Building CUDA in platformio-ide-terminal - visual-studio

Question

I would like to be able to compile and build CUDA C source code provided here using Windows 10 Powershell. I have no issue doing this using x64 Native Tools Command Prompt for VS 2017.
However, I have tried several ways suggested online to get Powershell to work, but no success. The reason is I want to be able to build my cuda codes in Atom, the editor, using its package platformio-ide-terminal that loads a Powershell inside Atom. So, if I figure out how to setup Visual Studio 2017 Community in a Powershell, I edit my code in Atom and conveniently build them using its Powershell integration.
I tried to set the environment as follows but still nvcc cannot find the path to cl.exe.
Could someone kindly help me?

Answer 1

You can add the path to cl.exe to the environment variables:
control panel > view advanced system settings > Environment variables > Path > New.
Then add C:\Program Files (x86)\Microsoft Visual Studio\<year >\Community\VC\Tools\MSVC\<toolset>\bin\Hostx64\x64.
Or use this command for compile: nvcc x.cu .\chapter03\hello_world.cu -ccbin "C:\Program Files (x86)\Microsoft Visual Studio\<year >\Community\VC\Tools\MSVC\<toolset>\bin\Hostx64\x64"

Answer 2

Open a Windows Powershell and run the following commands at the prompt:

PS C:\Users\AFP\Downloads\cuda_by_example> & 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat' amd64

PS C:\Users\AFP\Downloads\cuda_by_example> nvcc .\chapter03\hello_world.cu

Automation
To automate this, create a file named nvcc_setup_for_powershell.ps1 and place the following two commands in it.
& 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat' amd64
$ENV:PATH="$ENV:PATH;C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\Hostx64\x64"
Write-Output "Configured PowerShell for NVCC Using Visual Studio 2019 Community x64"
$myshell = New-Object -com "Wscript.Shell"
$myshell.sendkeys("{ENTER}")
the last two commands is to simulate hitting enter button, adopted from here.
Open settings for platformio-ide-terminal under Core > Run Command place the path to the PowerShell script: & "C:\Path\To\Script\nvcc_setup_for_powershell.ps1".
You may need to open a PowerShell as administrator and run the following command
Set-ExecutionPolicy RemoteSigned
to allow you to execute nvcc_setup_for_powershell.ps1.
