-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, A few days ago I compiled wxRuby on Ubuntu 10.04 Lucid Lynx and came over some issues not mentioned at [http://wxruby.rubyforge.org/wiki/wiki.pl?BuildingOnTopOfLinuxDistroPackages](http://wxruby.rubyforge.org/wiki/wiki.pl?BuildingOnTopOfLinuxDistroPackages) First and most importantly, even though I though I had all necessary packages installed, I was presented many errors about ld not finding lgtk-x11-2.0 and other important libs as pango. I figured out that for whatever reason, these files didn’t exist on my Ubuntu installation: /usr/lib/libgtk-x11-2.0.so /usr/lib/libgdk-x11-2.0.so /usr/lib/libatk-1.0.so /usr/lib/libgdk\_pixbuf-2.0.so /usr/lib/libpangoxft-1.0.so /usr/lib/libpangox-1.0.so /usr/lib/libpango-1.0.so Searching for similar named files turned up that I had files ending in “.so.0” in the /usr/lib/ directory. I’m not sure if I was correct in doing so, but I just symlinked them to the needed file names: /usr/lib/libgtk-x11-2.0.so.0 → /usr/lib/libgtk-x11-2.0.so /usr/lib/libgdk-x11-2.0.so.0 → /usr/lib/libgdk-x11-2.0.so /usr/lib/libatk-1.0.so.0 → /usr/lib/libatk-1.0.so /usr/lib/libgdk\_pixbuf-2.0.so.0 → /usr/lib/libgdk\_pixbuf-2.0.so /usr/lib/libpangoxft-1.0.so → /usr/lib/libpangoxft-1.0.so /usr/lib/libpangox-1.0.so.0 → /usr/lib/libpangox-1.0.so /usr/lib/libpango-1.0.so.0 → /usr/lib/libpango-1.0.so After figuering this out, the compilation process complained about missing gl, glu and glut headers which I thought were optional. Maybe I missed some compile option to ommit them and if so I’d appreciate it if someone could enlighten me about that, but installing the freeglut3-dev package did the trick for me. I’m not sure about the StyledTextCtrl’s dependencies–maybe I just have the necessary headers on my system as I tend to install many development packages on compiling problems (not only with wxRuby). Does wxRuby complain on compilation if they’re missing? In short here are my questions: - What’s about that wrongly named shared object files? Is something wrong with my system? - How to instruct rake not to build gl, glu, glut and the StyledTextControl extensions if the necessary development headers are not available for whatever reason? - What are the development headers needed for StyledTextCtrl? Ah, and last but not least, why is the [http://wxruby.rubyforge.org/wiki/wiki.pl?BuildingOnTopOfLinuxDistroPackages](http://wxruby.rubyforge.org/wiki/wiki.pl?BuildingOnTopOfLinuxDistroPackages) page not linked anywhere on the wxRuby homepage? It is only findable by searching for it. There should be a link to it on [http://wxruby.rubyforge.org/wiki/wiki.pl?InstallingFromSource](http://wxruby.rubyforge.org/wiki/wiki.pl?InstallingFromSource) I suggest.

Is something > wrong with my system? First off, doing the symlink is the correct procedure. I found that from Ubuntu 9.04 onwards, they stop putting the symlinks in for the libraries, and therefore when trying to compile, it fails. Symlinking was the correct procedure here to compile. > - How to instruct rake not to build gl, glu, glut and the > StyledTextControl extensions if the necessary development headers are > not available for whatever reason? StyledTextControl by default should be detected on weither it’s installed or compiled or not into the wxWidgets library, if it isn’t compiled, then Rake should detect that, and not attempt to compile StyledTextControl. If you want StyledTextControl, then you need to ensure StyledTextControl is either installed (I believe it should be by default with the Ubuntu repository packages), or going into contrib/stc/ and running make + make install to build and install StyledTextControl. As for gl/glu/glut ignore, I believe that you need to do something like this: EXCLUDED\_CLASSES=GLCanvas rake This basically tells Rake, to ignore GLCanvas. I could be wrong, as I’ve never tried to compile wxRuby without GL, even though I don’t use it personally myself. > - What are the development headers needed for StyledTextCtrl? There shouldn’t be any dependancies you need to install for StyledTextCtrl, as it’s generally compiled into the wxWidgets library, if you build yourself, you would need to go into contrib/stc/ and run make/make install to build the STC code, and wxRuby will automatically detect if it is there, or not, and compile based upon the detection of it being there for you.

Ok I tried unsuccessfully to get wxRuby2.0.1 to work with either ruby1.8 or ruby1.9 and Ubuntu 10.04 by compiling according to the instructions previously mentioned. Does someone have a gem that works? Do I have to remove all traces of wxruby first? What do I need to do to get wxruby working again? Thanks -Philip ---

Do a $ sudo apt-get install libwxgtk2.8-dev freeglut3-dev then set the symlinks I mentioned in my previous post. Afterwards install SWIG 1.3.38 (newer versions won’t work) and ensure the SWIG and Ruby executables are in your PATH. Now unpack wxRuby and $ cd wxruby-2.0.1 $ rake $ strip -x lib/wxruby2.so $ rake gem and you should be done. Works for both 1.8 and for 1.9. But not on Ubuntu Maverick, because a bug was introduced that makes it impossible to compile wxRuby (see another thread of mine a few days ago). Note however that I do not use the Ruby provided by Ubuntu. I think they compile it without the --enable-shared flag wich is required by wxRuby and apart from that the Ruby provided by the Ubuntu packagers is a bit out of date. Therefore I compiled Ruby myself into /opt/rubies/ruby-1.9.2-p0. If you want to that as well, I recommend you to $ sudo apt-get install libssl-dev zlib1g-dev libreadline5-dev libyaml-dev before, otherwise your’re missing some important C extensions (mainly ZLib: Rubygems depends on it).
