unfortunately, I have not experienced or seen reports of this behavior before. Please let me know if it happens again, and I'll try to reproduce it here.

Yes, I am, but I think Eclipse or CDT is doing something strange. After adding every symbol manually my project builds and no complaining. Then if I remove all the symbols, clear the CDT output parser entries for my project files, clear project and then build project somehow eclipse CDT finds all the symbols. This happens both in Eclipse mars and neon.

Did you use the makefile.common file from the tutorial in your build?

For my setup, it looks like the Build output Parser fails for all symbols, but manages to parse the include paths. This answer solves the problem, but then I have to add all the symbols by hand. Do you know if there are a more permanent solution to this problem?

Thanks, your screenshot did the trick!

No there are some others like RX_PIN_NUMBER, LED_3 the board related defines. I have the board flag set in the makefile and everything builds fine, but the IDE cant find them.

As a sidenote, the auto discovery of symbols doesn't work for me. I had to mirror all makefile includes into the eclipse includes.

Hi,

Is this the only define that Eclipse fails to resolve? In that case, have you set/removed 'CFLAGS += -DBOARD_PCA10040' from your makefile?

Manually defining the board in Eclipse should make Eclipse able to resolve the board specific symbols.

This symbol would be added automatically if auto discovery was working.

You can try cleaning your project, restart eclipse and rebuilding. Otherwise I'm out of ideas.

Thanks for sharing your settings. Unfortunately neither the tutorial settings nor yours are working on my project. And I cant see any flags "-E -P -v" in my console while building.

I assume you followed the "Enable auto discovery of symbols, include paths and compiler settings" section in the Nordic GCC tutorial?

I checked my settings and they are slightly different from the tutorial but its working for me. For "CDT GCC Build Output Parser" I have (arm-none-eabi-gcc)|([gc]++)|(clang)

For "CDT Built-in Compiler Settings Cross ARM" I have arm-none-eabi-gcc ${FLAGS} ${cross_toolchain_flags} -E -P -v -dD "${INPUTS}"

You can try compiling with these settings and see if they work for you.

Ohh well it doesn't work. The error in eclipse disappears but it wont build because im redefining.

I tried to define it again and now it works. As I mentioned in Mahesh's replay. It seems eclipse cant find the proper define as there are several. The FLAGS in the makefile are only for building. Is there a way to set these Flags in eclipse?

That's defined in "/components/softdevice/s132/headers/nrf_sdm.h" which is included in "softdevice_handler.h".

Add it to your include paths and include "softdevice_handler.h" in your main.

I tried it already. then it fails to find: "NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM"

RE: eclipse missing symbols

James Yu — Wed, 11 May 2016 15:37:20 GMT

I think its because it doesn't know which one to use. Do you have CFLAGS += -DBOARD_PCA10040 and ASMFLAGS += -DBOARD_PCA10040 in your makefile?

You can also just define it in your main.c:

#define NRF_CLOCK_LFCLKSRC      {.source        = NRF_CLOCK_LF_SRC_RC,              \
                                 .rc_ctiv       = 16,                               \
                                 .rc_temp_ctiv  = 2,                                \
                                 .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

It's a nrf_clock_lf_cfg_t struct: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.api.v2.0.0%2Fstructnrf__clock__lf__cfg__t.html

same here i can build and deploy, but the missing symbols in the IDE are annoying

You can use the external Makefile setup. It worked for me as far as building, flashing and debugging. I still have a problem with undefined symbols in the IDE but it has no effect on development.

RE: eclipse missing symbols

Bobbelkl — Wed, 11 May 2016 15:12:18 GMT

Yes i did, but its too outdates and the examples don't have the .project files anymore

Unfortunately I am not very familiar with eclipse. Are you following this Nordic tutorial? devzone.nordicsemi.com/.../

RE: eclipse missing symbols

Bobbelkl — Wed, 11 May 2016 14:49:51 GMT

thanks!

I have the path of "/examples/bsp/" in my includes guess eclipse doest know which define it should take. Any idea how to fix it?
