Includes from halconf.h

If I enable a part of HAL in halconf.h it works (for example, enable USB by #define HAL_USE_USB).
If I include another file to halconf.h and declare this define in it, but not in halconf.h, I got a link error.
Definions from enabled module available to my code, but object files with implementation didn't compiled.
Why is this happening? Is it possible to somehow get around?

I got this errors if #define HAL_USE_SERIAL_USB TRUE and #define HAL_USE_USB TRUE located in file included from halconf.h. If I declare this macros in halconf.h everything is ok.

The driver includes halconf.h so probably your macro is not taken or is overwritten.

I've noticed that even matters are commented out in the description halconf.h.
Code: Select all
#include "some_file.h" -- Some file contains real HAL_USE_SERIAL and HAL_USE_USB defines.
...
//#define HAL_USE_SERIAL_USB TRUE
//#define HAL_USE_USB TRUE
If I write this everything works. I assume that the decision to compile separate object files taken some simple parser that analyzes halconf.h and don't support #include and comments.

You can disable it in the Makefile.
USE_SMART_BUILD = no
