I met a problem at the beginning to use QOOXDOO. I am using Windows XP+sp2 with cygwin.
After unzip the sdk.tar ball, I went to /cygdrive/d/qooxdoo/qooxdoo-0.6.3-sdk/frontend/ and typed make source.

But I got the following error message.

—————————————————————————-
* Indexing files…
* Could not read cache from ..\framework\.cache\qx.OO-entry.pcl
make[1]: *** [generate-data-source] Error 1
make[1]: Leaving directory `/cygdrive/d/qooxdoo/qooxdoo-0.6.3-sdk/frontend/
api’
make: *** [source] Error 2

Finally, I checked the source code “filetool.py”.
There are two functions “storeCache” and “readCache”.

cPickle dump a object to a file with the binary protocol, which was opened in text mode.
And load a object from a file, which was opened in text mode.

I made a very small change in them. Then the error was never occur again.

def storeCache(cachePath, data):
try:
cPickle.dump(data, open(cachePath, ‘wb’), 2) #original code: cPickle.dump(data, open(cachePath, ‘w’), 2)
except EOFError or PickleError or PicklingError:
print ” * Could not store cache to %s” % cachePath
sys.exit(1)

def readCache(cachePath):
try:
return cPickle.load(open(cachePath, ‘rb’)) #original code: return cPickle.load(open(cachePath, ‘r’))
except EOFError or PickleError or PicklingError:
print ” * Could not read cache from %s” % cachePath
sys.exit(1)
