gmake: *** No rule to make target

I created a Simulink model and I am trying to upload to an Arduino, but I keep getting this error:

gmake: *** No rule to make target `W:/Desktop/Pixy2Trial/blocks/src/Pixy2Cam.cpp', needed by `Pixy2Cam.o'.  Stop.

That happens when W:/Desktop/Pixy2Trial/blocks/src/Pixy2Cam.cpp does not exist at that point.

[Abdul K]

Thanks for your reply. But the Pixy2Cam.cpp is in fact in the folder referred here.

[Walter Roberson]

If W:/Desktop/Pixy2Trial/blocks/src/Pixy2Cam.cpp does exist, then the other way that problem can occur is if the .mk file lists Pixy2Cam.cpp as being dependent on something else that got updated, so that the mk file thinks that it is necessary to regenerate the .cpp file .

Can you attach the .mk file W:\Desktop\Pixy2Trial\Pixy2CameraModel1_ert_rtw\Pixy2CameraModel1.mk ? You will probably have to zip it and attach the zip .

Also, please show the output of

ls W:/Desktop/Pixy2Trial/blocks/src

Thanks for your reply. I solved the issue by installed the MinGW compiler.

[Waseem Sajjad]

Hi Mr.Abdul, I am getting same error even when MinGW is installed. i am also working on matlab system block for pixy2 vision sensor. Did you succeed in your work.

[Abdul K]

I did solve this issue by installing MinGW. The model can be updated, built and the code uploaded to arduino, but I get this error when I am trying to run the model:

Error occurred while executing External Mode MEX-file 'ext_comm':

Failed to connect to the target. A time-out occurred while waiting for the connection response from the target. Possible reasons for the time-out:

a) The target is not switched on.

b) The target is not connected to your host machine.

c) The application for the model is not running on the target. You might have clicked the Stop button. If the Run button is not dimmed, click it. Otherwise, click the Build button, which downloads and runs your application on the target.

Hello：

Has the problem been solved? I had a similar problem using the MinGW64 compiler and the error message is as follows：

To me, deleting "slprj" folder in the working directory was a solution.
