Macro fails during on-the-fly compilation

Dear experts,

while trying to include headers from TPCBase, a root macro fails during on-the-fly compilation with the error
“Trying to access a pointer that points to an invalid memory address.”.
The full output can be found here: https://cernbox.cern.ch/index.php/s/BiRu6oTcusU2f0m

I tried headers from different locations and found that at least TPCSimulation and TPCReconstruction also fail.

Is there any way for me to solve this issue?

Thanks for your help!
Best regards,
Thomas

Hello @tklemenz

Can you try to load manually the libraries before compiling the macro, e.g.

gSystem->Load("libTPCSimulation.so");
gSystem->Load("libTPCReconstruction.so");
gSystem->Load("libBase.so"); // though it should be already loaded by previous calls
.x test.C+

Root sometimes fails to extract the needed library name from the rootmap file. Also, the libTPCBase seems to have some problem with boos, if I try to load only it, it produces the same invalid pointer error (on ubuntu 18.04):

Thanks a lot! That solves the problem.
