[Kaldi-users] Possible IO problems when reading FSTs under Windows (VS2010)

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

Hi,

There may be some possible IO problems when reading Fsts with the below code:

std::ifstream is(fst_in_filename.c_str());
VectorFst<StdArc>::Read(is, fst::FstReadOptions((std::string)fst_in_filename));

On the Kaldi commands I tried under Windows + VS2010, I had to add the
binary flag to the ifstream constructor to be able to successfully
read in an FST.
std::ifstream is(fst_in_filename.c_str(), std::ifstream::binary);
I think the cause is the different ways Windows and Unix like systems
handle the newline constants when the std::ifstream::binary option is
not specified.


I'm using OpenFst 1.2.7 compiled as DLL which may be causing the
problem just for me. However, the 1.2.7 of the Windows port should
speed up the builds quite a lot.

Thanks for the bug-report; I have changed this to binary-mode I/O as you
suggested (8 occurrences).  Do svn update and it should hopefully work.
