Bitcoin Compilation Issues: A Detailed Guide

As a fan of cryptocurrency, you naturally want to create and deploy your own version of the popular Bitcoin blockchain. However, compiling Bitcoin can be a difficult task due to its complex dependencies and strict licensing requirements. In this article, we will look at some common problems that arise when building Bitcoin with CMake and provide recommendations for overcoming them.

Error: Leveldb not found

The error message you received indicates that the Leveldb library is missing from your build path. The Leveldb database is a core component of Bitcoin, providing a lightweight alternative to traditional databases for data storage.

To fix this problem, you need to add the following directory to the CMAKE_CURRENT_SOURCE_DIR variable in the CMake configuration file (CMakeLists.txt) or use the --add_module option when compiling:

• CMake configuration file (CMakeLists.txt):

cmake_minimum_required(VERSION 3.10)
add_package(BitcoinLib)
target_include_directories(${CMAKE_CURRENT_SOURCE_DIR})
Leveledb::Leveledb

• Using CMake:

CMAKE_BUILD_TYPE=Release
cmake .. -DBUILD_EXTENSION=Leveldb

• Compile command:

cmake --build .

Common compilation issues and solutions

• Library Leveledb not found: Make sure that the Leveldb library is installed in your system’s PATH environment variable.

• CMake error (Leveldb not found):

• Check if you have the Leveldb development pack installed.

• Use CMake to build and link with Leveledb.

• There is no `Leveledb'' library:

• Reinstall theLeveledblibrary by runningapt-get install leveldb-dev(for Ubuntu-based systems) orbrew install leveldb(when using Homebrew).

• LibraryLeveledbnot found on Linux: Make sure that the Leveldb development package is installed for your Linux distribution.

Best Practices and Next Steps

• When building Bitcoin, always use the latest version of CMake to ensure compatibility with the latest dependencies.

• For a successful build, be sure to specify the correct path to theLeveledb’ library when compiling.

• Consider using a build system such as Meson or Scons for more flexibility and control over the build process.

By following these troubleshooting steps and best practices, you will be able to successfully compile and deploy your own version of Bitcoin. Good build!
