repository ppa:ppisa/qtmips
sudo apt-get update
sudo apt-get install qtmips

But I would like to have as good APPimage as possible. Suggestions or pointers to examples (i.e. other basic Qt5 using applications) are welcome.

Best wishes,

Pavel Pisa

Hello @ppisa thanks for your response. How was https://github.com/cvut/QtMips/releases/download/v0.7.3/qtmips-0.7.3-x86_64.AppImage produced? Can you please add libxkbcommon-x11.so.0 to it, then I can re-run the test and let you know the results.

Thank you very much.

The AppImage has been prepared by my colleague on his own computer. I do not know exact setup.

I have prepared 0.7.5 release of QtMips and managed Suse Open Build Service to prepare AppImage this time. It pushes back to ancient Qt5.6 version and other troubles but I expect that portability should be much better now.

Please, if you can, test the result and give us feedback.

probonopd commented 4 years ago

@ppisa do you have a download link for me please? Thanks a lot.

ppisa commented 4 years ago

The build is from Suse Open Build Service, available there

https://download.opensuse.org/repositories/home:/ppisa/AppImage/QtMips-latest-x86_64.AppImage

It is copied into QtMips 0.7.5 release on GitHub as well.

@probonopd please, did the provided link solve the problem? This build is against libraries chosen by SUSE fr AppImages which should be portable to the most GNU/Linux environments.

Tanks for testing,

Pavel

probonopd commented 3 years ago

Running a test. Let's see how it goes.

ppisa commented 3 years ago

Please @probonopd , can you report actual state of your appimage builds/use for QtMips repo master and devel branches. If it works then please close this issue.

ppisa commented 2 years ago

No response for almost year

probonopd commented 2 years ago

Thanks @ppisa, the test went well, as indicated by the green arrow on 13 Feb 2021.

QtMips is in the catalog ever since: https://appimage.github.io/QtMips/

Thank you very much! :+1:

Thanks for the report.

It seems that the last build is relatively old Tue, 21 Dec 2021 05:55:22 based on 0.7.x version.

We have switched to CMake for future 0.8.x versions and there seems to be problem with automatic AppImage builds on Suse Open Build Service

https://build.opensuse.org/package/live_build_log/home:ppisa/qtmips/AppImage/x86_64

So this is probably for new issue and problem is that we probably cannot build with older Qt5 which is used in OBS. Know to work old Qt5 version - Qt5 5.9.5 which we use for Ubuntu 18.4.1 QtMips build. See

https://code.launchpad.net/~ppisa/+recipe/qtmips-build

Build with Qt5 5.6.2 used for discussed OBS AppImage build is not feasible anymore... I am not sure what are other options for AppImage build.

https://build.opensuse.org/package/show/home:ppisa/qtmips

Generally our main activity is ongoing on RISC-V simulator version now.

https://github.com/cvut/qtrvsim

But it requires alt least Qt5 5.9.x as bare minimum as well.

https://build.opensuse.org/package/show/home:jdupak/qtrvsim

https://code.launchpad.net/~qtrvsimteam/+recipe/qtrvsim-build

We have FlatPack build for it available. AppImage would be interesting but time is limited...

If you have some idea, document it as issue in QtRvSim GitHub project.

For Ubuntu there are Qt builds of 5.15.x even for very old distribution releases. Probably openSUSE/OBS could do the same, but I don't know whether it has been done. Maybe @adrianschroeter can help?
