CreateProcess: No such file or directory

PlatformIO IDE

I have been using PIO on a project for months and it worked great. I have been storing my project on github with just a gitignore of .pio and .vscode. My computer died and I have cloned the repo onto a new machine with newly installed vscode and pio. Now it won’t compile. I did a clean and then build from the bottom of vscode.

All of the files mentioned in the error exist in .cpp form. Here is the output …

xtensa-lx106-elf-g++: error: CreateProcess: No such file or directory

vscode version: 1.52.1
pio version: Core 5.0.4, Home 3.3.1

Is there something else I am supposed to be installing?

You might have a corrupted toolchain. Please remove the folder C:\Users\<user>\.platformio\packages\toolchain-xtensa completely and rebuild.

If in doubt, check if disabligg the antivirus makes a difference.

EDIT: corrected path.

There is no toochain-xtensa in .platformio. It only has appstate.json homestate.json packages penv platforms python3. Is this a clue to the problem?

I just started vscode and saw this …

Unable to resolve configuration with compilerPath: "C:/Users/mlap/.platformio/packages/toolchain-xtensa/bin/xtensa-lx106-elf-gcc.exe"

I don’t know if this happened before.

I just tried compiling with virus protection off and it didn’t change anything.

Is there some way to tell what file is missing that the error refers to?

I meant this path, I was missing a packages. The error message is telling you the same: The compiler is not there.

Thanks, that worked.

I’ve been running into this same issue and found that it’s caused by the build command length exceeding the 32k limit in Windows, this is discussed here: https://community.platformio.org/t/what-is-the-cause-of-this-build-failure/35089

As a desperate temporary workaround I just relocated my .platformio directory from my Windows user directory to c:\.platformio by setting the following environment variable:
PLATFORMIO_CORE_DIR=c:\.platformio

Because the path to this directory is used so many times in the build command this relocation seems to have shortened the command just enough to be under the 32k limit mentioned above. If I get more desperate I’ll shorten the directory name to c:\p

Yes this is a terrible sad hack, but hopefully the esp32 environment will be repackaged in the not too distant future.
