Slow startup

[OtaviusDecius]

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?
