Hi there,

I have encountered the following error during the execution of pygccxml. If I launch castXML myself it sucessfully generates the XML file so I guess the issue comes from the parsing:

decls = parser.parse([filename], config)

File "/usr/lib/python2.7/site-packages/pygccxml/parser/init.py", line 51, in parse
declarations = parser.read_files(files, compilation_mode)
File "/usr/lib/python2.7/site-packages/pygccxml/parser/project_reader.py", line 264, in read_files
return self.__parse_file_by_file(files)
File "/usr/lib/python2.7/site-packages/pygccxml/parser/project_reader.py", line 332, in __parse_file_by_file
leaved_classes = self._join_class_hierarchy(answer)
File "/usr/lib/python2.7/site-packages/pygccxml/parser/project_reader.py", line 481, in _join_class_hierarchy
derived_info.related_class)]
KeyError: (('/opt/rh/devtoolset-7/root/usr/include/c++/7/type_traits', 580), ('::', 'std', 'type'))

I'm using clang 8.0, castXML 0.2 botuh compiled with GCC 7.3 on CentOS 7.6.

If I'm generating the xml file myself and then using the parse_xml_file function imported from "parser" I manage to parse the file.

By adding the flag compilation_mode=parser.COMPILATION_MODE.ALL_AT_ONCE to the parser it works as well with pygccxml

I'm trying to parse only one hpp file but it contains lots of template classes and other includes.

I was trying to figure it out the source of the issue but I have not managed it yet. Does somebody have an advice?

Did anyone have any luck solving this one? I am currently experiencing the same error trying to parse 2 C++ headers using cast XML and py++
