- Fast: Written in 100% modern
C++17
using multi-threaded and asynchronous programming techniques. - A drop-in replacement for ElectronX/ElectrumX: The initial release of this server is 100% protocol-level compatible with the ElectronX/ElectrumX 1.4.2 protocol. Existing server admins should feel right at home with this software since installation and management of it is nearly identical to ElectronX/ElectrumX server.
- Cross-platform: While this codebase was mainly developed and tested on MacOS, Windows and Linux, it should theoretically work on any modern OS (such as *BSD) that has QtCore available.
Qt Core
&Qt Networking
libraries5.11
or above (I use5.13.2
myself).- A modern, 64-bit
C++17
compiler.clang
is recommended butG++
also works. MSVC on Windows is not supported (please useMinGW G++
instead, which ships with Qt Open Source Edition for Windows).
It's recommended you use Qt Creator.
- Get the latest version of Qt Open Source Edition for your platform.
- Point the Qt Creator IDE at the
Fulcrum.pro
file. - Set the build configuration to "Release". Hit Build. It should "just work".
A note for Windows users: Qt 5.13.2
(or above) with MinGW G++ 7.x.x
is the compiler/Qt kit you should be using. MSVC is not supported by this codebase at the present time.
If you have problems compiling, the most likely culprit would be your compiler not being C++17
compliant (please use a recent verson of GCC
or clang
on Linux, Apple's Xcode
on Mac, or MinGW G++ 7.x
on Windows).
The other likely culprit is the fact that at the present time I have included a statically-built librocksdb
in the codebase. There are versions of this library for Windows, Mac, and Linux included right in the source tree, and Fulcrum.pro
looks for them and links to them. Instructions are included within the Fulcrum.pro
project file about how to build your own static librocksdb
if the bundled one does not work on your system.
The code is more or less configured to assume a "little endian" architecture by default (which is what all Intel x86/x86_64 are). If you're on a big endian machine, on Linux it should just auto-detect that fact. However, on other OS's such as BSD, if you're on a big endian machine, you may need to uncomment this line from the .pro
file:
# DEFINES += WORDS_BIGENDIAN
This codebase will not compile correctly (or at all) using MSVC. Please use the MinGW
and/or G++
kit in Qt Creator to build this software.
If you have clang
on your system, configure the project to use it as the compiler preferentially over G++
. G++
works too, but clang
is preferred.
Everything should just work (I use MacOS as my dev machine).
Q: Why Qt? This isn't a GUI app!
A: Yes, I know. However, Qt is a very robust, cross-platform and fast application framework. You can use its "Core" library for console apps, servers, etc. It has great network support and other basic things a programmer needs to get stuff done.
Sure! Send BCH here:
