[Kde-bindings] Re: Notes on building on Mac OS X

[Ben Skelton]

Thanks Arno, I've done a clean build of smokeqt and it builds fine. 


In building qtruby I ran into a few problems:

1.  libqtruby4shared.dylib, rubyqtwebkit, qtscript, qttest, rubyphonon, rubyqwt, qtruby4

needed to apply -DHAVE_STRUCT_TIMESPEC -DHAVE_STRUCT_TIMEZONE pretty much everywhere

2. QDeclarative module

cmake did not include the libQtDeclarative.dylib in the call to the linker. All the smokeqt libraries were there, but the make complained that it could not find qdeclarative symbols.


Once those are done qtruby builds!

qtruby is installed on my machine at /Users/benskelton/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/. There are two files in that directory 'Qt.rb' and 'Qt4.rb'. Both of these are require calls to the real qtruby.rb. This is installed on my machine in /Users/benskelton/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/Qt. I needed to change both Qt.rb and Qt4.rb from

> require 'qtruby4'

to

> require 'Qt/qtruby4'

then in irb...

which looks like something is wrong, then...

where I was hoping to see a whole bunch of methods that the hello object responds to.

Any ideas?

cheers,
