Why Bison doesn't work properly in Windows (doesn't generate output file)?

Bison o开发者_开发百科n windows does not produce an output file.

This is the error message I get.

m4_define([b4_percent_define(lr.keep_unreachable_states)],
[[false]])

m4_define([b4_rhs_min],
[[-1]])

m4_define([b4_pact_min],
[[-5]])

m4_define([b4_conflicting_rules],
[[     0]])

I have solved this question myself, this is for others.

It seems Bison doesn't correctly handles paths contaning space. Move Bison (GnuWin32) folder to a folder without blanks in it's path.
