Problem with variable coder

15 views (last 30 days)
Hello everybody, I have this problem when I run my program.
Undefined variable "coder" or class "coder.Project".
Undefined function or variable 'CC'.
Error in emlckernel
Error in emlckernel
Error in emlckernel
Error in emlcprivate
Error in codegen
I have checked my license and I get succesful returns and I have also execute these commands:
>> restoredefaultpath
>> rehash toolboxcache
>> savepath
Any idea?
Thanks in advance,
Javi

Show your code where you call coder. Is that in codegen.m? Show what you see when you type "ver" (except delete your license number.) Since this could be an installation issue, you can always call them on the phone for fast and free installation help.

From the output of your "ver" command, it seems like you do not have the MATLAB Coder or Simulink Coder products as part of your MATLAB installation. The error you are observing is likely due to this. Please consider installing MATLAB Coder or Simulink Coder in order to resolve the error.

Just down Matlab's version I can see "Coder Version 3.3"
Is not that enough?
Thanks for the answer,
Javi
