Dear Geant4 users,
How to activate multithread when running geant4.11.0.2 examples?
For example when the following command is applied:
/run/numberOfThreads 2
(also with change number 2).
It did not work and the following error appeared:
"
***** Illegal application state </run/numberOfThreads 2> *****
***** Batch is interrupted!! *****
-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : UIMAN0123
issued by : G4UImanager::ApplyCommand
Command aborted (200)
Error code : 200
*** This is just a warning message. ***
-------- WWWW -------- G4Exception-END --------- WWWW -------

I think (but not sure) the error come from the cmake compiling that appear in compiling (my cmake version is cmake-3.5.0-rc3) and the follwing line appeared :
Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failedas
the following is all terminal output :
