[Tutorial] SketchUp Ruby C Extension
-
Just wanted to thank Thomas and everyone else for the contributions in this thread. I tried to get Thomas' Hello World extension working and had no problems at all, thanks to his clear documentation.
My next experiment will be to incorporate SketchUp SDK calls into the Ruby Extension. Has anyone done this? Is it relatively straightforward? Any 'gotchas' that you could warn me about? Thanks
-
Problems already...
I have the SDK .h files installed in the same folder as 'SX_HelloWorld.c'. I'm not sure what to do with the binary files provided with the SDK.I tried to include just one header <slapi/model/model.h> file from the SDK and this was the result.
Feeling clueless...

We're actually working on a Hello World example for Visual Studio and Xcode for compiling Ruby C/C++ Extensions for SketchUp. We can expand that (create a work or extra branch) with SLAPI configured as well.
By the way can you post a Gist of your code? You got some syntax errors there that appear to not be related to linking to the correct headers.

Interesting, I was just now doing some research into 'extconf.rb' and I'm starting to think my problem is related to not configuring the location of the .lib and .h files inside of 'extconf.rb' using the 'dir_config' and 'have_library' commands.
BTW, the only difference between my code and your 'hello world' code on bitbucket is that I #included one the SLAPI .h files at the top.
I had assumed (or hoped) that it would be properly linked since I put the files in the same location as the .c file that I was trying to compile.
It goes without saying that I am a complete noob at this.

Hi Dale
I looked into this and found that you cannot use Visual Studio's nmake for this as it's C89 - and the SLAPI is written in C99.
It would work if you install the DevKit at Ruby Windows Installer - though I'm still working out some minor quirks. We're preparing some Hello World examples to get started with Ruby C Extensions. Can you hang in there a little bit more?

No problem. Thanks for looking into this. I am excited to see the new examples...

Good news is that I got the SLAPI example compiling under OSX. I need to test on Windows and clean up the extconf.rb file a little.

Cool!

It will be very good indeed to have those examples easy to compile and ready to expand.

Hello All,
I am just starting on C extensions for SU and have a quick question. I have been successful following Thom's hello world example on bit bucket. My first question is are there any known IDE solutions to compile from? I don't relish the idea of writing code in notepad++ or other, then compiling from command line, then loading into SU and hoping it works.
Is this the way this is being done now or have I missed something?
In any event, THANK you all for the hard work you have put into this so far, if this is the best known solution, I will follow it.BTW, working within Win7(64)

We are setting up a C++ Hello World example for Visual Studio and Xcode. That will give you better environments to work and debug in.

Thanks Thomas, I offer to do testing if you need it. Otherwise I will keep my eye on this.
