Error whilst compiling Blinky

jaredwolff · Dec 18, 2020

Open up powershell.exe in Adminstrator mode and run:

choco uninstall cmake
choco install -y cmake --version 3.18.5

Then delete your build directory and try again.

Hi @jaredwolff

Tried that, and cmake didn’t seem to be added to the PATH, so had to add it manually and now it reports as:

C:\nfed\nrf9160-feather\samples\blinky>cmake -version
cmake version 3.18.5

But I still get the same error as before:-

CMake Error at C:/nfed/zephyr/cmake/extensions.cmake:1457 (message):
  Assertion failed: The toolchain is unable to build a dummy C file.  See
  CMakeError.log.

mikcatta where are you running these commands? powershell.exe? You don’t have any other cmake installations before using choco correct?

jaredwolff · Dec 18, 2020

I will add, what are you using to do your edits? I’m starting to see that my setup is not working in standalone powershell.exe but in the shell provided by VSCode. (as that’s how I did my testing)

jaredwolff · Dec 18, 2020

Can you try installing cmake with cmd.exe instead?

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/getting_started/index.html#install-required-tools

It might be that there is some weirdness when using powershell.exe standalone. I have a build cooking away using standalone cmd.exe

Mmikcatta · Dec 18, 2020

@jaredwolff

I am running the commands from the Windows cmd prompt, is that OK?

I’ve done a search for cmake.exe and found the following:-

`C:>dir /s cmake.exe

jaredwolff · Dec 18, 2020

@mikcatta I will add you may have to delete the build directory before trying in cmd.exe. Hopefully this fixes your issues. I’ve updated the instructions to hopefully address this issue when building in standalone terminal.

Mmikcatta · Dec 18, 2020

@jaredwolff Didn’t work for me, but it’s getting late so will try again tomorrow.

jaredwolff · Dec 19, 2020

@mikcatta what does your root nfed directory look like?

jaredwolff · Dec 19, 2020

mikcatta hmm looks ok. So you’re still getting the “Cannot compile dummy file” error on both Linux and Windows?

What’s the version of your compiler?

Mmikcatta · Dec 19, 2020

Evening @jaredwolff

I’ve got a bit further on Linux, but not quite to point of compiling !

Both Win & Ubuntu report:

- The C compiler identification is GNU 9.2.1
-- The CXX compiler identification is GNU 9.2.1
-- The ASM compiler identification is GNU

Mmikcatta · Dec 19, 2020

I believe I have a compile on Ubuntu !

Had to follow these instructions on the Nordic site for the Python dependencies, which are ever so slightly different to the instructions on your site. [https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#installing-the-required-tools]

pip3 install –user -r zephyr/scripts/requirements.txt
pip3 install –user -r nrf/scripts/requirements.txt
pip3 install –user -r bootloader/mcuboot/scripts/requirements.txt

I am using CMake 3.18.5 on Ubuntu, but I am not sure that was the issue.

Mmikcatta · Dec 19, 2020

Hi @jaredwolff Just to clarify….

I have created a ~/.zephyrrc file which contains

export PATH=$PATH:/home/mike/cmake-3.18.5-Linux-x86_64/bin
export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
export GNUARMEMB_TOOLCHAIN_PATH="~/gnuarmemb"

I installed cmake-3.18.5 from source, so it installed it locally. Again not sure, that was the issue. The GNUARMEMB was installed into the directory ~/gnuarmemb

On first compile, I had to add the “-p” command, so ran west build -b circuitdojo_feather_nrf9160ns -p

Some of these steps may not be necessary, but it seems to compile a hex file now at least on Ubuntu. Next step will be to see if I can flash it from the VM or maybe in needs to be transferred to Windows for programming the board, but that’s tomorrow little game.

jaredwolff · Dec 20, 2020

Got it. I’m looking into utilizing the nRF Desktop SDK Manager. Since you have those already installed, it would make the most sense to use them. Stay tuned..

Mmikcatta · Dec 20, 2020

HI @jaredwolff

Apologises, I thought I’d have a go at compiling one of the main apps for the Feather at https://docs.jaredwolff.com/nrf9160-agps-sample.html

From the /home/mike/nfed/nrf/samples/nrf9160/nrf_cloud_agps, I’ve added the additional lines to the prj.conf, but when I try and compile it says:-

**/home/mike/nfed/nrf/samples/nrf9160/nrf_cloud_agps/prj.conf:61: warning: attempt to assign the value '"feather-"' to the undefined symbol NRF_CLOUD_CLIENT_ID_PREFIX**

Without that line, it compiles just fine. What I am doing wrong here please?

jaredwolff · Dec 20, 2020

mikcatta this example only works on newer versions of the nRF Connect SDK. What version are you using?

Mmikcatta · Dec 20, 2020

Hi @jaredwolf I was just following the instructions on your website, if that doesn’t work, can you clarify that on the site at the URL https://docs.jaredwolff.com/nrf9160-agps-sample.html ?

Mmikcatta · Dec 20, 2020

@jaredwolff I use the pre-built binary, can I set a custom APN for use with my O2/Telefonica SIM?

jaredwolff · Dec 20, 2020

mikcatta @jaredwolff I use the pre-built binary, can I set a custom APN for use with my O2/Telefonica SIM?

~~Unfortunately not.~~

mikcatta actually you should be able to set a APN if it doesn’t get set already. Have you tried without editing anything? Otherwise you can try something like this in LTE Link Monitor:

AT+CGDCONT="0,\"IPv4v6\",\"internet.apn\""

Whereas you can replace internet.apn with your APN.

Hope that helps!
