Building CUDA in platformio-ide-terminal

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?

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"

To get it working, I changed it path to: `C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\Hostx64\x64`. – afp_2008 Oct 26 '19 at 17:44

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

Try the new cross-platform PowerShell https://aka.ms/pscore6

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
hello_world.cu

PS C:\Users\falah\Downloads\cuda_by_example> .\a.exe
Hello, World!
PS C:\Users\falah\Downloads\cuda_by_example>

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.
