67 This is a GUI application built with GTK and C that queries stock performance data via an external API using cURL.

This project is primarily configured to be built and run on Windows using the MSYS2/MinGW UCRT64 environment.

• MSYS2: A software distribution and building platform for Windows. Download and install it from the official site.
• GTK 3 and Build Tools: These will be installed via the MSYS2 package manager.

Since this project uses local cURL libraries and a custom Makefile, the process is streamlined once the environment is set up.

1. Install MSYS2 and Dependencies:

   • Open the MSYS2 MinGW UCRT64 shell.

   • Install the necessary GTK 3 libraries and the build chain (gcc):

     pacman -S mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-gtk3

2. Organize Files:

   • Ensure all your project files (gui_app.c, api.c, Makefile, and the local curl/ folder) are in the same directory.

3. Compile the Application:

   • In the MSYS2 UCRT64 shell, navigate to your project directory.

   • Run the simple command to compile the application:

     make

   • (The Makefile handles finding the GTK libraries and linking the local cURL files.)

4. Run the Application:

   • Execute the compiled program directly using the included run target:

     make run
     # Alternatively:
     # ./gui_app.exe

• API Key: Ensure your API key is correctly configured within your source code (e.g., in api.c).
• SSL Certificate: The cURL configuration specifies an SSL bundle path. Ensure the file ./curl-ca-bundle.crt is present in the same directory as the executable.

While the Makefile is heavily customized for Windows, it may still work on Linux/macOS if you adjust the PKG_CONFIG_PATH line for your system's GTK installation and correctly point to a local cURL library build.

General Steps: 1. Install gcc, gtk+-3.0-dev, and libcurl-dev. 2. Comment out the hardcoded PKG_CONFIG_PATH in the Makefile. 3. Ensure your local cURL directory (./curl/) is correctly structured or link against the system libcurl.
