[Gate-users] R: Centos 8 compilation issues

Wed Jan 27 20:34:17 CET 2021

Dear Xinjie,
Actually I installed Centos 8 more than 14 months ago, I’m pretty sure it’s stable. Especially considering that Centos 7 ended with 2020 the full support cycle. I can’t downgrade now!
Furthermore, back then I installed it because I understood that it was the approved CERN OS, after SLC was stopped! I hoped it was compatible with all “cern-related” software

Hello Presotto,

I am not sure what happened to your compilation error, but I met some issues when I tried to install GATE on centOS 8 a few months ago. If CentOS 8 is not the most necessary system you need, I highly recommend you switch to CentOS 7 as your operating system so you could avoid many issues. It looks like there are still many bugs in CentOS 8 because it was just released in late 2019 and it is not a very stable system yet. I do not know whether you got another issue with the QT version, but I failed to install GATE successfully on centOS 8 before with almost an entire week's effort.

Best,
Xinjie

Is the problem that my compiler is outdated? It’s the one that comes with the latest Centos kernel, updated days ago. Actually I’ve been told that I should use gcc 6.3 for that Gate version instead of gcc8

Only just had a quick look. It also seems to me like an issue with ROOT as well. The note at the end of the output makes me think that your compiler is too outdated to understand certain C++17 features. You could check that. Were you able to compile ROOT without issues? I am wondering if there are any parameters/flags in the gate compilation regarding the supported C++ version.
Just some thoughts.
Coraggio

Please find attached the compiler output that another user asked me privately.

I've been suggested it might be a ROOT version issue. I'm using ROOT 6.22/06

Oggetto: Centos 8 compilation issues

Dear experts,

I’m trying to install Geant and GATE on my personal PC. I converted my PC to Centos 8 that I understand it’s what CERN is using as they’ll not be making SLC8.

I’ve successfully installed Geant v4.10.05.p01 , and examples B1 and B2 run. I’ve also tried to install Gate 8.2 and as soon as I type make I get a huge number of disparate errors that I’m told to be dependent on my gcc/g++ version, which is 8.3.1

I’ve been told that I should install gcc 6.3, but I can’t find any way to do this on centos 8, while it appears to be simple in centos 7.

What do you recommend me to do? Is there a simple fix to make the compilation run in centos 8? My student managed to compile it on ubuntu with gcc 9! Or is there a way to install gcc 6.3 in centos 8?

Thanks in advance!

Luca
