I have already cloned all git repos, projects, RIOT thirdparty_boards and thirdparty_cpu, with the same results.

I copied the Makefile.include from /RIOT/cpu/ and now I have this result while compiling the "hello-world" example:

I'm using this compiler:

which is recomended by Stefan in a precedent mail.

Hi Francisco,

during the work on c++11_compatibility I encountered similar errors such as:

In function `_sbrk_r': sbrkr.c:(.text._sbrk_r+0xc): undefined reference to `_sbrk'

since gcc > 4.7 is very picky these functions have to be set as exten in cpu/arm_common/syscalls.c to make them 'visible'

c.f. https://github.com/BytesGalore/RIOT/commit/83e04f8ad7da2d44ba0632b99eeecca07b2aa7ee https://github.com/BytesGalore/RIOT/commit/da413e79a8f30725a1a9626210eb17b7e8e3e07b

I hope that helps a bit.

Best regards, Martin

Hi Francisco!

I copied the Makefile.include from /RIOT/cpu/ and now I have this result while compiling the "hello-world" example:

/home/user/RIOT/projects/hello-world/../../thirdparty_boards/stm32f4discovery/bin/stm32f4discovery_base.a(board_init.o): In function `SystemInit': /home/user/RIOT/thirdparty_boards/stm32f4discovery/board_init.c:263: undefined reference to `RCC_APB1PeriphClockCmd'

<snip>

You should copy the include pathes from thirdparty_cpu/Makefile.base to thirdparty_cpu/Makefile.include. But I found at least two more missing defines in the thirdparty_cpu that would break the sixlowpan project for now, too.

I'm gonna fix these issues and make a pull request.

By the way: We're planning to merge all five repositories to simplify these things (probably next week).

Cheers, Oleg

Hi!

Here are my proposed fixes:

Regarding the not implemented hwtimer_set_absolute(), I guess that Marco or Stefan have already implemented it. Otherwise you could probably just take the code from Ala's branch for the stm32f103rey6:
