I'm new to Lua, and need to know how to install it on Windows?
I've tried and am unable to run the sample. When I try to compile it 100% success is shown, but when I click the run button it shows this error:
Can't find moai executable in any of the folders in PATH or MOAI_BIN:
C:\Program Files\moai, D:\Program Files\moai, C:\Program Files (x86)\moai, D:\Program Files (x86)\moai, C:\WINDOWS\system32, C:\WINDOWS, C:\WINDOWS\System32\Wbem, C:\moai-sdk\bin\win32\moai.exe, C:\moai-sdk/bin
If anyone can help me on how to install Lua, thanks.
Lua does not have a certified IDE or compiler to come with it. You usually run lua code from a lua command line / lua file which will handle the tasks you are attempting to create.
Downloading
Lua has a website where you can download their tools which will allow you to write and execute lua code: https://www.lua.org/download.html
Using lua console
After you download the file, put it in a file location anywhere on your computer, in order execute lua code; the first method is to open the lua console and simply type out your command: https://prnt.sc/ibw97h
Another method you can use, is make a .txt or .lua file, write your code in that, then you can drag and drop the file onto the lua console to execute it: https://prnt.sc/ibwa2f
Installing lua system wide
Add lua in the environment variables by adding the path from where it's installed. After doing this you can open PowerShell and enter lua53.exe to open lua.
Additional details
Although these is what lua directly offers, there are other third party alternatives of compiling and executing lua code. Examples of these can be found if you search for them.
I assume that you are trying to use Moai SDK to develop games.
I think this article may helps.

I'm trying to install Clozure CL using their guide, and it wants me to add the files ccl and ccl64 to my path, but they have no file extension and Windows doesn't know how to run them.
I eventually looked in the file and it was headed by #!/bin/sh. As far as I know, I would need external software to get these files to run.
I want to know if there is some other workaround for setting up Clozure CL more easily, and if there isn't, what would I need to be able to run these files directly from the command line?
It appears that all the scripts do is run the file wx86cl64.exe in the main ccl directory as long as you're on Windows. So, all one needs to do is add the ccl directory to their path to achieve success.
This answer suggests this library to use web sockets for lua.
The installation guide of the library contains three strings:
$ git clone git://github.com/lipp/lua-websockets.git
$ cd lua-websockets
$ luarocks make rockspecs/lua-websockets-scm-1.rockspec
I don't know what results of the last command should be and how to proceed from executing it to compiling examples. But on my PC it only produces error message
'"C:\Program Files (x86)\LuaRocks\\lua5.1.exe"' is not recognized as
internal or external command, operable program or batch file
in visual studio 2015 developer console.
In regular console it just complains that cl is not recognized
I want to know not only ways of fixing the error, but all actions needed to start communicating with websockets from a lua script on windows with this library or another one.
The script will be run in vm provided by a third party app. I can require external modules from it. I installed luarocks from developer console. There are no other installed lua frameworks/compilers. The system is windows 8.
If you need to run this as the client, then you only need three pieces: lua interpreter, luasocket library, and the lua-websockets module you referenced. The module has other dependencies (luabitop and copas), but those are optional if you just want to try simple sync calls using luasocket. You can compile luasocket libraries yourself (that's what luarocks probably attempted for you to do, but you can also do it from the command line) or find already compiled libraries; for example, see this discussion for details.
Is it possible to create Windows executable files for Python and C/C++ code within the Eclipse workbench? If yes, then how can this be done?
This is how I create .exe files from eclipse, in windows. Is not within the eclipse workbench but it might help you. To avoid problems, I would recommend to download everything for 32 bit even if you use 64 bit computer.
Install python 2.6
Install Eclipse
Install py2exe
In eclipse go to Help > Install new software and install pydev plugin from http://pydev.org/updates/
In windows preferences point the python interpreter to the location of your python.exe in your computer (C:/Python26)
you might need to add py2exe to the libraries
create a python module called setup.py with a code similar to this one:
from distutils.core import setup
import py2exe
setup(windows=['H:/yourworkspace/YourPythonProject/src/yourprogram.py'])
open windows console and type
python H:/yourworkspace/YourPythonProject/src/setup.py py2exe
this will create a .exe located in C:/Python26/dist folder. It should work if you double click it but you cannot take it to a computer without python or any of the libraries that you´ve used. To do that, you can use Inno Setup.
It's very easy to use, basically it will ask for the location of the .exe, the dlls and folders that you want to add (I don't know about this so I add most of the things inside my C:/Python26/dist and it works). Inno setup will create an script and generate a .exe that you can install in any computer. You might need to edit the [Icons] part of the script, I had problems with that before to add an icon to the application.
That should hopefully work,
good luck.
Not sure I understand what you're asking as you're mixing Python/C++ in your question...
If you want to embed Python in some library, Google for 'embed python in c++'
If you just want to package Python to run Python code with extension modules, search for py2exe or cx-Freeze (personally, I like cx-Freeze better).
I don't think any of this is PyDev/Eclipse dependent (this should be IDE agnostic).
In addition to Fabio's answer:
In terms of C/C++, if you compile it on windows, eclipse does create yourprog.exe file automaticaly in order to be executed (in case if you have your main function written in C/C++). Look for your executable in bin folder of your project.
In terms of compiler: I use Cygwin. It simulates Linux environment. It contains (not by default though) g++ compiler, which, because of cygwin, compiles it in binary that can be launched in Windows (i.e. .exe file). I am not sure exactly about whether Linux binary is then converted to Windows binary or it is directly compiled for windows, but I know that this .exe file alone works if you run it.
Let me know if you need help installing Cygwin.
I have the .proto file used in the open-source Android API (http://code.google.com/p/android-market-api/), and am having some trouble compiling the file to generate the .py.
I'm trying to follow the instructions here, https://developers.google.com/protocol-buffers/docs/pythontutorial , and am on the steps that are under the header "Compiling Your Protocol Buffers".
I've downloaded the compiler, protoc.exe. The readme says "To install, simply place this binary somewhere in your PATH," which I'm not understanding. I'm messed around with it for a while now, but can't think of how to proceed.
I'm quite the novice programmer, so please tell me if something isn't clear, or if I'm having some sort of fundamental misunderstanding... about anything. I'm on Windows 7 by the way.
Thanks!
if protoc.exe is not in the same directory you're calling it from, you need to add it to your PATH environment variable to be accessible from the calling directory when you're in the shell. open up a command shell and execute:
set PATH=%PATH%c:\directory\to\proto\executable;
then change directories over to where your source code is and execute the compilation line as instructed from the google page.
I had the same problem because it is not written that clear in the README.txt. What they mean is to:
1. take the protoc.exe and put it in the same folder with the other files of your project.
2. open the cmd to that directory and run: protoc --cpp_out=. myfile.proto
=> This will create the 2 new files in the folder with the files of your project, and then you can add them normally to your program.
This helped me: http://www.scriptol.com/programming/protocol-buffers-tutorial.php
This is for c++, but I guess it will be something similar for python; I guess you just have to change the command you are using in the cmd :)
I've got some perl source code here, how do I build it on Windows, to get a windows binary that I can work with?
Usage of external tools normally comes with compatibility issues, random errors etc. You are better off using the inbuilt perl 'pp' tool. Install PAR::Packer (which includes the pp tool) module and then read the manual for it...
It allows you to pack your perl scripts to executables, and has options as what modules and dependencies to include, I've used it on winXP and win7 and never had an issue with any executabe produced.

I've found Cava Packager to be just what I needed.

How to compile Perl scripts into EXEs
Download ActivePerl 5.10 for Windows.
Install it.
Restart your PC.
Download Cava Packager
Install it.
Open it.
Make a new project choosing a blank folder.
Scripts > Add..
Choose your .PL script file
Perl library > [...]
Choose "C:\Perl\bin\perl510.dll"
Add
Choose "C:\Perl\lib\"
Save
Build
You could use the Perl Development Kit from ActiveState to "compile" your script to a .exe file. I used it to create binaries of MRTG and a couple tools more to be deployed on windows servers running as a service. There used to be another product (from IndigoStar or something) called perl2exe I think to get the same result.
Just a note that Cava Packager also supports creating executables from Perl code on Linux and Mac OS X in addition to the original Windows version.
