Programming in C, C++ for Mac and Windows?

This would leave me with arr being an Ruby Array representing the vector, right?

right

I see there are rb_each and rb_iterate - should one use ruby iterators to loop through Ruby Arrays in C? Or can one use regular C loops?

definitely rb_ functions as you are manipulating an array of pointers (VALUE objects)

I am confused again now. I got Pellets. And I did what the article said about generating a makefile. But I'm confused to how I compile it.
From what I understand, make is a UNIX command?

Ok, getting close I think, - from the Pelles C Project options I added C:\Ruby\lib\ruby\1.8\i386-mswin32 to the includes path.

But now I get:
Building helloworld.obj. C:\Ruby\lib\ruby\1.8\i386-mswin32\config.h(2): fatal error #1014: #error: MSC version unmatch. *** Error code: 1 *** Done.

Pelles crashed on me - and I swear I heard Homer Simpson's "doh!" as it crashed...

just double click on suext.ppj and it will open in PellesC IDE and then you can Project | Build and you will get a suext.so ready to use

Tried that - but it complained about the project being in the wrong location. Thereafter I got the error I posted in previous post.

thomthom

When I google the error - all I find is people suggesting that one remove
#if _MSC_VER != 1200 #error MSC version unmatch #endif
from config.h.

I take it that you found a way around that?

thomthom

When I open the .ppj files in a text editor I see some minor differences.
What kind of project template do you use?

tbd

added suext6.ppj in SUExt dir on github. it should work now. I use PellesC 5 and something was changed in 6 that made that error.

Thanks to TBD I manage to make my first Hello World SketchUp Ruby Extension running!

Hey Congrats Thom! So when are you moving out of Architecture and into Programmer/Developper full time?

thomthom

when it pays more..?

thomthom

Say that I have a module Foo defined in my ruby script containing a method bar.

How can I reference Foo in C so I can for instance call bar?
symbol = rb_intern("bar"); rb_funcall(??? , symbol, 0);

Would I use VALUE rb_define_module(const char *name) ?

module = rb_define_module("Foo"); symbol = rb_intern("bar"); rb_funcall(module , symbol, 0);

thomthom: yes

when in doubt always try it. faster than posting a question on forum

Just wanted to make sure - some times something appear to work - but later turns out to be very wrong.
