Dear ROOT experts,
I have a CMake project on my mac-os which was able to be compiled and i was able to create custom object in python via the pyROOT bindings until root 6.18.
I recently upgraded ROOT and compiled it from source using v6-22-00-patches.
When i did this , the code i had successfully compile.
My CMake root-based project “deeply” use the generate_dictionary functionalities to bring my classes into python and to customly load libraries in some MACROS we have.
Then i had a package called kernel for example, which i compile into a library which should be able to be imported and being used inside a python session.
Now, what i see happening is that i can compile the code, the dictionaries are produced properly, however if inside a python session I run
[0] import ROOT as r
[1] r.gSystem.LoadLibraries("libkernel")
[2] e = r.EventType()
where EventType is supposed to be a class i build and for which a dictionary was generated.
the error i get is the following
In [3]: r.gSystem.Load("kernel/libkernel")

I can share the reduced code i am using (CMakes and header/source files ) if needed. It’s part of a private code analysis, thus i can send it only via mail.
Thanks in advance,
