After updating GCC to version 11.1.0 (from previously using GCC 9), angelscript fails to compile on the latest WIP because of as_symboltable.h:89

Is there any solution to this? Thanks in advance! Been using AS for the past few weeks and it's amazing

Editing a large post seems to be a bit buggy so I'll just post a follow-up here

After a bit of research, I find out that as of GCC 11 you will get a compiler error if you specify the template parameter type on a class constructor with already defined templates. (which wasn't even required regardless of GCC version) See https://codereview.qt-project.org/c/qt/qtbase/+/339417

Removing both the template parameters made the code compilable

asCSymbolTableIterator(asCSymbolTable<T> *table);

As someone who tried many solutions (python, lua, squirrel, angelscript), here my comments.

For me it was not clear how Angelscript had to wrap my objects. I recall having some kind of intrusive reference count, but could not get it. What got most in the way for me was, actually, that Angelscript is statically typed.

I really think that for my scripting purposes (at least) it is better to have a dynamic language. For a static one I already have C++ after all. Angelscript advantage seemed to be that it had been tried in lots of platforms and is similar to C++ (from a C++ POV).

I also tried lua + bindings, it is nice, but lua looks so irregular to me compared to other programming languages (indexing at 1, no classes at all by default, etc.) It is brief though and resonably easy to bind. I did not try it in mobile yet so I cannot speak for this part.

As for python, I just cannot use it for all platforms easily (mobile for example).

Squirrel: tried and it looked nice, but at the end I left it bc doing bindings through its c++ wrapper through sqrat.

At the end I went for Chaiscript and did not move from there since then: dynamically typed, similar to javascript and good integration with C++, very good indeed and its strongest point for my needs. Slow to compile though.
