Compiling Bitcoin-Qt as an .exe on Ubuntu

Bitcoin-Qt is a popular open-source implementation of the Bitcoin protocol, and compiling it on your Ubuntu machine can be a bit more involved than usual. However, I’ll guide you through the process step-by-step.

Prerequisites

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

• Python 3: Bitcoin-Qt requires Python 3.x. If you are using an earlier version of Python, you may need to install it manually.

• Make: Make is a prerequisite for compiling Bitcoin-Qt from source.

• G++

  : G++ (GNU Compiler Collection) is required for building C++ code.

Step 1: Install necessary packages

To compile Bitcoin-Qt on Ubuntu, you’ll need to install the following packages:

• python3: This is required for compiling Python code.

• make: This package provides the make command to build and compile projects from source.

• g++: This package provides the g++ compiler.

You can install these packages using the following commands:

sudo apt-get update

sudo apt-get install python3-dev make g++-4.x 




For Ubuntu 16.04 (Xenial) or later

If you are using an earlier version of Ubuntu, you may need to install the python3-pip package instead.

sudo apt-get update

sudo apt-get install python3-pip

Step 2: Create a Bitcoin-Qt build directory

Once you’ve installed the necessary packages, create a new directory for your Bitcoin-Qt compilation:

mkdir bitcoin-qt-build

Change into this directory:

cd bitcoin-qt-build

Step 3: Compile Bitcoin-Qt from source

Now that you have all the prerequisites installed and the build directory set up, you can compile Bitcoin-Qt from its README.md file or by using autogen.sh and then configure. We’ll use the latter method here.

• Edit the configure script:

sed -i 's/
CC = gcc 
GCC is used for compiling C code/' config.mk

This will update the CC variable to include gcc, which is the default compiler on Ubuntu.

• Compile Bitcoin-Qt using autogen.sh and then configure:

./autogen.sh

From ./configure -with

These commands will compile Bitcoin-Qt from source using the autoconf and automake build systems.

Step 4: Build and Install Bitcoin-Qt

Once you’ve compiled Bitcoin-Qt, you’ll need to build it into an executable file. You can do this by running:

make -f makefile .build

This command will compile the Bitcoin-Qt code and create an executable file in the build/ directory.

Step 5: Convert Bitcoin-Qt to an .exe

To convert the compiled Bitcoin-Qt executable into a Windows-compatible .exe file, you’ll need to use a tool like PyInstaller or Wine. I’m going to assume you’re using PyInstaller here.

• Install PyInstaller:

sudo apt-get install python3 installer

• Convert Bitcoin-Qt to an .exe:

pyinstaller --onefile bitcoin-qt.py

This command will convert the compiled Bitcoin-Qt executable into a standalone Windows application (.exe).

Troubleshooting

If you encounter any issues during the compilation process, here are some troubleshooting steps:

• Check for dependencies: Ensure that all dependencies required by Bitcoin-Qt are installed.

• Verify Python version: Double-check that your Python installation is compatible with Bitcoin-Qt (version 0.10.x or later).

• Use make dist instead of make -f makefile.build: If you encounter issues compiling the executable, try using make dist instead of make -f makefile.build.

Conclusion

Compiling Bitcoin-Qt on Ubuntu can be a bit more involved than usual, but with these steps, you should be able to successfully compile and install it. If you encounter any issues during the process, feel free to ask for help or consult online resources.

I hope this helps!
