World: r3wp

maybe but doing so on several thousand line parse rules is, well, 
more work than probably trying the R3 as a dll  :-D

You are thinking about scale relative to the wrong number. It's not 
a matter of how many lines the parse rules have, it's a matter of 
how many additions there are in R3 parse, and there aren't that many. 
Make the compiler once, and it will compile quickly. It could even 
do so at runtime.

R3 Host-Kit A100 has been uploaded to www.rebol.com.  This release 
can build CORE or VIEW (with externalized graphics lib.)


However, although the graphics lib is there, the DRAW commands are 
still in the process of conversion (Cyphre will be working on that 
part).


It's also an example (and a fairly simple one to learn from) of how 
to build a host-based extension module, including a few scripts that 
show how to process the module source to embed it in the boot.

Although Cyphre and I have both been able to build it using Mingw, 
other's have not been able to do so, and we're not sure why as of 
yet.


Therefore, we're not quite ready to distribute the host-kit to everyone, 
because we need more testing on it. However, if you want to actually 
test it (windows only), then ask Henrik for the download URL.

The host kit comes with all files necessary to build itself.  In 
theory, all you need to do is type "make" and it will produce R3/View 
(as r3.exe).  Also, make core will produce a core exe, w/o graphics.

why not just post the url ??

more eyeballs is better

The code includes some new host source files, for example to handle 
windowing and the related events.


Although this release comes with the AGG sources needed to do the 
build, note that these sources are pre-GNU versions, so are a bit 
older.


In addition, I suspect Maxim or someone may want to try creating 
an OpenGL version.


Soon, we plan to take a long look at making PAIR! into a float-based 
point, to allow better control with graphics. This somewhat non-trivial 
due to the assumptions in code that PAIR! is integer only with truncation 
for math operations.

are better

Ok by me, but someone will need to collect the comments and issues. 
 You want to do that?

Can we include our own protocols now ?

Sure .. I'll just add it to my Jira tracker

This secrecy is really over the top ...

so this host kit is only buildable under mingw, not VS?

No, I mean someone needs to digest the issues and fixes, and submit 
them back.

Heck, even if no one digests the issues, nothing is lost.

It's not secrecy...

If you don't post the URL, you'll simply not get the issues reported.

The host-kit can be built by any reasonable C and C++ compiler/linker.

k - I was able to build the a96 one - will give this one a go too

I'm fine with posting it.  But, I don't have the bandwidth for the 
backchannel, so we need someone else to handle that.

Thanks.

Any timeline for a Linux libr3.so?

also appreciate the link, Carl

Pretty easy to do, but let's take this one step first.

Do you have an integrated cross-plattform build for the host-kit?

Graham: I got the message on protocols and it's on the list.

If not, someone could write one, if you release a Linux hostkit as 
well. If you do, why not release a single cross-platform package?

Andreas, no, but only because not yet tried that.  Only minor edits 
to the makefile required to build on Linux. If you get that to work, 
then can get you the r3lib to try it. Let me know.

(That's because we don't build view yet for Linux.)

(Only Core)

Yeah, I'd really appreciate if you could send libr3.so to me. I already 
wrote an integrated build for the A96 hostkit.

What exactly do you mean "integrated build" -- you mean makefile?

A single source base which automatically builds correctly for the 
platform the build tool is invoked on.

What have you tried it on?

A96 hostkit on Linux and Win32.

Yes, it basically boils down to an adapted Makefile along with an 
auto-generated header file (or defines) for platform-specific config.

A few things on that...

The makefile is auto-generated and changes with each release. 


Also, there are big variations in make between target platforms (some 
are really horrible.) So, the makefile is kept very "dumb" to allow 
those builds.

So, we will want to get the makefile maker to do the right thing.

Second, the config controls are already part of R3, and are triggered 
by the reb-to.h file.

I used CMake, which is a cross-plattform tool that automatically 
generates "project" files for a variety of targets (such as GNU Make, 
Eclipse project files, Visual Studio project files). It works great 
on Linux, Win32, OSX and is used by several high-profile projects. 
But I'm well aware that third-party tools are most likely no-go for 
REBOL, so I'm fine with all that, and can easily look into it, as 
long as there' s at least a Linux hostkit available.

So, what header files do you find a need to generate above?

I would recommend cmake as well, seems to work well

I can only talk about A96.

What is the input to cmake?

http://203.97.234.193:8080/secure/project/ViewProject.jspa?pid=10020 
... I've added a hostkit tracker to my Jira instance.

BTW, no, I'm fine with supporting as many target formats as possible!

CMake does basically the same thing your "makefile maker" tries do 
to.
