Ubuntu 18.04 with C++17 and gcc --version gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0 fails about lua-in-cpp HOT 4 CLOSED

Hello and thank you for trying to use my work.
I'm sorry, I realize the mistake I made, when you want to call a C++ function in Lua you have to use the lua API, so the add function in the example should look like this:

int add(lua_State *l)
{
    int n = lua_gettop(l); // get the number of arguments

    if (n != 2) {
        lua_pushliteral(l, "bad number of arguments");
        lua_error(l);
    }

    int a = lua_tointeger(l, 1); // get first argument
    int b = lua_tointeger(l, 2); // get second argument

    std::cout << "[C++] " << a << " + " << b << std::endl;
    lua_pushinteger(l, a + b); // the return value
    return 1; // number of argument returned
}

If you are at the root of the repository then you can compile that way:

make libluaincpp.a
g++ main.cpp -lluaincpp -lua -Isrc
./a.out

Tell me how it goes

from lua-in-cpp.

I updated the repository and provided a way to compile the README example, now you only have to do make test

from lua-in-cpp.

Thank you for the update, but I moved to sol3.

from lua-in-cpp.

Yeah, that's what I was afraid of 😅 The goal when I created this library was to have a simple way to call functions from one language to the other compared to sol3. If you're feeling adventurous you can try this library again 😊
