nRF52 project in Eclipse doesn't see makefile defines

[Calvin]

Hey all,

I followed Vidar's excellent tutorial, and it works! I can compile without errors. However, when I try to walk through the project in Eclipse (the blinky example), a bunch of stuff is grayed out (for example:

#if LEDS_NUMBER > 0
static const uint8_t m_board_led_list[LEDS_NUMBER] = LEDS_LIST;
#endif

...is grayed out.

LEDS_NUMBER is defined in the makefile, and I followed the instructions for changing the CDT GCC Build Output Parser string. No joy.

If I define the LEDS_NUMBER explicitly in main.c, I get an error saying that it's been defined twice, because, well, it has been defined twice.

How do I make Eclipse see the makefile defines?

Hi, if you look at the GCC tutorial, devzone.nordicsemi.com/.../, under the chapter, Enable auto discovery of symbols, include paths and compiler settings, there is a description of the problem (Vidar told me that he thinks this is the problem). New patched makefile.common files are included in the bottom of the tutorial.

Hi Calvin, please include the build output as well. In addition, open the entries tab in the pre-processor view and expand the CDT GCC Build output Parser entry to see which symbols/include paths were included. Suspect the pre-processor symbols are missing (key symbol on entry indicates that it is partially working at least).
