For Linux:
Normally you can directly use the binraries in bin/linux directory (e.g. bin/linux/x86_64/vtoydump).
These binaries are static built version and should work for most distros.
Also you can build from source for your distro. Of course, gcc must be available before build.
Just run sh build.sh to build vtoydump.
If your OS is x86_64 then the output vtoydump is just for x86_64 architecture, so as for i386 and arm64.

For Windows:
Normally you can directly use the binraries in bin/windows directory (e.g. bin/windows/NT6/64/vtoydump.exe).
Also you can build from source for your distro. Of course, VisualStudio must be installed before build.
Just click the bat file (e.g. build64.bat) to build vtoydump.exe.
