Hi Clement,
We've already raised the compile error concerns to the mathlib team. Obviously the error will stop your build. The "pol_est_asindp_i" function is defined both in 'asindp_i.h' and 'atandp_i.h'. For now you can simply comment out the #include statement for one of those two headers (in mathlib.h) to get a clean build for now.
I will raise the XDC issues to the team as well, thanks for bringing that to our attention.
Thanks,
Ian
