[redland-dev] Windows/Cygwin build problems

[Lauri Aalto]

Hi,

building Redland on Cygwin works for me.

These look like end-of-line encoding issues. Some Windows tool of
yours probably converted them to CRLFs while the Cygwin tools still
expect them to be LFs only and complain about the extra CR.

Hard to say about this without the source. The error message looks
like you have a "foo *bar" declaration but have not included the
typedef for foo yet.

Generally, flex and bison generated source builds fine on cygwin.
fix-flex and fix-bison scripts are hacks. They work with the specific
flex/bison versions and input files (raptor/rasqal lexers and parsers)
but do not necessarily work with other flex/bison versions or other
input files.
