Source code typo. The function name is mexErrMsgTxt, not mxErrMsgTxt.

The error message is a linker error. It means that the compiled code has referenced a function called mxErrMsgTxt, but the linker cannot find any such function in the object code or libraries that are being linked.
So, look in the source code matlabasso.c for a call to mxErrMsgTxt and change that call to mexErrMsgTxt.

in the line 122 of matlabasso.c file replace mexErrMsgTxt with mxErrMsgTxt and mex compile successfuly.
