[Rubycocoa-talk] Problem compiling

[Maarten E. <ma...@ir...>]

I'm trying to compile rubycocoa on a intel mac, but the build process
exits with an error when it reaches WebKit. The error message follows
below:

Generating BridgeSupport metadata for: WebKit ...
./gen_bridge_metadata.rb:1841:in `generate_precompiled_header': Can't

command was: gcc -c -x objective-c-header /tmp/src-0-14642.h -o

Any idea what may cause this. For the record: I'm running OS X 10.4.9,
with Safari 3 beta installed (different webkit?). I use ruby 1.8.6
from MacPorts. I also compiled rubycocoa on a PPC machine with 10.4.10
and Safari 3 beta installed.

Thanks and regards,
