CMock with ThreadX

[Paul]

CMock doesn't seem to use the C pre-processor (cpp) when generating mocks.  For instance, ThreadX stupidly does a:

#define VOID void

and if there is a function with this as a return code, such as:

    VOID tx_application_define(VOID *first_unused_memory); 

CMock will try and create mocks that allow the user to return a type VOID.  The compiler will error out on this return of a void.

[Michael Karlesky]



That’s correct. CMock does not use the C preprocessor.

However,

1. CMock is configurable and can replace simple tokens with other types. In a simple case such as with a VOID define it could be configured to replace it as you need.
2. Ceedling does offer an option to run the C preprocessor on the input to CMock. Ceedling is a build tool built atop Rake specific to managing C test builds using Unity and CMock.
1. A few people have provided tutorials online for setting up a new project. Here’s an example: http://www.electronvector.com/blog/getting-started-with-ceedling-creating-a-new-project
2. The easiest way to get started is using a Docker image that includes all the tools and a gun C toolchain. See the last entry here: http://www.throwtheswitch.org/tools
