Error while trying to build example project using command prompt and GCC

[Jordannel]

Hi there,

I've been trying to figure this one out for a day or so now with no luck.

I'm successfully able to build and program using Segger Embedded Studio, but I would prefer to work in Eclipse.

I have followed this tutorial while trying to get everything setup and working in Eclipse: https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/development-with-gcc-and-eclipse

The problem I'm having is that I am unable to get any example projects to successfully build with the 'make' command through the command prompt.

The error I am getting is as follows:

C:\nRF5_SDK_15.3.0_59ac345\examples\peripheral\blinky\pca10056\blank\armgcc>make

I did find this post in the Nordic Dev Zone where the person asking for help had a very similar error: https://devzone.nordicsemi.com/f/nordic-q-a/37631/trying-to-build-project-with-gcc-but-comes-to-this-error-message

I have tried all the suggestions in that post which seemed to have to work, but they haven't worked for me.

Any help would be greatly appreciated.

Thanks

Jordan

I forgot to mention that I'm currently using the "nRF5_SDK_15.3.0_59ac345" version of the nRF SDK and the "8 2018-q4-major" (8.2.1) version of GNU Tools.

If you want to work with Eclipse & GCC, follow this blog http://embeddedsoftdev.blogspot.com/p/ehal-nrf51.html

most of Nordic tutorial about it don't work.

Thanks very much for that blog reference  Nguyen Hoan Hoang

I did however stumble across another Tutorial which helped me solve my problem: https://www.disk91.com/2017/technology/hardware/discover-nordic-semi-nrf52832/

I'm not sure if this is common knowledge, but I didn't realize that you also have to download the 'GNU-Make Utility' and 'GNU-Core Utilities' and then merge them with your GNU Tools folder. After doing this I was able to successfully build the nRF "blinky" example through the command prompt with the "make" command. I also changed the GNU Tools version I was using from "8.2.1" to "7.3.1", as I was getting an additional error when using 8.2.1.

For anyone who might be getting a similar error, my working setup is as follows:

Operating System: Windows 7 64-Bit

GNU Toolchain version and path: "C:\nRF52\GNU Tools ARM Embedded\7 2018-q2-update\"

nRF SDK version and path: "C:\nRF52\nRF5_SDK_15.3.0_59ac345\"

Included in System Environment Variable "Path": C:\nRF52\GNU Tools ARM Embedded\7 2018-q2-update\bin;

Makefile.windows: 

GNU_INSTALL_ROOT := C:\nRF52\GNU Tools ARM Embedded\7 2018-q2-update/bin/
GNU_VERSION := 7.3.1
GNU_PREFIX := arm-none-eabi
