Good morning everyone,
I solved the compilation problems …
After a series of unsuccessful tests with the disabling of
Bitdefender I did a series of cross-checks between
the machine that works and the one with the problems.
Both machines have an I7 with 16GB of RAM and SSD.
They have the same version of Win10 with the same updates.
It made no sense.
I have analyzed the applications recently installed on the
two machines and I found that on the machine it was giving problems
I found a copy of RAV Antivirus installed.
I removed it and everything was fine including the problems
of slowness.
Bitdefender had nothing to do with it as it is installed on
both machines.
Thanks everyone for the suggestions.
