Bitcoin: Bitcoin compilation keeps failing

Fill Issues with Bitcoin: The Complete Guide

As a cryptocurrency enthusiast, it’s natural to want to build and deploy your own version of the popular Bitcoin blockchain. However, compiling Bitcoin can be a daunting task due to complex dependencies and strict licensing requirements. In this article, we’ll look at some of the common issues we encounter when building Bitcoin with CMake, and provide guidance on how to overcome them.

Error: Leveldb not found

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

To fix this issue, you will need to add the following directory to the CMAKE_CURRENT_SOURCE_DIR variable in your 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=Run

cmake .. -DBUILD_EXTENSION=Leveledb

Build command:

cmake --build .

Common compilation problems and solutions

  • Leveledb library not found:

    Make sure that the Leveldb library is installed in your system's PATH environment variable.

  • CMake Error (Leveldb not found):
  • Check that the Leveldb build package is installed.
  • Use CMake to build and link with Leveledb.
  • Leveledb library missing:
  • Reinstall the Leveledb library by running "apt-get install leveldb-dev" (for Ubuntu systems) or "brew install leveldb" (if you are using Homebrew).
  • Leveledb library not found on Linux: Make sure that the Leveldb build 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 the Leveledb` library when compiling.
  • Consider using a build system such as Meson or Scons for more flexibility and control over your build process.

By following these troubleshooting steps and best practices, you should be able to successfully compile and deploy your Bitcoin build. Happy building!
