I'm unable to build pandas using git master Cython. I just released pandas 0.7.3 today which has no issues at all with 0.15.1: http://pypi.python.org/pypi/pandas For example: 16:57 ~/code/pandas (master)$ python setup.py build_ext --inplace running build_ext cythoning pandas/src/tseries.pyx to pandas/src/tseries.c Error compiling Cython file: ------------------------------------------------------------ ... self.store = {} ptr = <int32_t**> malloc(self.depth * sizeof(int32_t*)) for i in range(self.depth): ptr[i] = <int32_t*> (<ndarray> label_arrays[i]).data ^ ------------------------------------------------------------ pandas/src/tseries.pyx:107:59: Compiler crash in AnalyseExpressionsTransform ModuleNode.body = StatListNode(tseries.pyx:1:0) StatListNode.stats[23] = StatListNode(tseries.pyx:86:5) StatListNode.stats[0] = CClassDefNode(tseries.pyx:86:5, as_name = u'MultiMap', class_name = u'MultiMap', doc = u'\n Need to come up with a better data structure for multi-level indexing\n ', module_name = u'', visibility = u'private') CClassDefNode.body = StatListNode(tseries.pyx:91:4) StatListNode.stats[1] = StatListNode(tseries.pyx:95:4) StatListNode.stats[0] = DefNode(tseries.pyx:95:4, modifiers = [...]/0, name = u'__init__', num_required_args = 2, py_wrapper_required = True, reqd_kw_flags_cname = '0', used = True) File 'Nodes.py', line 342, in analyse_expressions: StatListNode(tseries.pyx:96:8) File 'Nodes.py', line 342, in analyse_expressions: StatListNode(tseries.pyx:106:8) File 'Nodes.py', line 5903, in analyse_expressions: ForInStatNode(tseries.pyx:106:8) File 'Nodes.py', line 342, in analyse_expressions: StatListNode(tseries.pyx:107:21) File 'Nodes.py', line 4767, in analyse_expressions: SingleAssignmentNode(tseries.pyx:107:21) File 'Nodes.py', line 4872, in analyse_types: SingleAssignmentNode(tseries.pyx:107:21) File 'ExprNodes.py', line 7082, in analyse_types: TypecastNode(tseries.pyx:107:21, result_is_used = True, use_managed_ref = True) File 'ExprNodes.py', line 4274, in analyse_types: AttributeNode(tseries.pyx:107:59, attribute = u'data', initialized_check = True, is_attribute = 1, member = u'data', needs_none_check = True, op = '->', result_is_used = True, use_managed_ref = True) File 'ExprNodes.py', line 4360, in analyse_as_ordinary_attribute: AttributeNode(tseries.pyx:107:59, attribute = u'data', initialized_check = True, is_attribute = 1, member = u'data', needs_none_check = True, op = '->', result_is_used = True, use_managed_ref = True) File 'ExprNodes.py', line 4436, in analyse_attribute: AttributeNode(tseries.pyx:107:59, attribute = u'data', initialized_check = True, is_attribute = 1, member = u'data', needs_none_check = True, op = '->', result_is_used = True, use_managed_ref = True) Compiler crash traceback from this point on: File "/home/wesm/code/repos/cython/Cython/Compiler/ExprNodes.py", line 4436, in analyse_attribute replacement_node = numpy_transform_attribute_node(self) File "/home/wesm/code/repos/cython/Cython/Compiler/NumpySupport.py", line 18, in numpy_transform_attribute_node numpy_pxd_scope = node.obj.entry.type.scope.parent_scope AttributeError: 'TypecastNode' object has no attribute 'entry' building 'pandas._tseries' extension creating build creating build/temp.linux-x86_64-2.7 creating build/temp.linux-x86_64-2.7/pandas creating build/temp.linux-x86_64-2.7/pandas/src gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -O2 -fPIC -I/home/wesm/epd/lib/python2.7/site-packages/numpy/core/include -I/home/wesm/epd/include/python2.7 -c pandas/src/tseries.c -o build/temp.linux-x86_64-2.7/pandas/src/tseries.o pandas/src/tseries.c:1:2: error: #error Do not use this file, it is the result of a failed Cython compilation. error: command 'gcc' failed with exit status 1 ----- I kludged this particular line in the pandas/timeseries branch so it will build on git master Cython, but I was treated to dozens of failures, errors, and finally a segfault in the middle of the test suite. Suffice to say I'm not sure I would advise you to release the library in its current state until all of this is resolved. Happy to help however I can but I'm back to 0.15.1 for now. - Wes _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
