error: quadprog: equality constraint matrix has incorrect column dimension

[ola]

I try to use lsqlin solver from optim package in c++ implementation. My code
is compiled, but returns an error when executing:
*error: quadprog: equality constraint matrix has incorrect column dimension*

I use octave 4.4.0 and optim 1.5.3.
Here is the code:  test_lsqlin.cc
<http://octave.1599824.n4.nabble.com/file/t373160/test_lsqlin.cc>  

I also tried to set the exact column dimension in the equality constraint
matrix (in my code matrix c), but it also doesn't work.
In my case matrices/vectors: A, b, Aeq, beq, x0 should be empty (x =
lsqlin(C,d,A,b,Aeq,beq,lb,ub,x0,options)).
Could you help me, what am I doing wrong?
