Clion configuring WSL tool chain

Preface

When we use CLion when , If installed locally Linux Subsystem （ Such as Ubuntu）, Want to use WSL Tool chain , but Credentials Has been an error , At this time, you can use the following solution .

If you haven't installed WSL, You can refer to the official tutorial ： Use WSL stay Windows Installation on Linux

Solution

In your Ubuntu In any directory , Copy the following into a script ( For example, the file name is ubuntu_setup_env.sh), And then execute .

#!/bin/bash
set -e

SSHD_LISTEN_ADDRESS=127.0.0.1
if [ -e "/dev/vsock" ]; then # in case of WSL2
                SSHD_LISTEN_ADDRESS=0.0.0.0
fi

SSHD_PORT=2222
SSHD_FILE=/etc/ssh/sshd_config
SUDOERS_FILE=/etc/sudoers

# 0. update package lists
sudo apt-get update

# 0.1. reinstall sshd (workaround for initial version of WSL)
sudo apt remove -y --purge openssh-server
sudo apt install -y openssh-server

# 0.2. install basic dependencies
# sudo apt install -y cmake gcc clang gdb valgrind build-essential

# 1.1. configure sshd
sudo cp $SSHD_FILE ${SSHD_FILE}.`date '+%Y-%m-%d_%H-%M-%S'`.back
sudo sed -i '/^Port/ d' $SSHD_FILE
sudo sed -i '/^ListenAddress/ d' $SSHD_FILE
sudo sed -i '/^UsePrivilegeSeparation/ d' $SSHD_FILE
sudo sed -i '/^PasswordAuthentication/ d' $SSHD_FILE
echo "# configured by CLion"      | sudo tee -a $SSHD_FILE
echo "ListenAddress ${SSHD_LISTEN_ADDRESS}"     | sudo tee -a $SSHD_FILE
echo "Port ${SSHD_PORT}"          | sudo tee -a $SSHD_FILE
echo "UsePrivilegeSeparation no"  | sudo tee -a $SSHD_FILE
echo "PasswordAuthentication yes" | sudo tee -a $SSHD_FILE
# 1.2. apply new settings
sudo service ssh --full-restart

# 2. autostart: run sshd
sed -i '/^sudo service ssh --full-restart/ d' ~/.bashrc
echo "%sudo ALL=(ALL) NOPASSWD: /usr/sbin/service ssh --full-restart" | sudo tee -a $SUDOERS_FILE
cat << 'EOF' >> ~/.bashrc sshd_status=$(service ssh status) if [[ $sshd_status = *"is not running"* ]]; then sudo service ssh --full-restart fi EOF

# summary: SSHD config info
echo
echo "SSH server parameters ($SSHD_FILE):"
echo "ListenAddress ${SSHD_LISTEN_ADDRESS}"
echo "Port ${SSHD_PORT}"
echo "UsePrivilegeSeparation no"
echo "PasswordAuthentication yes"

Be careful ： I annotated one more line of command in the script , As shown below . these C/C++ The compilation tool of is installed according to your own needs , The script does not force you to install , Install according to your own needs .

# 0.2. install basic dependencies
# sudo apt install -y cmake gcc clang gdb valgrind build-essential

Execute the script ：

sh ubuntu_setup_env.sh

verification

Do the following ssh Command connection verification （ Note that the port configured in the above script is 2222, User name is your own user name ）
