Switching to a second HDD running Debian 11 in the same machine, same hardware, root.exe is pretty fast at startup.

I have Fedora 35 OS installed on my other desktop (DELL) and root works perfectly, pretty fast:

Given that top output, to get a stacktrace that tells us what ROOT is up to, could you please try to do gdb -p PID (where PID is the PID of root.exe as reported by top) and then backtrace at the gdb prompt? You can then also give a continue, then CTRL-C, and a backtrace again, a few times, to gather a few samples of where root.exe is stuck at.

Alright, getting closer! So, from the manual sampling you did, would you say that most of those 4-6 minutes are wasted in AddHostArguments (then the last 4 frames in the stack are calls to libc)?

OtaviusDecius · June 30, 2022, 7:35pm

Yes, I would.

OtaviusDecius · July 1, 2022, 3:56am

Good news!

I just recompiled root package (from github) upon commenting out these two lines in my .bashrc:

#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64
#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib64

Compilation runs amazingly fast and root.exe starts up very fast now.

Thank you all for the attention.
Luiz Regis

Wile_E_Coyote · July 1, 2022, 8:28am

That sounds weird.
Is there any explanation for it?

OtaviusDecius · July 1, 2022, 3:04pm

Hi Wile,

I am very sorry to say it worked fast upon compilation but after testing it again today the problem persists:

time root.exe -b -n -q; time root.exe -b -n -q;

So, it no longer sounds weird.

It seems we need to find the one responsible for “AddHostArguments”.

@OtaviusDecius Can you make sure that you do NOT have another ROOT version installed in your “${PATH}” (and no ROOT libraries in any “standard” system directories).

Hi Enrico,

here is the PATH:

I wonder, what is this MODULES_RUN_QUARANTINE = LD_LIBRARY_PATH ?

Thanks.

Apologies for not reacting earlier.

What’s slow is thus getting the include paths from your compiler. You can see the actual invocation for that by starting ROOT using EXTRA_CLING_ARGS=-v root.exe; it should display

Looking for C++ headers with:

and that’s what we care about. Could you post the complete output?
