How to use Reflex?

ROOT
1

Hi,

how can I use the Reflex system in ROOT 5.14/00b? I compiled it with Reflex support but it doesn’t seem to find the namespace:

root [0] gSystem->Load("libReflex.so"); root [1] using namespace ROOT::Reflex Error: namespace ROOT::Reflex is not defined (tmpfile):1: *** Interpreter error recovered ***

Am I missing something? I read the corresponding chapter of the users guide but couldn’t find anything helpful there either.

Thanks,
Frank

Hi,

we don’t distribute a dictionary for reflex yet. If you have the root sources you can run make check-reflex. That will build the reflex based dictionary for reflex, which you can load into root with gSystem->Load("libCintex"); Cintex::Enable(); gSystem->Load("libtest_ReflexRflx"); using namespace ROOT::Reflex;
Cheers, Axel.

Hi,

in the meantime I switched to root 5.15.08 and I am now trying to generate the reflex dictionary for root but it fails with this error:

/opt/root/root_v5.15.08-src # make check-reflex

Here is my system configuration:

uname -a

Thanks for any help,
