Quickstart How to Build

My main development platforms are AMD Windows (non-Intel Windows (arm) currently unsupported) and Intel FreeBSD.

I rarely use Linux or MacOS or whatever (for compiling), so fixing may be needed.

I support only g++/clang++, no Visual C++ or others, sorry

You need it for ESXi too, even if it doesn't work. Don't be afraid, zpaqfranz knows!
Library dependencies are minimal: libc,libc++,libcxxrt,libm,libgcc_s,libthr

DEFINEs at compile-time: IT IS UP TO YOU NOT TO MIX LOGICAL INCOMPATIBLE DEFINITIONS!

As explained the program is single file, be careful to link the pthread library.
(nothing)                        // Compile for INTEL Windows
-DHWBLAKE3 blake3_windows_gnu.S  // On Win64 enable HW accelerated BLAKE3 (with assembly)
-DHWSHA1                         // On Win64 enable HW SHA1 (-flaghw)
-DHWSHA2                         // Enable HW SHA2 (without assembly code to be linked)

-DSOLARIS                        // Solaris is similar, but not equal, to BSD Unix
-DNOJIT                          // By default zpaqfranz works on Intel CPUs  
                                 // (for simplicity I'll call them Intel, meaning x86-SSE2 and amd64)

-DBIG                            // Turn on BIG ENDIAN at compile time
-DDEBUG	                         // Old 7.15, almost useless. Use -debug switch instead
