Installing GTK# for C# Development on Termux

Installing GTK# for C# Development on Termux

If you're a C# beginner looking to develop GTK# applications on Android Termux, you may have encountered some difficulties. The package gtk-sharp-3.0 is not available in the Termux repository, making it impossible to install GTK# using the standard package manager.

Prerequisites

Before we begin, make sure you have the following prerequisites installed:

• Termux app installed on your Android device
• Basic knowledge of C# programming language

Installing GTK# for C# Development on Termux

To install GTK# for C# development on Termux, we will need to follow these steps:

1. Install the mono package
2. Install the GTK# package
3. Verify the installation

Step 1: Install the mono package

Mono is an open-source implementation of the .NET Framework. It allows us to run C# applications on Linux-based systems like Termux. To install Mono, run the following command:

$ pkg install mono

Step 2: Install the GTK# package

Since the GTK# package is not available in the Termux repository, we will need to download and install it manually. Follow these steps to install GTK#:

1. Download the GTK# package from the Mono website: https://www.mono-project.com/download/stable/#download-lin-ubuntu
2. Extract the downloaded package using the following command:

$ tar xvf mono-complete-4.8.0.524.tar.xz

Note: Replace 4.8.0.524 with the version number of the package you downloaded.

1. Copy the extracted files to the Termux home directory:

$ mv mono-4.8.0.524 ~

1. Add the Mono and GTK# binaries to the PATH environment variable:

$ echo 'export PATH=~/mono-4.8.0.524/bin:$PATH' >> ~/.bashrc
$ echo 'export PKG_CONFIG_PATH=~/mono-4.8.0.524/lib/pkgconfig:$PKG_CONFIG_PATH' >> ~/.bashrc

1. Reload the .bashrc file:

$ source ~/.bashrc

Step 3: Verify the Installation

To verify that GTK# is installed correctly, run the following command:

$ gtk-demo

If GTK# is installed correctly, the GTK+ Demo window should appear.

Although the package gtk-sharp-3.0 is not available in the Termux repository, we can still install GTK# for C# development on Termux by downloading and installing it manually. By following the steps outlined in this article, you should be able to develop GTK# applications on your Android device using Termux.
