If you want to know what Continuous Integration is, or why it is useful, you could start by reading the article I wrote about that. I manage several open source long-lived Lua projects. I have continuous integration in almost all of them, and it has been of great help. C interface should make integration with c easier. Supposed to improve performance by directly using std::strings and shared pointers instead of requiring raw char. pointers. Lua is pure C and its great for a lot of applications (embedded systems and what not), but when writing c code, integration with C libraries is not so fun IMO. Start - Script: script.lua print('I am using Lua from within C') - End There, told you it was a very basic script! When we embed Lua into C, we will ask Lua to open and run that file. For more examples, see the end of the tutorial. Now for the C code. Create a new text file called and save it as 'embed.c'.

hi
i am having a problem integrating Lua into C++. I found a discussion about it here but it didn't help me. i have installed lua and i can see it in /usr/include and /usr/lib and /usr/bin
i created the same code as the previous descussion

the compile command that i use
gcc -llua lpeg_test.cpp

i get

/tmp/ccsSzCTD.o: In function `main':
lpeg_test.cpp:(.text+0x10): undefined reference to `luaL_newstate()'
lpeg_test.cpp:(.text+0x1d): undefined reference to `luaL_openlibs(lua_State*)'
lpeg_test.cpp:(.text+0x2b): undefined reference to `luaL_loadfile(lua_State*, char const*)'
lpeg_test.cpp:(.text+0x47): undefined reference to `lua_pcall(lua_State*, int, int, int)'
lpeg_test.cpp:(.text+0x5a): undefined reference to `lua_close(lua_State*)'
/tmp/ccsSzCTD.o:(.eh_frame+0x12): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status

can someone tell me what am i doing wrong ??

If you are going to use a C library in C++, you need to compile the headers in C
style. That is done like this:

To compile and built it use: g++ test.cpp -llua You may need to add a -I flag to point to the lua include directories and -L flag to point to your liblua.so library. [In your case, your lua files are in /usr/include and /usr/lib so it is highly unlikely that you will need the -I and -L flags]

How To Embed Lua In C++

Description

Olá… and welcome to our complete Lua scripting course.

This course will teach you everything you need to know about the Lua scripting language.

How To Integrate Lua With C++

We will start from scratch, installing Lua in your platform (Windows, macOS, or Linux), and progress to learn the main aspects of the Lua language. I will use Linux during the videos, but you can easily follow along with any other OS. If by any chance you cannot or do not want to install Lua in your machine, you can simply use the Replit website which allows you to run your Lua scripts inside your web browser.

This course is divided into three main parts:

The first part is where we will cover the basics of the Lua language. We will learn the fundamentals of programming with Lua using variables, expressions, conditional statements, loops, functions, metatables, and other important commands and modules from the Lua language. This part covers Lua from the beginning to an advanced level, and it is a super course even if you never programmed before.
The second part of the course is aimed at programmers that want to learn how to embed Lua within the C programming language. You’ll learn how to embed and expose scripting capabilities to your C code and create a project that controls the movement of a player in C using Lua. If you don’t want or don’t care about integrating Lua with C, you are welcome to skip this section of the course, but this integration with C is one of the most powerful aspects of the Lua language and it is extremely important for professional programmers that want to take their Lua skills beyond the basics.
The third part of the course is a set of short bonus lectures that cover the basics of using Lua with Roblox Studio. Roblox is a popular game engine that uses Lua to script game logic and aspects of the game scene. We will learn how to use everything we learned to understand how Lua is used by Roblox and also understand the basics of the Roblox Studio interface.

This course is a super complete package about one of the world’s favorite scripting languages. You will benefit from it if you are a beginner or if you are a seasoned developer that wants to discover the power of the Lua language.

It will provide you with unlimited Gems and Gold in the game with little to no efforts.I know you are in the right place because you are searching for some working Clash of Clans hack and I can tell you that you just found one and yes – it is working like a charm. Over time we have noticed a lot of searches coming through, people looking for Clash of Clans hack for android or iOS, Clash of Clans cheats on windows mobile. Spend less than 5 minutes of your time and get unlimited Gems and Gold now!

Be aware: This is not a complete course on Roblox. The main focus of this course is the Lua programming language, and the final bonus lectures are a basic overview on how Lua is used by Roblox developers.

Welcome aboard!

Who this course is for:

Beginner that want to learn how to code with Lua
Professional programmers that want to learn how to embed and use Lua with their C applications
Students that want to learn how Lua is used with Roblox Studio

Requirements

Students should know how to work with files, use a text editor, copy and paste files, etc.
Knowledge of the Linux or Windows command-line will help students to make the most of this course
