Troubles in compiling pc-ble-driver v4.1.2 for Python project with nRF52840 dongle

[Fabio Ballanti]

Hi,

As many of you, I'm tryng to compile pc-ble-driver (v4.1.2) found in https://github.com/NordicSemiconductor/pc-ble-driver/tree/v4.1.2, just to see how the code works and to re-use some parts in a Python project that I'm developing using the nRF52840 Dongle.

The Operative System is Windows 10 64-bit.

I've completed successfully the following steps Driver installation, Driver validation, Installing tools, Installing dependencies until facing troubles in Compiling pc-ble-driver on Windows:

- First problem encountered when Installing vcpkg dependencies: from the System Environment, I had to delete VCPKG_ROOT variable (previously set in the step 5 of Installing dependencies on Windows) and leave only the vcpkg correct link in path variable; after that I was able to install the vcpkg dependencies

mkdir build
cd build
vcpkg install asio
vcpkg install catch2
vcpkg install --head spdlog

- Second problem encountered at point "CMake Select the Visual Studio compiler to use according to this article: Build C/C++ code on the command line": (here I'm asking if someone can help me)

in this section, the System Environment variables CC and CXX were set  for MSVC compiler, and the cmake answer is as follow:

PS C:\Users\Fabio\Documents\nRF52840_Dongle\pc-ble-driver-4.1.2\build> cmake -G Ninja ..

So, long story short, I'm blocked: Can any one please help me?

P.S. As a completion, but don't think is part of the problem, "gcc-arm-none-eabi-9-2020-q2-update-win32" was installed and 

 the `Mass Storage Device` was disable (using regedit ), as described in Driver installation

Thank you.

Hello Fabio,

This seems to be an issue with your cmake configuration and c compiler, rather than a problem with the pc-ble-driver.

I've completed successfully the following steps Driver installation, Driver validation, Installing tools, Installing dependencies until facing troubles in Compiling pc-ble-driver on Windows:

Could you tell me, do you intend to use the pc-ble-driver, or the pc-ble-driver-py? From the title of your ticket, I assume you would like to use the pc-ble-driver-py. If this is the case, please follow its specific installation guide, from the main repository readme.
If you are intending to use the pc-ble-driver, we will continue with the debug of the above: Could you then list the specific steps ( with commands, if possible ) that you used to get to this error in the installation? Ideally, if you create it as a .bat file with the commands I can attempt to replicate it in a mint virtual Windows machine, to easier debug the issue. Alternatively, if you could list the tutorial steps that you followed ( and which tutorial you followed, in which order ), that is also an alternative.

Looking forward to resolving this issue together!

Best regards,
Karl

Hello Karl,

Yes, I will also try pc-ble-driver-py as you recommended (and probably write a Q&A for that):

Karl Ylvisaker said:

please follow its specific installation guide, from the main repository readme.

But for the moment, let's proceed with pc-ble-driver v4.1.2.

For me it's more simple writing you the steps and the code used as reported in Git Hub at NordicSemiconductor/pc-ble-driver, using Power Shell:

STEP 1 - Driver Installation and Driver Validation as reported here

STEP 2 - Installing Tools as reported here 

STEP 3 - Installing dependencies on Windows as reported here: 

• Download Visual Studio 15 or later version and install.(in this step I've installed even Visual Studio 2015 and Visual Studio 2019)
• Install Chocolatey. Install with cmd.exe (Run as administrator)

Using Power Shell launch the following commands:

PS C:\WINDOWS\system32>  Get-ExecutionPolicy
AllSigned
PS C:\WINDOWS\system32> Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Then add the Chocolatey location to the PATH

• Install Git.

PS C:\WINDOWS\system32> choco install -y git  

• Install CMake.

PS C:\WINDOWS\system32> choco install -y cmake

Then add the CMake location to the PATH

• Install vcpkg.

PS C:\WINDOWS\system32> cd ..
PS C:\WINDOWS> cd ..
PS C:\> git clone https://github.com/Microsoft/vcpkg.git
PS C:\> cd vcpkg
PS C:\vcpkg> git checkout tags/2020.04
PS C:\vcpkg> .\bootstrap-vcpkg.bat

Then add the vcpkg location to the PATH

Fabio Ballanti said:

leave only the vcpkg correct link in path variable

STEP 4 - As described on the GitHub page, those steps are needed only if you want to compile your own connectivity HEX files

• Install ninja.

PS C:\> choco install -y ninja

• Download and install GNU Embedded Toolchain for Arm here

Then add the location in the Environment Variable GNUARMEMB_TOOLCHAIN_PATH 

• Install Python and pip, and then install nrfutil

PS C:\> pip install nrfutil

STEP 5 - Compiling pc-ble-driver from source

• Install vcpkg dependencies.

PS C:\> cd C:\nRF52840_Dongle\pc-ble-driver-4.1.2
PS C:\nRF52840_Dongle\pc-ble-drive-4.1.2r> mkdir build
PS C:\nRF52840_Dongle\pc-ble-driver-4.1.2> cd build
PS C:\nRF52840_Dongle\pc-ble-driver-4.1.2\build> vcpkg install asio
PS C:\nRF52840_Dongle\pc-ble-driver-4.1.2\build> vcpkg install catch2
PS C:\nRF52840_Dongle\pc-ble-driver-4.1.2\build> vcpkg install --head spdlog

• CMake Select the Visual Studio compiler to use according to this article: Build C/C++ code on the command line

Fabio Ballanti said:

in this section, the System Environment variables CC and CXX were set  for MSVC compiler

PS C:\nRF52840_Dongle\pc-ble-driver-4.1.2\build> cmake -G Ninja ..

At this point I've encountered the problem described above...

Thank you!

Regards,

Fabio

Hello Fabio,

Thank you for the very detailed walkthrough of your installation! - it is very helpful for me when debugging this.

Fabio Ballanti said:

Yes, I will also try pc-ble-driver-py as you recommended (and probably write a Q&A for that):

Great! That is a sound plan.

Fabio Ballanti said:

At this point I've encountered the problem described above...

A couple of questions to rule out some common pitfalls:
- Did you complete the Download and install the tools section of the Microsoft documentation, referenced in step 5?
- Could you run the following command in your PowerShell, and let me know what it outputs:  

cmake --version

If you could also run the following command, and copy-paste the contents of the "Generators" section, that would be helpful as well:

cmake --help

This might seem trivial, but having seen these outputs will help me in narrowing down the issue.
- Could you also share with me your system PATH and variables you have added to it? You mentioned earlier that you had to delete the vcpkg variable to be able to install the vcpkg dependencies - this sounds strange.

Looking forward to resolving this issue together!

Best regards,
Karl

Not properly: I've set only the vcpkg link in PATH: C:\src\vcpkg;

Hello Fabio,

Sorry for my late reply.
Did you succeed in getting the pc-ble-driver-py to work as expected?
I have tried to replicate your issue with the pc-ble-driver compilation on my end by following your detailed explanation, but unfortunately I am not encountering the same errors as you.

Could you run this command in a regular command prompt (not PowerShell):

"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -format Json

And post the output here?

Looking forward to resolving this issue together!

Best regards,
Karl

Hello Karl,

Thank you for your reply, don't worry if it took so long.

No, I didn't yet... when have a free spot I will go for it... in the meanwhile I've imported the pc-ble-driver-py library on my scripts and started working on advertising on BLE, and found other troubles

OK, here is the output:

C:\WINDOWS\system32>"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" -format Json
