[ANN] Using RubyInline for Optimization

[Joel VanderWerf]

The "average" user might not care about InLine Ruby as much as you do...
I have a lot more to learn before I need InLine and by then it might be
worth DIY to get there.

If an "average" developer uses a library that depends on RubyInline,
then it becomes very important that it be easy to deploy ruby with
RubyInline working out of the box.

You need the MS C compiler.

Well, now I've downloaded and installed Visual C++ 2005 express
edition in order to get that. I also upgraded the RubyInline gem
to the latest, greatest 3.6.0 version.

I set INLINEDIR to
INLINEDIR=C:\ruby\lib\ruby\gems\1.8\gems\RubyInline-3.6.0\demo

To verify that the C-compiler is operational, I commandline-compiled
the following example provided by Microsoft.

#include <iostream>
int main()
{
std::cout << "This is a native C++ program." << std::endl;
return 0;
}

with the line:
cl /EHsc simple.cpp
after running the env var setup script they refer you to.

That all works fine.

So, anyway, here is what RubyInline gives me now ...

Hmmm. Am I getting closer?
BTW. I am using the "One-Click Ruby Installer for Windows" as my Ruby
installation.

Thanks for any help,

So ... no takers on this?

It would be hard to believe that I am the only one
that has (recently) tried to use RubyInline on Windows.

I only got it working after I recompiled ruby from sources using a
combination of cygwin and mingw, and even then I still had to patch
rubyinline to work with mingw.
Are you able to compile extensions using mkmf? If you can do that you
can try comparing the compile commands and adding the missing flags to
rubyinline.

Did you build ruby with this compiler?

BTW. I am using the "One-Click Ruby Installer for Windows" as my Ruby
installation.

... no

You need to use the same compiler for building both Ruby and any
extensions, inline or not.

The simple solution, now that you have a compiler, is to build and
install a new ruby.

 

[Eric Hodel]

If an "average" developer uses a library that depends on
RubyInline, then it becomes very important that it be easy to
deploy ruby with RubyInline working out of the box.

RubyInline has the ability to create a gem that includes the built
library removing the need to install a compiler.

Sigh ... I get the picture.

I guess that means I have to abandon all the fine work done by
Curt Hibbs on the one-click installer and start from scratch.
I am not an ace with C makefiles etc. these days so I sense that
could be a tough road.

Would it be easier to track down the exact C compiler used by
Curt and install that instead?.
