How to #define a header file name in Compiler settings?

<< < (2/2)

stahta01:
Found example code that worked for what you wanted.

In CB I have this set

--- Code: ---INCLUDE_FILE="stdlib.h"
--- End code ---
Edit: The CB Define can also be done without the double quotes as in

--- Code: ---INCLUDE_FILE=stdlib.h
--- End code ---
and it still works.

The program code had this below.

--- Code: ---#include <stdio.h>

#define STRINGIFY(X) STRINGIFY2(X)   
#define STRINGIFY2(X) #X

#include STRINGIFY(INCLUDE_FILE)

int main()
{
    printf("Hello world!\n");
    return 0;
}

--- End code ---

The shell is probably removing the "" from your string.
Try to use double or triple quotes.
Unfortunately we don't have a macro to preserve quotes. We only have REMOVE_QUOTES.
The other option seems to be to use escaping like \".
I'm not sure this is cross platform or if you need it to be cross platform.

@stahta01:

Your trick using STRINGIFY doesn't work with avr-gcc. This probably depends on the behavior of the c preprocessor and might be implementation dependent.

@oBFusCATed:

I tested several versions with double and triple " with and without preceding \ – nothing works. It seems to be impossible to define a double quoted -D macro. Also using ' to protect " doesn't help.

The only way I found, to do the trick is adding the folder which contains the header file to the -I options and define the macro as -DUART_CONFIG_H=<uart_config.h>, but that's not really conforming to the rules.

hanshuckebein:
I found the solution:

     -DUART_CONFIG_H=\\"uart_config.h\\"

oBFusCATed:
We need a ESCAPE_QUOTES macro...
