cpufreq directory does not exist in WSL2

[jinbeom]

while I have followed instructions (https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/linux/build_instructions.md)

I got error when I hit `out/Default chrome` like below

I figure out cpufreq directory does not exist in cpu0 directory. To solve I install cpufrequtil but not worked to me

this is my wsl version

ubuntu@DESKTOP-VGNF0O2:~/chromium/src$ uname -r

5.4.72-microsoft-standard-WSL2

how to I run chrome??

WSL2 is not a supported configuration for building or running Chromium. Unless you can find someone else who is running it you'll have to solve the problems yourself. Even if you find a way to make it run, your changes may not be merged into the main repository because it's not a supported configuration.

It is a ciopfs issue. It uses the kernel default ulimits upon mount creation.

https://bugs.chromium.org/p/chromium/issues/detail?id=1188668

The usual quick fix methods to up ulimits probably are not going to help with WSL2. You might try creating a mount helper.

https://askubuntu.com/questions/663263/how-to-increase-limits-for-processes-created-from-fstab

The easier solution IMO is to virtualize an actual Linux install under VirtualBox, HyperV, etc. instead of using WSL2.
