Thank you. -Pietro

Hi Pietro,

There are several problems in this example.
First of all, there are two missing includes in SplitGLView.C macro:

#include "TVirtualX.h"
#include "TROOT.h"

But also macro alice_esd_split.C itself does not work properly - seems to be it was not ported to ROOT6. I attaching modified macros, which are working for me. Just do root run_split.C.
Probably I also update it in repository.

Regards,
Sergey

P.S. Maybe original authors of macro can give more details: @bellenot @matevz

alice_esd_split.C (16.2 KB) run_split.C (3.8 KB) SplitGLView.C (48.5 KB)

If you like, you can see in PR #7203.
I also adjust there alice_esd.C macro.

Hi Sergey @linev, thanks so much for the fast reply, it did work! -Pietro

@PBR, look also at alice_vsd.C and MultiView.C … this is what I usually recommend people to start with.

@linev, yes, please commit your fixes to master.

Cheers,
Matevz

Hi @matevz, thanks for the tip.

Just as a -fyi for @linev:
the new alice_esd.C I fetched from the repository has issues that prevent completion.

I first ran into the following error:

run_alice_esd.C:229:21: error: allocation of incomplete type 'MultiView'
   gMultiView = new MultiView;

which I fixed by changing line 131 (was: class MultiView;) with the include below:

#include "MultiView.C"

but that only leads to the following errors and I can’t proceed to completion:

Hi,

This should be not necessary - MultiView.C macro should be loaded and compiled when running
alice_esd.C. I will try to check that happens with 6.22/02 version

8

Strange, but I cannot reproduce error with 6.22 version.
Which OS/compiler version your are using?

9

I am using one from a conda distribution, pls. see below (but the same happens with a manual install of “ROOT 6.22/07” and “gcc version 8.3.0 (Debian 8.3.0-6)”)

Can you try to copy recent tutorial into separate directory and try again?
I saw strange effect that after using alice_esd_split.C macro I was not able to run alice_esd.C - got many errors. Only after I clean all generated files and libraries it works for me.

Hi Sergey,
I created a “tmp” directory one level down with some logical links to the relevant sources and nothing else.

If I roll back line 131 to class MultiView; I get the same error as before:

It is really strange CLING error. Maybe @Axel can comment on it.
I attach another way how MultiView.C can be add to the macro. Please try it:

alice_esd.C (3.3 KB) MultiView.C (4.7 KB) alice_esd_html_summary.C (9.8 KB) run_alice_esd.C (14.8 KB)

13

May be reason for problem was that in MultiView.C defined struct MultiView, but in run_alice_esd.C macro via forward declaration as class MultiView. I will provide PR where such ambiguity solved and MultiView.C just included as extra source file.

14

OK I get the following error:

Generated files by alice_esd.C and alice_esd_split.C macros are not compatible.
You need to start from clean directory

16

OK. What is the step? or macro? that generates the “aliesd” directory that is appropriate for the alice_esd.C tutorial?

17

When you start alice_esd.C macro, it generates aliesd folder with all extra sources.
It is main reason why I split alice_esd.C and run_alice_esd.C macros

18

Perfect, did a “root alice_esd.C” and it works! Thanks!
