using treat_inlines causes include files under support folder to break

Ceedling:: 0.31.1
Unity:: 2.5.4
CMock:: 2.5.4
CException:: 1.3.3

I have a file "DSP280x_Device.h" under the test/support/ folder.

If I use treat_inlines and mock "gpio.h" (which includes "DSP280x_Device.h"), the generated "gpio.h" file under the mock folder will add the test/support/ path, which causes the compile to fail.

In file included from build/test/mocks/mock_gpio.h:6,
                 from test/test_can_runtime.c:12:
build/test/mocks/gpio.h:2:10: fatal error: test/support/DSP280x_Device.h: No such file or directory
    2 | #include "test/support/DSP280x_Device.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

You will need to give a bit more than that, because here it seems like your compiler and build system cannot find the "DSP280x_Device.h" and not a CMock failure.

Here is a sample gpio.h

#ifndef GPIO_H
#define GPIO_H

#include <stdint.h>
#include <stdbool.h>
#include "DSP280x_Device.h"
#include "DSP280x_Examples.h"

static inline bool gpio_get(uint16_t gpio_id)
{
    /* code here */
}

void GPIO_init_Startup( void );

#endif  /* GPIO_H */

Which will turn into this generated file in the mock folder:

#include "../../CodeVault/inc/sys/DSP280x_Examples.h"
#include "test/support/DSP280x_Device.h"
_Bool 

                  gpio_get(uint16_t gpio_id);

void GPIO_init_Startup( void );

For some reason, the compiler cannot find "test/support/DSP280x_Device.h" but it can find "DSP280x_Device.h". Is there something wrong with my project.yaml maybe?

I am attaching an example that fails. But if you remove the treat_inlines from the project.yaml it works.

inline_test.zip

Is this related to the use_test_preprocessor setting? If I set it to FALSE, then it seems to compile. Is this correct?

[radu-toma]

I see similar issues and behaviour. Seems that

:use_test_preprocessor: FALSE

somehow works.
