Problem while running code

Federico11 · May 17, 2020, 10:02pm

Hello,
I’ve been using Root only for a few months, I have ROOT Version:_ 6.18/04 installed on the Windows 10 subsystem of Ubuntu 18.04.

While trying to run a .c++ file provided by my professor, I get the following error

Processing letturaFile.C++("lens.txt",40,200,300)...

I’m assuming the error isn’t caused by the file itself, but I can’t figure out the problem. I tried to look at old topics, but I haven’t found a solution yet.
Any help is very much welcome, thanks in advance

Wile_E_Coyote · May 18, 2020, 8:27am

Try: sudo apt-get install libtiff5

Federico11 · May 18, 2020, 8:43am

Thanks for the answer,
I tried that, now the error is similar, although shorter:

That’s for the author of “letturaFile.C” and / or “lens.txt” to inspect.

Federico11 · May 18, 2020, 9:07am

The issue here is that other students executing those files didn’t run into similar problems

Wile_E_Coyote · May 18, 2020, 9:10am

ROOT binaries, which you use, do not fully correspond to your operating system.

The ROOT team provides ready-to-use binary distributions for some systems, including various Ubuntu versions, which you just need to download and unpack (see “Using binaries” therein).

Federico11 · May 18, 2020, 9:23am

I have installed Release 6.20/04 for Ubuntu 18 gcc7.5, do you know what should I have installed instead/how to know what to install? Because besides Ubuntu version I dont know what to check.

Wile_E_Coyote · May 18, 2020, 9:30am

Check:
cat /etc/issue*
gcc --version

Federico11 · May 18, 2020, 9:32am

I got:

Ubuntu 18.04.4 LTS \n \l

Ubuntu 18.04.4 LTS`

and

gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
Copyright (C) 2017 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

That I think is the version I installed Root for.

Wile_E_Coyote · May 18, 2020, 9:34am

So it should be fine (the “library mismatch” warning is just due to the fact that, in the meantime, Ubuntu has upgraded its libraries).

Federico11 · May 18, 2020, 9:41am

I have noticed another thing though, when I start Root the message is “Welcome to ROOT 6.18/04” and gROOT->GetVersion() seems to confirm this.
That seems to me very strange, considering the file I used very recently is the one called “root_v6.20.02.Linux-ubuntu18-x86_64-gcc7.5.tar.gz”.

Wile_E_Coyote · May 18, 2020, 9:44am

In you previous post, you said “I have installed Release 6.20/04”.
Now you say “I used very recently … root_v6.20.02…”.
And your running ROOT says “6.18/04”.
Why don’t you clean up that mess on your computer?

Federico11 · May 18, 2020, 10:03am

I feel like I have expressed myself very poorly. I recently had to uninstall Ubuntu, and, after reinstalling, I have installed the binary called “Ubuntu 18 gcc7.5”. I’m sure I used that while installing, since I still have the file downloaded with that name.
I tried just now to uninstall and reinstall.
To uninstall I used:

sudo apt-get purge root-system* root-plugin* libroot*

I then downloaded again the binary called “Ubuntu 18 gcc7.5” and compiled it.

Running the file .c I get,

I feel like you are quite right about it being a mess, but I honestly have no clue how to solve it/clean it.

Try to find the origin of these offending files:
locate libMathCore_rdict.pcm

Try to completely destroy the current distribution:
sudo rm -rf /home/ubuntu/root/

If this is a ready-to-use “binary distribution” … what do you mean by “I … compiled it”?

Federico11 · May 18, 2020, 10:38am

I meant to say I run the pre-compiled installer (English is not my first language, as you might have guessed).

I tried to destroy it and install it again and it did the trick, the version is the right one now.
I still run into the Fit data is empty error followed by the whole *** Break *** segmentation violation.
and I’m not sure if it caused by the file or by something else.

Anyways, you’ve been very very helpful, thank you so much, at least now I’m not running into problems caused by weird old files and similar issues.

Wile_E_Coyote · May 18, 2020, 10:41am

The “segmentation violation” is most probably a consequence of “Fit data is empty”.

Federico11 · May 18, 2020, 10:46am

Okay, I’ll se what I can find, thank you again

Wile_E_Coyote · May 18, 2020, 11:12am

In your first posts, I can see another ROOT distribution which you’d better completely destroy, too:
sudo rm -rf /home/ubuntu/Applications/root

BTW. If you do not manage to fix the “Fit data is empty” problem yourself, you will need to attach both “letturaFile.C” and “lens.txt” files here for inspection.

Federico11 · May 18, 2020, 11:20am

If I want to discuss the code itself do I need another topic or can I ask in this one?

Wile_E_Coyote · May 18, 2020, 11:31am

It doesn’t really matter. Just attach it here.
