guix package -i vscodium


Optionally, VSCodium is also available as Flatpak (not recommended):

# install via flatpak
flatpak install flathub com.vscodium.codium


Tips for C/C++ programming

Visual Studio Code

  • Install C/C++ Extension (C/C++ for Visual Studio Code).
  • Edit c_cpp_properties.json:
    • Press ctrl-shift-p
    • Type C/C++, find the C/C++: Edit Configuration (JSON)
    • Add {$HOME}/.guix-profile/include/** to includePath.
    "configurations": [
            "name": "Linux",
            "includePath": [
            "defines": [],
            "compilerPath": "{$HOME}/.guix-profile/bin/g++",
            "cStandard": "c11",
            "cppStandard": "c++14",
            "intelliSenseMode": "gcc-x64"
    "version": 4


The C/C++ extension can’t be installed in VSCodium, you can use clangd extension. If the clangd was not found in the PATH the extension will download the binary file and will run it internally. (If you faced with any issue in running the clangd binary file please read the Foreign binary in Extensions in Troubleshooting part).

Improved Sandboxing for Flatpak

Because Flatpak packages run in a sand-boxed mode, they don’t have access to system paths like /var. since profiles are located in /var/guix/profiles path, they are not accessible for flapak packages by default and if you need to allow an application to have access to them, you need to provide access explicitly using --filesystem switch:

$ flatpak run --filesystem=/var/guix/profiles com.visualstudio.code



If VSCodium refuses to run, try loading it in debug mode. That usually gives at least some insight into what’s wrong:

code --verbose --log debug --disable-gpu

Foreign binary in Extensions

if you faced with any issue in running the binary files in the extension you can run one of the following options as solution. I see this issue for wakatime, cpptool and clangd extension binary files.

First of all run the ldd command on the binary file:

$ ldd path/to/binary/file

The problem related to ld-linux-x86-64.so.2 library that is not in the /lib64, so:

  1. You can create a symlink in this path, the ld-linux-x86-64.so.2 is one of the shared library of glibc. Install glibc and then create a symlink:
sudo mkdir /lib64
sudo ln -s /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib/ld-linux-x86-64.so.2 /lib64/
  1. You can patch the binary file and fix the library path:
patchelf --set-interpreter "$(patchelf --print-interpreter "$(realpath  "$(which sh)")")" path/to/binary/file

Visual Studio Code is unable to watch for file changes in this large workspace” (error ENOSPC)

When you see this notification, it indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. Before adjusting platform limits, make sure that potentially large folders, such as Python .venv, are added to the files.watcherExclude setting (more details below). The current limit can be viewed by running:

cat /proc/sys/fs/inotify/max_user_watches

The limit can be increased to its maximum by editing /etc/sysctl.conf (except on Arch Linux, read below) and adding this line to the end of the file:


The new value can then be loaded in by running sudo sysctl -p.


Since official solution provided by Microdoft is not available in Guix, we can’t modify the /etc/sysctl.conf manually. the alternative solution for Guix is to use sysctl-service-type instead and set custom value for fs.inotify.max_user_watches parameter.

(service sysctl-service-type
    (settings '(("fs.inotify.max_user_watches" . "524288")))))
