Building Ruby extension on Win32

Post by alexg »

Hi,

Just wondering if anyone had successfully built the Ruby extension under Win32. I've been using Chipmunk on OSX and am really impressed, but having a Win32 version would be a great help as well.

I'm using the One-Click installer for Ruby and have tried compiling under MinGW and MSVS8. Using MinGW I run into problems with the Makefile generated - since Ruby generates an nmake compatible makefile which the MinGW make (gnu make) cannot understand. I managed to compile each file by hand using gcc, but ran out of luck at the linking stage. I can give the errors I got here if needed.

Under MSVS8 the Makefile parses fine but CL.exe complains at compilation (this is using the version I downloaded from slembke's last post in the other Win32 build thread):

http://www.slembcke.net/forums/viewtopi ... a&start=10

I've edited the Makefile to make CL compile as C++ rather than C, which gives less errors but maybe isn't the right way forward. Here is the nmake/CL output:

Stop.
My experience with building on Windows is very slim so I'm going to keep playing around, but if anyone has already done this and has any pointers I'd be very grateful. Even just a pointer as to which way (MinGW or MSVS) is likely to be easier would be appreciated.

OK, here's my effort under MinGW. It complains about WinMain@16 missing, which makes me think I'm missing something basic:

I was missing something basic - not specifying I wanted a shared library. Now with shared enabled I get a new error:

Code: Select all

$ gcc *.c -o chipmunk.so -g -O2 -Le:/ruby/lib -Ie:/ruby/lib/ruby/1.8/i386-mswin32 -std=gnu99 -lmsvcrt-ruby18 -shared

Sounds like the Shattered Ruby guy was able to do it. You might want to PM him perhaps.

Thanks. Their .so seems to work fine with the One-Click installer so I'm on my way. :)

Ack!

Sorry to bother anyone here, but ... the ShatteredRuby people apparently forgot to pay their DNS, and nothing they host, including the .so, is available!

Is there anyone who downloaded and has the .so? I'd love to be able to get (even a dated) version of it to play around with. If anyone has it ... err, they could always send it to me by email; check my profile.

I have nothing to offer in return other than naming rights for potential future offspring.
