How To Build Lua On Windows

Ofttimes Asked Questions

Hither are answers to some frequently asked questions about Lua.
For an introduction to what Lua is, see this summary or learn how to get started with Lua.
For programming questions, see the customs-maintained LuaFaq and too the much longer uFAQ.

1 – Distribution

See the download and go started pages for instructions on how to go source code and binaries for Lua.

1.1 – What do I demand to build Lua?

Lua is implemented in pure ANSI C and compiles unmodified in all known platforms. All you demand to build Lua is an ANSI C compiler (gcc and clang are a pop ones). Lua likewise compiles cleanly as C++.

If you are building Lua in a Unix system (like Linux or Mac OS X), then you probably already have everything yous need and just typing make should do information technology. (You'll merely have to choose a suitable platform.) Otherwise, encounter the next question. In whatsoever case, for full instructions see the README that comes with the distribution. Affiliate 1 of the book Commencement Lua Programming contains detailed instructions for downloading, building, and installing Lua. Here are simple instructions for common platforms:

curl -R -O http://www.lua.org/ftp/lua-v.4.4.tar.gz tar zxf lua-v.4.4.tar.gz cd lua-five.four.iv make all test

If yous don't have coil, effort wget.

If you don't have the time or the inclination to compile Lua yourself, go a binary from LuaBinaries. If you only desire to attempt Lua, try the live demo. Attempt also LuaDist, a multi-platform distribution of Lua that includes batteries.

one.2 – How practice I build Lua in Windows and other systems?

This depends on your compiler. Nearly compilers in these platforms crave that you create "projection" files. You'll need to create projects (or any your compiler uses) for building the library, the interpreter, and the compiler. The sources are all in the src directory. The exact lists of which modules should go into which projection are given in the README. See too BuildingLua in the wiki. Chapter 1 of the book Beginning Lua Programming contains detailed instructions for downloading, building, and installing Lua.

If y'all don't have the time or the inclination to compile Lua yourself, get a binary from LuaBinaries. Try besides LuaDist, a multi-platform distribution of Lua that includes batteries.

1.3 – When is the side by side version due?

Lua is in continuous development but new versions are exceptional.

Lua five.4.4 was released on 26 Jan 2022.

1.4 – What changes will the next version bring?

Lua v.4 was released recently. For a preview of what is coming in the next version, attempt a work version when available.

If you're concerned with incompatibilities, you shouldn't, considering we make every effort to avoid introducing whatsoever incompatibilities. When incompatibilities are unavoidable, previous code is ordinarily supported unmodified, possibly by building Lua with a suitable compilation flag. In any case, the reference manual contains a listing of incompatibilities.

1.5 – Is Lua complimentary software?

Yes, Lua is freely available for any purpose, including commercial purposes, at absolutely no cost, and using information technology requires no paperwork. Read the details in the license page.

i.six – Is Lua compatible with GPL software?

Aye. Lua is distributed under the terms of the very liberal and well-known MIT license, which is uniform with GPL and is canonical past the Open Source Initiative. Read the details in the license page.

1.vii – What practise I phone call software derived from Lua?

Lua is intended to be used in other people's software, including yours. In most cases, Lua is only extended with new functions that adapt Lua to your specific domain. This is exactly what Lua was designed for. When the time comes to distribute your software ii questions may arise: "May I still call the language within my software Lua?" and "May I call information technology something else?".

The answer is the following: If the syntax and the semantics of the language (that is, the parser and the virtual machine) remain the same, and so the language is nevertheless Lua. If you lot simply add together new libraries, or fifty-fifty replace the standard Lua libraries with your own libraries, the linguistic communication is still the same, and you don't need to (and probably shouldn't) give it a completely different name.

If yous take changed the syntax or the semantics of the language, then information technology's probably a minor extension and you'll probably benefit from calling your language a Lua variant, so that you lot tin refer users to existing Lua documentation and community, with the caveats relating to your extension of the language.

Usually, people utilise some name that has Lua as role of it (CGILua, LuaMan, LuaOrb, etc.), and so that information technology is clear that information technology uses Lua only it is not the official Lua distribution. In other words, information technology should be very clear that your software uses Lua (or, more specifically, that the language within your software is Lua), merely also it should be articulate that your software is non Lua.

In whatever case, please give u.s. credit for Lua, according to the license.

If this explanation is still unclear, please contact us.

1.eight – Is there a public revision control repository?

At that place is a public mirror at GitHub of Lua development lawmaking, every bit seen by the Lua team. It contains the total history of all commits, but is mirrored irregularly. Please exercise not send pull requests. Send issues reports and suggestions to the mailing listing. Lua is open up-source software only it is not openly developed. Read this explanation.

If you want to see a preview of what is coming in the next version, yous'll take to wait until a work version becomes available.

1.9 – Do yous accept patches?

We encourage discussions based on tested code solutions for problems and enhancements, but we never incorporate third-political party lawmaking verbatim. We ever try to understand the issue and the proposed solution and then, if we choose to address the consequence, we provide our ain code. All lawmaking in Lua is written past united states of america. See also the previous question.

ii – Information

Consummate data on Lua tin can be found in its home page. You may want to read a summary kickoff, cull an entry point from the site map, or acquire how to become started with Lua.

2.i – Is in that location a mailing list for Lua?

Yes, a friendly and active ane chosen lua-50. Everyone is welcome. Read all about it here.

For discussions in Portuguese, there is Lua BR, the Brazilian version of lua-l.

2.ii – Is there a newsgroup for Lua?

No, just use the mailing listing. If y'all want to read the postings using a web interface, come across the archives at MARC. Y'all may desire also desire to search the archives.

If y'all're looking for a Q&A forum for Lua, endeavor stackoverflow or pt.stackoverflow.

ii.iii – How do I report a bug in Lua?

Beginning, endeavor to make sure that y'all take indeed found a bug. Check whether the problem has been already reported (and probably fixed). Search the athenaeum of the mailing list to see whether someone else has come up across the aforementioned problem and have a fix or an explanation. After that research, if you nevertheless think yous may have found a bug, post a study in the mailing list.

Before reporting a problems, attempt to identify a minimal program that exhibits the issues, besides known as MWE and SSCCE. This makes information technology much easier to reproduce, document, and track downward the bug. As well, read Simon Tatham's essay on How to Report Bugs Effectively.

2.4 – Who uses Lua?

Lua is used in many products and projects around the world, including several well-known games. The total list is too long for united states of america to go on track. See a listing of lists.

2.5 – Are there any books on Lua?

Yes, several. See the complete list here. The book Programming in Lua is a detailed and administrative introduction to all aspects of Lua programming written past Lua'south principal architect. The fourth edition appeared in 2016 and is also available equally an east-book. The showtime edition was published in 2003 and is freely available online. Previous editions are available in several languages. There are several books on Lua by other authors as well.

2.6 – How can I help to support the Lua project?

You can help to support the Lua projection by buying a book published by Lua.org and past making a donation.

Y'all tin can also help to spread the word about Lua by buying Lua products at Zazzle.
