I found these 2 threads here and here, but my problem is specific to vscode. I can compile and run test using cargo build and cargo test in terminal without a problem, and the program cc can be found at /usr/bin/cc.

$ which cc
/usr/bin/cc

My problem is when each time I edit and change the source code e.g. test case, I need to explicitly execute the command cargo test in terminal. Then, pressing Run test button inside vscode IDE would work. Otherwise, vscode will throw error: linker cc not found.

This problem seems to me that vscode does not sourcde .profile, where there exist the steps to activate rust env setting.

# rust env
. "$HOME/.cargo/env"

export LIBCLANG_PATH=/usr/lib/llvm-21/lib/libclang.so

However, I am not sure where to configure to fix this error in vscode. I attempted to add related setting to ~/.config/Code/User/settings.json, but it does not work.

"terminal.integrated.env.linux": {
    "PATH": "${env:PATH}:/usr/bin/",
    "LIBCLANG_PATH": "/usr/lib/llvm-21/lib/libclang.so"
}

How should I fix this error? Thanks.
