@kjvbrt Please have a look at this

Hi @andresailer,

I'm getting crashes at m_runManager.Initialize();, when running tests locally at Alma9/nightly stack.

The tests which are failing are testing magnetic field tools, failures occur either for IDEA-LAr and CLD. One of the failing tests:

SimG4Components/tests/options/magFieldFromMap.py

Hi @kjvbrt
Did you also update k4FWCore with the change in IGeoSvc?

[kjvbrt]

Hi @andresailer,
I compiled branches addAccessor in both repos (k4FWCore first and after that k4SimGeant4)

[andresailer]

Where is "k4simgeant4env.sh" supposed to be?

k4SimGeant4/Detector/DetComponents/CMakeLists.txt

Line 30 in 90f21af

COMMAND bash -c "source k4simgeant4env.sh; k4run ${CMAKE_CURRENT_LIST_DIR}/tests/options/magFieldScanner.py"

Which is also used by that test in FCCDetectors.

[kjvbrt]

k4simgeant4env.sh is in build directory, it's generated.

[andresailer]

Thanks @kjvbrt
I was building everything together and that didn't create this file.
I found the offending IGeoSvc.h in this repository and removed it. Locally that test is passing now.

[kjvbrt]

great, merging.
