I was looking at Terra as a way to create sort of executable Lua scripts
that I could create on arbitrary Windows machines and then distribute to
other Windows machines as needed. A way to bundle Lua in a nice self
contained manner from, for example, a flash drive. A way to create non
tamperable scripts, so to speak.

If you want to use Terra, you want to interact with C. You’d be calling C
library functions, and compiled Terra libraries are compatible with C.
LLVM is already part of Terra, don’t worry about LLVM. LLVM does not come with
Visual Studio 2013. You just have to have that installed to compile your own
executables or libraries.

LLMV is not a default part of Windows but may well come with Visual
Studio 2013. Have not idea though.
Well I guess that explains things. Bummer. Was hoping Terra was complete
and stand alone.
Thanks for the help.

Hmm, from the “Getting Started” page: "for Windows you need a copy of
Microsoft Visual Studio 2013 installed”
So it does use Windows headers and libs, it seems.

It’s not paths, and LLVM is on Windows. Terra uses LLVM. I don’t think
you
need to install LLVM separately though, did you install Terra?

Path is not it. Just tried a couple.
Still seems that calling saveobj wants to call LLVM, which is not on
Windows. (llvm: program not executable message on saveobj.)

everything
you need installed with Terra itself. Are you sure you got the same
error? I just ran exactly what you sent, and it compiled perfectly.
I will say that you’ll want to use printf to show your output, unless
your
goal is to return the number of arguments + 1.

The example on the first page assumes C is installed. I don't have C

Try using a terra function that takes (argc : int, argv :
&rawstring).
The
main method takes an int, the number of arguments, and an array of
that
many strings.
This is comparable to the C main method.
There is a great example of this on the main page of
http://terralang.org/.

Lots of them:
For example when I type into the REPL
terra addone(a : int)
return a + 1
end
the function is created.
typing print(addone(2)) shows the correct answer.
then typing terralib.saveobj("addone",{main=addone}) gives:
llvm: program not executable
and a stack trace to saveobj
(Other error messages are on the other thread I'm on. All seem to be
about not finding things I'm now thinking would be in a C library or
such.)
Just tried terralib.saveObj(...) in case there's a case sensitivity
issue. Got error message:
[string "stdin"]:1: attempt to call field 'saveObj' (a nil value)
stack traceback:
[string "stdin"]:1: in main chunk

It would help if you could tell us the error.

Hmmm ... just can't get an executable out of Terra. I'm on Windows

not Linux. Default Windows system. Unzipped Terra as per the
documentation. Can get some of the REPL examples to work. As soon
as
I
try terralib.saveobj("MyExecutable",{ main = myMain }) I get an

Do I need to have a C compiler or such installed in order to
create
an
executable?
