errors of HDL Coder geneation in tutorial

I tried the matlab tutorial about HDL Code generation from matlab code. I used mlhdlc_sfir.m and mlhdlc_sfir_tb.m in the tutorial, and followed the instructions to set up a HDL Coder project. However, in the HDL Coder Advisor, when I runned the first step "Verify Floating-point Design", errors happened, it said "Error using buildInstrumentedMex". I checked the target build log as follows:

who can tell me how to fix it? Thanks!

"Is not recognized as an internal or external command, operable program or batch file"

Answer 1

[Walter Roberson]

What I would try is switching to a different compiler. lcc is old and buggy.

[David Fu]

I tried VC2010, but the result is the same.

The "cmd.exe is not recognized as an internal or external command, operable program or batch file" error usually means that you don't have C:\Windows\system32 (which is where cmd.exe resides) on your system PATH environment variable. Try fixing that, restart MATLAB and try again.
