Simulink issue when trying to compile using "rapid accelerator" mode

I have some simulink files that I am trying to compile for quicker simulations. I am successful in both "normal" and "accelerator" modes; however, I cannot get it to work for "rapid accelerator"

1. I had IT install a more up-to-date GCC/G++ version that is 6.3.1. I am running matlab 2019a on red hat 7.

2. I compiled example code provided by mathworks. engdemo.cpp and explore.c both worked.

3. I exported LD_LIBRARY_PATH =/app/matlab/r2019a/bin/glnxa64/ without any luck as well. It also didn't appear to change the behavior at all.

Here are the error outputs. Thoughts?

a colleague had me do the following and it resolved the issue for me:

Under Simulink Configuration Parameters (ctrl+E) -> Simulation Target -> "Additional build information" -> Libraries add the following

/usr/local/MATLAB/R2019a/sys/os/glnxa64/libstdc++.so.6

NOTE: the install path and version of the library may vary with install/MATLAB version.
