💡 Getting Started – C GUI Calculator

Welcome! This guide will help you get up and running with the C GUI Calculator built using GTK+ 3. Follow the platform-specific instructions below to clone, install dependencies, compile, and run the calculator.

📦 Prerequisites

Before compiling, ensure the following packages are installed:

gcc – C compiler
pkg-config – Compiler and linker configuration helper
libgtk-3-dev – GTK+ 3 development files

See the Requirements Guide for full details and installation commands for all platforms.

🚀 Setup & Compilation

🔹 1. Clone the Repository

git clone https://github.com/rafisarkar0128/c-gui-calculator.git
cd c-gui-calculator

🔹 2. Install GTK and Dependencies

📍 Linux (Debian/Ubuntu)

sudo apt update
sudo apt install gcc pkg-config libgtk-3-dev

📍 Fedora/CentOS/RHEL

sudo dnf install gcc pkgconf-pkg-config gtk3-devel

📍 macOS (Homebrew)

brew install gcc pkg-config gtk+3

⚠️ Additional setup like XQuartz may be required to run GUI apps on macOS.

📍 Windows (MSYS2)

pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-pkg-config mingw-w64-x86_64-gtk3

💡 Alternatively, you may use Code::Blocks with proper GTK+ configuration.

🔹 3. Compile the Project

gcc -o calculator main.c `pkg-config --cflags --libs gtk+-3.0` -lm
./calculator

🧠 -lm is included for linking math functions if your calculator uses them.

🛠️ Troubleshooting

Ensure your system’s package manager is up to date.
If pkg-config reports missing paths, verify GTK installation.
Windows users: Make sure MSYS2’s shell uses the mingw-w64 environment, not the default msys.
