Thanks, that completely clears things up for me. I likely won't have VS
on any of the machines I could be parked at.

Just to clear some things up. Terra requires the visual studio
compiler for linking (creating of executables, and dlls) but not for
compiling (create object files, or llvm output). Generally even with
LLVM on windows, it is using the underlying linking tools from the VS
compiler to work.

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.

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.)

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.

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

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
error.
Do I need to have a C

installed in order to
create
an
executable?
