gmake: *** Error 1 when attempting to run Simulink with embedded Matlab Function

I am trying to run a Simulink model that has an embedded matlab function using the Pwelch function. However I get this error during the make process and I have no idea what the cause of the error is. Can you help?

Making simulation target "PCDS_SoI_Search_Process_Control_test1_sfun", ...

Answer 1

[Chris]

The source of the problem was found to be size limitations placed on the port dimensions for some signals in 'Model Explorer'. In some cases these limitations were being exceeded. It is a real challenge working with Variable-size signals within a Simulink Model that uses embedded Matlab functions.

Code size was not an issue.

Answer 2

[Walter Roberson]

I have not used Stateflow, but I am familiar with C.

The error being reported about .bss is about problems with static variables initialized to 0s. These would be variables outside the stack, and outside the heap too, as they would be statically sized in advance.

I do not know Simulink to give an example of what might be realistic in it, but an example more generally would be if code allocated a fixed-length buffer for input, perhaps as a global variable, then the buffer might be allocated to .bss .

The messages being given would correspond to there being a number of such variables being created in c5_d_sf_marshallOut and at least one of the variables is too large to represent. I do not know the details of the compiler you are using (Linux, isn't it?) so I cannot comment on what the limit might be. At least (4 Gigabytes minus 4 bytes) I would think.

You could try looking through the source for c5_d_sf_marshallOut and seeing if you can find any huge variables.

[Kaustubha Govind]

From a web search, I also found that this error usually occurs when the size of the code is very large (>2GB). I would recommend that you report this to MathWorks Technical Support, since the code being compiled is internally generated by the MATLAB Function block.

You can solve such problem by installing MinGW-w64 compiler!
