_ROOT Version: 5.34.36/
Platform: Ubuntu 18.04.2
./configure --enable-builtin-freetype --enable-shared
I get the following error:
cint/cint/lib/stream/iostrm.h:24:10: fatal error: iostream.h: No such file or directory
In iostrm.h, I see the following:
So, my question is: how I set G__NEWSTDHEADER? It is not mentioned in the configure file.
I naively tried “export G__NEWSTDHEADER=1” but that was not enough.
Okay…, so you’re saying that the standard “5.34.36” does not work on Ubuntu 18?
The difference between “iostream.h” and “” (the normal C++ way) seems rather fundamental to me.
So, how do I install one of the patches that you mention? Do I install it on top of the 5.34.36 files that I already have downloaded? What is the exact command to do this? I am not familiar with git. Should I use the curl command you mention?
Also, the problem is, I use root as part of a GAMOS installation, so downloading ROOT 6 might give me problems when it’s not compatible with GAMOS.
Also, I don’t understand. Just setting “G__NEWSTDHEADER” to 1 should be enough, right? (Although I tried it with export and that didn’t work)
Why do you stillneed to use ROOT 5.34? v5.34 is ROOT from 2012; you should consider upgrading. It’s impossible for us to provide support for 7 year old releases (unless it’s critical for an experiment).
Ok. In that case I will contact the people from GAMOS whose packages still uses ROOT 5.34. Maybe it will work with ROOT 6 as well (although I doubt it, to be honest). Thanks and sorry for the inconvenience
No inconvenience at all - and please tell the GAMOS folks that we’re more than happy to help them migrate! (You’re also welcome to put me in CC if that helps - email@example.com )
I have one more question, if you don’t mind. Where should I get the latest stable version of ROOT from? From this webpage: https://root.cern.ch/downloading-root ? Or should I use GitHub or Curl or wget?
Indeed, https://root.cern/downloading-root is the canonical web page for releases! You can also check out a git tag, or even use the master (for which we check that it’s always working on all supported platforms).
