GPS SUPL dependancy issue

To fix the issue, I change the kconfig file under the supl directory:

config SUPL_CLIENT_LIB
	bool "SUPL Client library"
	# depends on NEWLIB_LIBC (COMMENTED OUT)
	help
	  A library for accessing A-GNSS data using the SUPL protocol.

Hi,

Have you modified your project configuration file prj.conf in NCS v2.7.0 compared to what you posted in your initial question? If yes, could you send it?

Can you provide working prj.conf that you used in NCS v2.6.1?
Can you provide your build command, build\zephyr\.config file, and full build log when you used NCS v2.7.0?
You can upload files by clicking on Insert -> Image/video/file -> Upload.

Best regards,
Dejan

Hi dejans ,

Thanks for getting back to me.

When using v2.6.1 in the nordic workplace (ie the one located /opt/nordic/ncs/v2.6.1/nrf), the GNSS sample works with SUPL with the addition of these in the KCONFIG:

CONFIG_GNSS_SAMPLE_SUPL_HOSTNAME="supl.google.com"
CONFIG_GNSS_SAMPLE_ASSISTANCE_SUPL=y
CONFIG_NEWLIB_LIBC=y

I also tried v2.7.0 and got:

warning: SUPL_CLIENT_LIB (defined at /Users/saubin/Desktop/xws/nrf/lib/supl/Kconfig:7) has direct dependencies NEWLIB_LIBC with value n, but is currently being y-selected by the following symbols:
 - GNSS_SAMPLE_ASSISTANCE_SUPL (defined at /Users/saubin/Desktop/xws/agmuster/lib/gps/Kconfig:107), with value y, direct dependencies <choice> (value: y), and select condition <choice> (value: y)

error: Aborting due to Kconfig warnings

I find the warnings very weird since I am setting CONFIG_NEWLIB_LIBC=y. The app is based on the NCS GNSS example, where the GPS logic is converted into a library.

Is there any way to check CONFIG_NEWLIB_LIBC is being assigned to y or if there are any other places in the code CONFIG_NEWLIB_LIBC is being forced to n?

Thanks for taking the time!

Hi,

Can you provide more information about your application? Is it based on any of the NCS samples?

[quote user=""]I have not had these problems outside of v2.6.1, could it be an issue with the current firmware?[/quote]

Have you tried using other NCS versions? Did your application work in any other NCS version except for v2.6.1?
