Make all errors when trying to install Artemis.

[MartinRogalla]

I tried to install Artemis on Ubuntu 15.10. Following the INSTALL instructions, I executed the make fetch-apt command successfully. I was unable to execute make fetch-qt, since the referenced gitorious repository is not longer existent. Instead I installed qt via sudo apt-get install qt-sdk.

I then configured the environment variables and ran make all. It runs correctly for a while, but then reports the following problems:

Do you have any ideas on how I can fix this?

Hi Martin,

Sorry you are having issues. I won't be able to try to reproduce this until I'm back at work in the new year, but I suspect it might be related to a new version of GCC in 15.10.

Qt Version

It looks like your qt-sdk package includes everything we need. If you have done make fetch-apt you should have everything. Double check you have Qt 4.8.x as the default version with qmake --version (second line shows Qt version). By default in Ubuntu it is 5.x nowadays, it can be changed to 4.8 with the qtchooser tool or by installing qt4-default.

GCC Version

Apparently 15.10 now ships with GCC 5.x. We are a bit sloppy with how we use some c++11 features without building with -std=c++11. I would not be surprised if a major version update to GCC changes which features are enabled by default and breaks the build. (My gcc --version gives me 4.8.4 on 14.04.)

If you can, try building with GCC 4.x (or even 4.8.x) if that's not what you already have.

If that doesn't help, or if you have any other questions please don't hesitate to get in touch.

Hi Ben,

Thank you very much for your quick and detailed response. Since I was running this in a virtual machine anyway, I just downloaded 14.04. Works perfectly on there. I think the Qt version is fine on 15.10, since sudo apt-get install qt-sdk also installs Qt 4.8.6. So it probably is indeed an incompatibility with GCC 5.x. Anyway, I'm glad that it works now.

Thanks again and happy holidays!

Kind Regards,

Martin

Glad to hear you have it working now. Let me know if you run into any more issues - Artemis is a research prototype and not production software so there are some rough edges. For example the "standard" mode of Artemis does not work the same as the description in the paper in the current version, as preparation for some other work we have been doing. So if you are trying to reproduce the paper you will likely run into problems. If this is what you are trying to do I will dig out my notes about what needs to be reverted to get it working again. Feel free to email me directly, but opening issues here is fine too if that's easiest.

I will leave the issue open for now as there is obviously some documentation missing!

Ben
