Heyo!

I'm starting to develop a game using C w Raylib and AngelScript, installed AngelScript from AUR, following tutorials, I try to compile my prototype, and Error, in include … ‘class’ …, cool, it's for c++, searched a lil, I found this for C: http://www.angelcode.com/angelscript/sdk/docs/manual/doc_addon_clib.html

I tried to compile it using the makefile in clib/projects/gnuc, but it fails with the following output:

g++ -Wall -I/usr/local/include -I../.. -L/usr/local/lib -c -fPIC ../../as_c.cpp -o as_c.o

I'm not gonna lie, I know that it says:

To compile the AngelScript C library, you need to compile the library source files in sdk/angelscript/source together with the source files in sdk/add-on/clib, and link them as a shared dynamic library. In the application that will use the AngelScript C library, you'll include the angelscript_c.h header file, instead of the ordinary angelscript.h header file. After that you can use the library much the same way that it's used in C++.

But I'm not an expert, and tried as it is anyways, I would like someone to point me in the right direction, thanks for your time and have a nice day!

I think the CLib add-on was removed a long time ago because it's not in the latest SDK.

I made progress!

I found here: https://www.angelcode.com/angelscript/resources.html​

at the end, it says:

C interface

I've written a C interface that can be used to integrate AngelScript with other languages than C++, for example C, Delphi, Pascal, etc. As it is not part of the standard SDK I do not keep it updated with every release, but it is quite easy to update for the latest release when needed, so don't hesitate to let me know if you'd like to have it updated.

Download from here

Note: Last updated for 2.31.2 (June 24th, 2017)

Last updated for 2.31.2 :P

Downloaded it and installed the base without problems, error making the clib, somehow a unrecognized option on the compiler ('-Wl'), I removed it and compiles!.

Installed it and now, new problems!:

clang -c -o obj/main.o main.c

I had to:

#define ANGELSCRIPT_DLL_MANUAL_IMPORT

and now it compiles, but I had new problems!, outdated documentation for angelscript_c and no doxygen to generate a new one. I mean, there's no

asEngine_ExecuteString

function on the angelscript_h, so I tried to follow the c++ guide, converting to the c counterparts (ex. "engine->RegisterGlobalFunction" turns out to be “asEngine_RegisterGlobalFunction”). But there's no counterpart for “CScriptBuilder”, since that's from a add-on, and the add-on is a cpp file :S.

I would like some help, thanks by the way ?

It's not that hard to write your own solution, as it boils down to 4 steps:

• asEngine_SetMessageCallback
• asEngine_GetModule
• asModule_AddScriptSection
• asModule_Build

That's basically it, most of your job here is just checking return values and spam user with errors, if there are any.

I'd say for start try to make your own builder function, without looking at scriptbuilder. As you just started, you won't miss that much honestly - preprocessor part is very basic, and metadata can be easily replaced with some config file.

@pibeplay I don't actively maintain the C interface anymore since I really don't have the time for it. However if you identify some changes needed to make it work better, I'd appreciate it if you can send me the updates and I'll have it uploaded to the site.
