solc exited with signal: 9 (SIGKILL) while compiling. How to compile a huge project successfully?

[TreapGoGo]

I am participating in a competitive audit and that is what I discovered: There is a terribly large amount of code in actual work, so that the compiler seems to fail.

The code I am auditing is composed of over 400 files, and it can't compile successfully in my WSL Ubuntu.

myubuntu@myubuntu:~/audit/24Jan-Arcadia-Sherlock/2023-12-arcadia-qpdk777/accounts-v2$ forge build
[⠢] Compiling...
[⠆] Compiling 367 files with 0.8.22
[⠆] Compiling 79 files with 0.7.6
[⠊] Solc 0.7.6 finished in 1.90s
Error: 
solc exited with signal: 9 (SIGKILL)
<empty output>

My computer is a brand new one with i5-13500HX, RTX4060 and 16GB RAM. It should be able to carry solc well.

I discover that the memory of my WSL ubuntu is not 16GB but 8GB, which might be not enough. Is this the reason why I can't compile? If so, how to enlarge the memory of WSL? If not, how can I compile a huge Foundry project successfully?

myubuntu@myubuntu:~/audit/24Jan-Arcadia-Sherlock$ free
               total        used        free      shared  buff/cache   available
Mem:         7989616      786980     7056744         432      145892     6998208
Swap:        2097152      775024     1322128

(or, maybe, linux thinks that solc comsumes too much resources and thus kills this thread???)

I have to admit that enlarging the memory limit is an effective approach! And it is not hard. I hope this could help others with the same issue.

All you need to do is to create a new file named .wslconfig in C:/Users/[YOUR USERNAME]/ with the content below input and saved:

[wsl2]
memory=15GB

Then restart your wsl with the command in your WINDOWS TERMINAL:

wsl --shutdown

Reopen your ubuntu, now it has a 15GB RAM, which can compile a lot of stuffs.

(god damn solc! i hope 15GB is enough for all projects, or one day i have to go to buy a 32GB RAM...)
