[ http://issues.apache.org/jira/browse/LUCENE-471?page=all ]
Michele Bini updated LUCENE-471:
--------------------------------
Attachment: win-mmap.diff
Window implementation of to GCJIndexInput.cc memory mapped i/o
> gcj ant target doesn't work on windows
> --------------------------------------
>
> Key: LUCENE-471
> URL: http://issues.apache.org/jira/browse/LUCENE-471
> Project: Lucene - Java
> Type: Bug
> Components: Other
> Versions: CVS Nightly - Specify date in submission
> Environment: Windows with MinGW (http://www.mingw.org/) and unixutils
> (http://unxutils.sourceforge.net/)
> Reporter: Michele Bini
> Attachments: win-mmap.diff
>
> In order to fix it I made two changes, both really simple.
> First I added to org/apache/lucene/store/GCJIndexInput.cc some code to use
> windows memory-mapped I/O instead than unix mmap().
> Then I had to rearrange the link order in the Makefile in order to avoid
> unresolved symbol errors. Also to build repeatedly I had to instruct make to
> ignore the return code for the mkdir command as on windows it fails if the
> directory already exists.
> I'm attaching two patches corresponding to the changes; please note that with
> the patches applied, the gcj target still works on linux. Both patches apply
> cleanly to the current svn head.
