Re: [Kaldi-developers] [Kaldi-users] Kaldi compiles now under VS 2013

[Daniel P. <dp...@gm...>]

To the extent that your patches are simple fixes and minor changes to
the code, I think we could apply them.  Perhaps you could work with
Yenda to get your changes checked?  If you update your git repo to
point to the current code, then a patch should be applicable by the
program "patch" to the svn repo too.
Regarding your build approach, you could send me and Yenda some
details about how you did it, and we could consider whether to support
that.
I don't think it makes sense to try to maintain a parallel
"windows-compatible" version of the scripts, if there are larger
changes required there.  Anyway you depend on cygwin for scripting,
and the set of people who want to run cygwin and build with MSVC is
probably limited enough that I don't think it makes sense for us to
try to support it.

The main problems are 1) pathnames, as shell scripts pass unix-style paths to kaldi programs and 2) binary files on stdin/out, which get promptly corrupted by LF -> CR LF expansion on output unless configured. Most kaldi *bin/ programs already apply the setting, but OpenFST tools do not.
