Link warning linking with nrf_dm library in Zephyr

[AndyM]

Here is a warning I get linking an application that uses nRF DM library
5/14] Linking C static library app\libapp.a
[6/14] Linking C executable zephyr\zephyr_pre0.elf
c:/toolchains/v2.1.1/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.exe: warning: C:/v2.1.1/nrfxlib/nrf_dm/lib/nRF52840/hard-float/libnrf_dm.a(libnrf_dm.obj) uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail

Any ideas how to get rid of it?

Thanks

Andy

Hi!

This is a typical warning that you shouldn't really need to worry about. For some more info you could for instance see here.  

There are different ways to get rid of it though, as you can see in the stackoverflow thread. Here is one suggestion made for nRF5SDK.

Are you using the default toolchain and compiler that comes with NCS 2.1.1?
