Linking angelscript into C. Problem when building AS_C_INTERFACE
Author
Hi,
I'm new to angelscript. I've been trying several scripting libraries for the last few days and when I saw angelscript's quick reference I thought I had found my little holy grial.
But now that I'm trying to link it into a C based program I'm encountering problems. I understood from the manual it was possible to link it into C, after some searching I understood the way of doing it was compiling it with: AS_C_INTERFACE;AS_NO_CLASS_METHODS (and ANGELSCRIPT_EXPORT for the lib linking). Well... angelscript doesn't build when using these. The library headers try to use class methods in the building path with class methods disabled.
Could anyone help me here? Does anyone have it linked into a C program?

I actually started on the same thing, never quite finished (for other reasons) but I made it compile. You only need to patch angelscript.h:
While we're on the subject: how would you deal with strings when interfacing with C? AngelScript offers no built-in string type (unless I'm completely oblivious) and the add_ons/scriptstring.(cpp|h) is just a wrapper for std::string.

AngelScript offers no built-in string type (unless I'm completely oblivious) and the add_ons/scriptstring.(cpp|h) is just a wrapper for std::string.

Thanks!
I don't know about the strings, I guess with C callbacks. I'm still in my first steps here. I didn't know of the angelscript add_ons code yesterday when I posted this.
I now think I will create a module in C++ to manage angelscript which will only offer handles to the C program, so the module can use that addons code. Not sure yet, I'm still scratching the surface.

I'll take this feedback and improve the C interface. I'll probably write a separate C header file rather than keeping everything in the principal header file.
As for the string type; You ought to be able to use the asBSTR type that I developed in the early days of AngelScript and that is still supported. You'll find the source code for this in the tests/test_feature/source folder.

For some inexplicable reason I just can't reach your site (Angelcode) for nearly two weeks running. I'm wondering if it is possible to have Angelscript mirrored anywhere else?
It's unexplicable to me too. :( I've alerted the GameDev.net staff that hosts my site, but so far they haven't been able to determine the cause. It seems to be their IIS server that's having some trouble.
