How to Quickly Set Up a Full Linux C/C++ Development Environment

Prerequisites

Select a Debian‑based distribution such as Ubuntu (desktop or server) or Debian. Allocate at least 50 GB disk space, 4 GB RAM (8 GB recommended), and 4 CPU cores. For virtual machines use bridged networking.

1. Install the compiler toolchain

sudo apt update
sudo apt install build-essential
gcc --version
g++ --version
make --version

The build-essential package provides gcc, g++, and make.

2. Install a code editor

2.1 Vim (terminal)

sudo apt install vim

Basic Vim shortcuts: i (insert), Esc (normal mode), :wq (save & quit).

2.2 Visual Studio Code (GUI)

Download the .deb package from https://code.visualstudio.com/ and install:

sudo dpkg -i code_*.deb
sudo apt-get -f install   # fix missing dependencies

Recommended extensions: C/C++ , Code Runner , CMake Tools . Open a project with

code .

2.3 CLion (optional IDE)

Download the .deb installer from https://www.jetbrains.com/clion/ and follow the installer prompts. A free student license is available.

3. Compile and run programs

3.1 Simple C program

#include <stdio.h>
int main() {
    printf("Hello, World!
");
    return 0;
}

gcc hello.c -o hello
./hello

3.2 Simple C++ program

#include <iostream>
using namespace std;
int main() {
    cout << "Hello, C++!" << endl;
    return 0;
}

g++ hello.cpp -o hello
./hello

3.3 Common troubleshooting

gcc: command not found

– reinstall the toolchain with sudo apt install build-essential.

Missing headers ( stdio.h, iostream) – reinstall with sudo apt reinstall build-essential.

4. Debugging tools

4.1 GDB

sudo apt install gdb
g++ -g hello.cpp -o hello   # compile with debug symbols
gdb ./hello

run

– start the program. break main – set a breakpoint at main(). next – step over the current line. print var – display the value of var.

4.2 Valgrind (memory checking)

sudo apt install valgrind -y
valgrind ./your_program

Look for “All heap blocks were freed” (no leaks) or “definitely lost” / “indirectly lost” messages indicating memory leaks.

5. Build automation

5.1 Makefile (small projects)

# Define compiler
CC = gcc
# Compiler flags
CFLAGS = -Wall -g

all: main

main: main.o func.o
	$(CC) $(CFLAGS) -o main main.o func.o

%.o: %.c
	$(CC) $(CFLAGS) -c $<

clean:
	rm -rf *.o main

Run make to build and make clean to remove generated files.

5.2 CMake (larger or cross‑platform projects)

sudo apt install cmake -y

# CMakeLists.txt
cmake_minimum_required(VERSION 3.10)
project(MyProject)
add_executable(main main.cpp func.cpp)

mkdir build && cd build
cmake ..
make

CMake generates appropriate Makefiles for the target platform.

6. Terminal enhancement

6.1 Install Zsh and Oh‑My‑Zsh

sudo apt install zsh
chsh -s $(which zsh)
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

6.2 Powerlevel10k theme and useful plugins

# Powerlevel10k theme
git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/.oh-my-zsh/custom/themes/powerlevel10k
echo 'ZSH_THEME="powerlevel10k/powerlevel10k"' >> ~/.zshrc
source ~/.zshrc

# Autosuggestions plugin
git clone https://github.com/zsh-users/zsh-autosuggestions ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions
# Syntax highlighting plugin
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting
# Enable plugins
sed -i 's/plugins=(git)/plugins=(git zsh-autosuggestions zsh-syntax-highlighting)/' ~/.zshrc
source ~/.zshrc

7. Git version control

7.1 Install Git

sudo apt install git -y
git --version

7.2 Repository initialization and configuration

# Initialize repository
git init
# Set global identity
git config --global user.name "Your Name"
git config --global user.email "[email protected]"

7.3 Basic workflow

# Stage changes
git add .
# Commit
git commit -m "Initial commit"
# Check status
git status
# View history
git log

7.4 Remote operations

# Add remote (replace with your repository URL)
git remote add origin [email protected]:yourname/yourrepo.git
# Push initial branch
git push -u origin master
# Clone a repository
git clone [email protected]:yourname/yourrepo.git

These commands cover the essential Git operations for solo or collaborative C/C++ development.
