Unable to print long long

[ralphvn]

I am unable to print a long long. As a simple test I tried to print this:

			uint64_t long_num1 = 0x10000000000;
			printk("%llu\n", long_num1);

			int64_t long_num2 = 0x10000000000;
			printk("%lld\n", long_num2);

			int64_t long_num3 = 0x10000000000;
			printk("%lli\n", long_num3);

All three will print 0.

I am using version 2.5.0 and added this to my prj.conf, also tried it with only CONFIG_NEWLIB_LIBC=y to start with, don't know what I am doing wrong, float is also a problem at the moment:

CONFIG_NEWLIB_LIBC_NANO=n
CONFIG_NEWLIB_LIBC=y
CONFIG_MINIMAL_LIBC_LL_PRINTF=y

Hi,

Try to use printf instead of printk.

Also three times zero with printf.

I tried to add the settings and code you uploaded to the hello world example and flashed it to a nRF9160DK, SDK: v2.5.0.
It prints as expected, right?

*** Booting nRF Connect SDK v2.5.0 ***

1099511627776

Hello World! nrf9160dk_nrf9160

Here is a zip of the project:

6866.long_long_hello_world.zip

Can you test this and see if it works for you?

Yes this works, but still don't understand why it does not work when I add this to the aws_iot example project.

It is likely some configurations which differ between the projects.

In these situations, I like to compare build/zephyr/.config between the projects and look for differences which might be related to the issue at hand

Where it is not working there is this line in .config 

# CONFIG_NEWLIB_LIBC is not set

Where it is working the line is

CONFIG_NEWLIB_LIBC=y

So this is the problem I think but why is it not set after I added the line in the prj.conf?
