Trouble installing a rock (luars232)

[tat...@yahoo.com]

Hello,

I'm not a very experienced programmer in general (I am an EE), but I've taken both a C and a C++ class, and I've spent a lot of time working with Lua over the past few years.

Anyway, I was hoping to get Lua communicating a PCB using RS232 instead of having to rely on NI Labview, and I saw mention of the luars232 module.

I am trying to get luars232 installed (on Windows 7 64 bit).  First it was giving me the "cl is not a recognized command" until I figured out that I had to install Visual Studio to make Luarocks work, and I had to run the luarocks commands using the Visual Studio command prompt.  I did both, and now the cl command is working, but the module fails to install due to this error:

include\librs232/rs232_posix.h(30) : fatal error C1083: Cannot open include file

: 'termios.h': No such file or directory

Anyone know if I am still doing something wrong, or if not, where I can get the correct termios.h file?  I assume it needs to go where ever Visual Studio puts its header files?

Anyway, here is the full text from the command prompt in case it might help:

There are precompiled binaries here:

(For further assistance, you should post on lua-l. In fact, I found the link above searhing in the mailing list archive)

Hi,

another great alternative is to use Lua4Windows
(http://code.google.com/p/luaforwindows/) which is a really nice
all-in-one-install-and-it-works Lua solution (rs232 is part of it).
Of course, Ignacio is right, the luars232 zip is enough for the luars232
question but i think if you want to use Lua on windows there will be
more than the rs232 stuff.
Give it a try, i really like it on Windows (also the shipped version of
the SciTE Editor is nice expanded with lua debugger features). If you
like you can also try dotnet or graphical WXWidgets Stuff with it and
Lua. It just... works...

Bye
Bj�rn
