 +===== Status of the Cywgin port ===== 
 + 
 +The Cygwin port of the CWB is **experimental**.  While the source code compiles without error messages and basic CQP queries work well, it is currently not possible to process large corpora (e.g. in the 100M word range). 
 + 
 +The problems we have encountered may be due to limitations in the virtual memory management of Windows and the Cygwin emulation layer manage.  Apparently, a user process is limited to a 2 GB address space in Windows, and Cygwin seems to impose [[http://cygwin.com/cygwin-ug-net/setup-maxmem.html|further restrictions]].  Help from someone with more experience in Windows and Cygwin programming would be highly welcome, so that we can identify the true cause of the problems and try to find a workaround. 
 + 
 +In the long term, we hope to offer a native Windows port of the CWB.  Please join the [[http://devel.sslmit.unibo.it/mailman/listinfo/cwb|CWBdev mailing list]] if you would be interested to work on this port.

 **Important note:** In principle, you can unpack the CWB source code anywhere you like, but //don't put it on a network drive// (we've encountered some weird errors there) and make sure that the directory path //does not contain blanks// (which will happen e.g. if you put the source code on your Desktop). The best solution is probably to keep the source code somewhere in the Cygwin directory tree, e.g. your Cygwin home directory.  **Important note:** In principle, you can unpack the CWB source code anywhere you like, but //don't put it on a network drive// (we've encountered some weird errors there) and make sure that the directory path //does not contain blanks// (which will happen e.g. if you put the source code on your Desktop).

-Then we compile the different components, one at a time. First we clean and check dependencies:+Since the Cygwin port is still experimental, it is probably a good idea to compile each component of the CWB separately. This will make it easier to recognise compilation errors and warnings. First, clean up any old files and check dependencies:
