CouchDB installs fine for everything except execution of views on win7 x64

Question

• Did a fresh install of Apache CouchDB on Windows 7 x64, using setup-couchdb-1.4.0_R16B01.exe

• Can access futon without any problem

• Can programmatically create databases and add documents (including views)

• Get the error pasted below when executing a view (even when executing the simplest default non-edited temporary map-reduce in Futon

  "map": "function(doc){ emit(null, doc); }"

  (in which case the same exact error text is shown in a browser pop-up)

Does this error make sense to anyone? Where should I start my investigation?

Notes:

1. The path c:/cygwin/relax/APACHE~1.0/src/couchdb/ does not exist on my machine...
2. I already tried to uninstall version 1.4.0 and replace it with 1.3.0 and even the older 1.2.0, but the same issue occurs always.

What is the result of running http://localhost:5984/_utils/verify_install.html ?

This error usually happens when people install to a filesystem with ntfs 8.3 filename mangling disabled. Various "tune-up" and performance tools do this for you without understanding the consequences.

Easiest fix is to install to a directory without spaces, e.g. c:\couchdb.

The weird c:\cygwin... lines come up because when CouchDB is built & compiled, error messages are returned with filenames and line numbers present, relative to the build directory, not your future install directory.

Also, the couchdb mailing list is the best place to ask for support (I read it :-).
