Fulcrum 1.8.1

on GitHub

What's new:

This is a minor release of Fulcrum. The main change from the previous release is that the release binaries now include a statically-linked OpenSSL 1.1.1 library. This should improve compatibility of the release binary with various Linux systems. Upgrading from v1.8.0 is not required (but is still recommended).

Summary of changes:

• We now statically link OpenSSL 1.1.1 into all Linux release binaries. This should fix issues where users were getting various error messages related to OpenSSL on newer Linux systems. Closes #132 and #126.
• Updated the Linux release binaries to use Qt 5.15.6 and gcc 8.x (gcc 8.1 for the -ub16 binary and gcc 8.4 for the regular Linux binary).
• Updated the Windows release binary to use GCC 11.2.0 and OpenSSL 3.0.1.
• Performance improvement for Merkle tree calculations (as much as 10% speedup).

Pre-compiled binaries for Linux

I have provided two pre-built binaries for Linux:

• Fulcrum-1.8.1-x86_64-linux.tar.gz, which is compiled on an Ubuntu 18.04 system using Docker.
• Fulcrum-1.8.1-arm64-linux.tar.gz, which is compiled on an Ubuntu 18.04 system (for ARM64 bit) using Docker.
• Fulcrum-1.8.1-x86_64-linux-ub16.tar.gz, which is compiled on a stock Ubuntu 16.04 system (using Docker) but with g++ 8.1.0 installed from this ppa source: ppa:jonathonf/gcc-8 & ppa:jonathonf/gcc

All 3 of the above binaries contain jemalloc, libzmq, Qt5Core, Qt5Network (from Qt 5.15.6), and OpenSSL 1.1.1 statically linked. They still require libz2, libstd++, and the right libc version as dynamic libs on your system (but those are usually present if you are on a recent system).

If the first regular -linux binary fails, try the second one (-linux-ub16), which should work on older systems, hopefully.

Pre-compiled binaries for Windows

• Fulcrum-1.8.1-win64.zip - Pre-built, statically linked Windows version.
  • It should "just work" on any Windows 10 or above 64-bit system.
  • Includes is a statically-linked Fulcrum.exe, built with jemalloc, libzmq, Qt 5.15.2, OpenSSL 3.0.1, and gcc 11.2.0.
  • Additionally, FulcrumAdmin.exe is included which is the python script, but made into a onefile .exe using PyInstaller.

Binary builds for macOS coming soon -- Until then you can always build from source!
