Compiling Mosh (http://mosh.mit.edu/) under Cygwin

mosh-cygwin.md

NOTE: You don't need to compile Mosh on Cygwin yourself anymore; just install the package with Cygwin's setup.exe.

1. Download Cygwin.

2. Run setup.exe and install the following packages in addition to the default ones:

   • make
   • boost
   • libncurses-devel
   • pkg-config
   • perl

3. Download and compile Protocol Buffers (make sure there are no spaces in the working directory when compiling Protocol Buffers, make will fail if there are):

    $ tar zxvf protobuf-2.4.1.tar.gz
    $ cd protobuf-2.4.1
    $ ./configure
    $ make
    $ make install
   

4. Download and compile Mosh:

    $ tar zxvf mosh-1.1.3.tar.gz
    $ cd mosh-1.1.3
    $ ./configure CPPFLAGS="-I/usr/include/ncurses" PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
    $ make
    $ make install
   

5. Install the IO::Pty Perl module:

    $ perl -MCPAN -e shell
    cpan> install IO::Pty
   

6. Rock’n’roll.

Note to future visitors: you don't need to compile Mosh on Cygwin yourself any more; just install the package with Cygwin's setup.exe.

Above instructions is outdated, and the mosh in Cygwin official packages is broken. Instructions to build are here: mobile-shell/mosh#850 (comment)

1. Can't download a .gz. The "Protocol Buffers" link points to a git repository! Since you're supposedly inside cygwin (not a fancy GUI desktop with a full-fledged web browser), you can't access the "download ZIP" option, so you're left with cloning a git repository, so no ".gz", nor useful instructions after that.
   git clone https://github.com/protocolbuffers/protobuf.git --depth=1

./configure
$ make
$ make install

It's all Ancient Mesopotamian dialect for me. I just wanted to install mosh for Windows, not learn to compile (Python, maybe?) under a completely new interface (cygwin, a pseudo Linux that doesn't work exactly as a ny Linux distro) that demands a obnoxiuslt steep learning curve just to use once.
