CTYPE 0.9.2 porting problems
Hi all, I ported ctypes 0.9.2 to QNX6.3 ... 99.9 % is working but only the unittest test_functions.py makes some problem. Here is the code: p = pointer(c_int(99)) result = f(p) self.failUnlessEqual(result.contents.value, 99) #---> works!! # We need to keep the pointer alive, otherwise the contents change: result = f(pointer(c_int(99))) print result.contents.value self.failIfEqual(result.contents.value, 99) Error message: # python test_functions.py ..99 F. == FAIL: test_pointers (__main__.FunctionTestCase) -- Traceback (most recent call last): File "test_functions.py", line 194, in test_pointers self.failIfEqual(result.contents.value, 99) File "/usr/local/lib/python2.3/unittest.py", line 310, in failIfEqual raise self.failureException, \ AssertionError: 99 == 99 What's the problem here? 99 isn't equal 99 :) -- Ran 16 tests in 0.053s FAILED (failures=1) # # XXX But this not!

Realy ? I have downloaded the lwc distribution and checked it out.
It was a surprise that none of the examples are working.
I'm using SuSE 9.0 with gcc 3.3.1 ...
Is there a working version of lwc ???
