Print functions undefined

[FreyJo]

I have the issue that clarabel_DefaultSolver_print_to_file is not defined in the shared library after compiling Clarabel.cpp.
I am using the clarabel in acados with the changes shown in #70.
I used nm libclarabel_c.so | grep "_save_to_file" to verify that the function is actually missing in the shared lib.
Is there any compilation flag or option that I have to set in order to use this function?
This function would be very useful to investigate problems of the acados clarabel integration.

I stumbled across the same problem. One needs to build with -DCLARABEL_FEATURE_SERDE=on.
