xAODCoreSTLDict Fix, master branch (2021.03.30.)

Attila Krasznahorkay requested to merge akraszna/athena:xAODCoreDictFix-master-20210330 into master

This is a weird one, and a follow-up from !41646 (merged).

It turns out that the formalism introduced by !41646 (merged) makes the build on macOS crash. For some reason genreflex gets very confused about the configuration that's currently in the master branch. 😕

I tried for a while to find an incantation that would

  • generate all the required dictionaries on both macOS and Linux;
  • not crash on either of them.

But I just couldn't. On Linux we just must use the <class pattern="..." /> formalism to access types like __pair_base<string,vector<float> >. (Whose name we should really never hardcode into our dictionaries, as they're super platform specific.) But using <class pattern="..." /> just always crashes with ROOT 6.22/02 on macOS. 😦 So in the end I just decided to @#$% it, and introduce separate XML files for Linux and macOS...

For completeness, this setup results in the following types getting dictionaries on Linux:

class __pair_base<string,vector<float> >
class __pair_base<string,vector<int> >
class __pair_base<string,vector<vector<float> > >
class __pair_base<string,vector<vector<int> > >
class pair<string,vector<float> >
class pair<string,vector<int> >
class pair<string,vector<vector<float> > >
class pair<string,vector<vector<int> > >

And these ones on macOS:

class pair<basic_string<char,char_traits<char>,allocator<char> >,vector<float> >
class pair<basic_string<char,char_traits<char>,allocator<char> >,vector<int> >
class pair<basic_string<char,char_traits<char>,allocator<char> >,vector<vector<float> > >
class pair<basic_string<char,char_traits<char>,allocator<char> >,vector<vector<int> > >
class pair<std::string,std::vector<float> >
class pair<std::string,std::vector<int> >
class pair<std::string,std::vector<std::vector<float> > >
class pair<std::string,std::vector<std::vector<int> > >
class pair<string,vector<float> >
class pair<string,vector<int> >
class pair<string,vector<vector<float> > >
class pair<string,vector<vector<int> > >

Yeah, there is little rhyme or reason to the whole thing... 😕
