Hi, I am following your blog post, Ruuvi Firmware – Part 1: Sleep, to familiarise myself with the toolchain and programming. I am encountering following error "‘__vfprintf.h: No such file or directory’ " when I build the Ruuvi firmware c code as mentioned in the blog. I am exploring the internet to fix this issue. Meanwhile, I thought I would also post it here, if someone encountered the same error before and has a solution to share, it can save some time for me.
Thanks in advance.
Hi @BleTagLearner ,
Thanks for your message, maybe @otso has idea about this error.
Hello,
Have you installed the nRF15.3 SDK and ARMGCC as per Nordic’s instructions?
Personally I symlink the SDK, that way I can have many different projects without duplicating SDK files. e.g.
-projects
--MyRuuviProject
---nRF5_SDK15.3 (symlink)
--nRF5_SDK15.3 (actual folder)
Yes, I have installed the nRF5_SDK_15.0.0_a53641a and ARMGCC.
From one of the forums, I learned that some C files are deprecated in the latest Segger version (version 8), and it was recommended to install an older version, specifically version 5. I was able to download Segger for Nordic V5.68 from the Nordic tutorial on manual installation using the following link:
Segger for Nordic Version 5.68
Now, the code compiles successfully.
Thank you for your prompt response and for the idea of 'symlinking the SDK.
Happy to hear that code compiles now
