Version mismatch

[speedpacer]

I've installed Unison on CentOS 6.7 and on Cygwin, both using the git clone method and building from scratch but unison -version responds with 2.49.543 on CentOS and 2.40.102 on Cygwin.

When I try to sync, I receive the error, "Fatal error: Received unexpected header from the server:
expected "Unison 2.40\n" but received "Unison 2.49\n\000\000\000\000\017",
which differs at "Unison 2.49"."

Also, the instructions have changed slightly in Cygwin from what was in INSTALL.win32-cygwin-gnuc. Ocaml has moved from the Interpreters category into their own Ocaml category. In order to compile, I needed ocaml, ocaml-base and ocaml-compiler-libs which are located there, and also flexdll from the Devel category.

Did you build from the same sources on both machines? It seems like the Cygwin installation must be older.

Yes, I didn't try checking out a particular branch or tag, just cloned from the master on both machines. Afterwords, I tried checking out tags/2.40 on my CentOS box but then I got another error while trying to compile, "Fatal error: exception Scanf.Scan_failure("scanf: bad input at char number 4: looking for ':', found '$'")"

Did the master not compile on both machines? That would be the simplest way.

Otherwise the build error is easy to fix — change $Rev$ to $Rev: 600$ near the bottom of mkProjectInfo.ml

My apologies, disregard... I had an old version left over in my path from when I tried installing this on Windows a while ago that I'd forgotten about.
