Subject [jira] Created: (LUCENE-471) gcj ant target doesn't work on windows
Date Fri, 25 Nov 2005 22:16:56 GMT
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


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.
