Errors in kinematics

The first photo for my kins .c showing these errors

The second photo for the same folder but I added include rtapi

(I just want you to know that my kins.c was generated by Matlab coder)

Can you attach the kins.c file? Does it look anything like a LinuxCNC kins file?

Is the .h file in the place that the .c file expects to find it?

i am sorry but all i understood is i have a (.c file) and i entered the command in terminal (sudo halcompile --install kins.c)
and i am not too good in linuxcnc ,i don't know if there is any missing steps
i will attach the kinematics file
many thanks..

I am afraid that looks nothing like a valid LinuxCNC kinematics file.

It could, possibly, be converted in to one. You would need both that file (inverse kins) and a forward kins equivalent.

linuxcnc.org/docs/2.7/html/motion/kinematics.html

well , i read the documentation and i knew that i have to implement forward and inverse kinematics with those functions
int kinematicsForward(const double *joint, EmcPose *world,
const KINEMATICS_FORWARD_FLAGS *fflags,
KINEMATICS_INVERSE_FLAGS *iflags)

int kinematicsInverse(const EmcPose * world, double *joints,
const KINEMATICS_INVERSE_FLAGS *iflags,
KINEMATICS_FORWARD_FLAGS *fflags)

and to avoid any problems i took the (c code ) of bi pod that was in the documentation and i added the functions but i still have problems"(
i will attach the code and the errors

thanks again for helping

You don't say what the error is that you see, but I think that perhaps your kins file fails to return a kinematics_type.

Have a look at trivkins for an example, there is a definied function that returns the kinematics type.
