Compilation issue with gcc (11.4) #293

Hi all,

I see this issue when try to compile MPC with GNU compiler 11.4:

#10 912.6         /opt/mujoco-mpc/mjpc/../mjpc/spline/spline.h:106:9: error: expected unqualified-id before ‘const’

#10 912.6               |                                                                    )

But all is fine when I force cmake to use clang.

Thanks for opening this issue. This should be fixed soon. Currently, spline.h and spline.cc are not used in MJPC so you can comment out these files in the CMakeList if you need to build with gcc.

This issue should be resolved. Installation instructions (#324) now specify to build with clang.
