Because the anser is only in Google-cache, I just provide it here:
In Ubuntu 10.04 (and probably other newer distributions) LibGDK 2.0 is installed and conflicts with Titanium's internal libraries.
removing ~/.titanium/runtime/linux/1.0.0/libg2.0 or /opt/titanium/runtime/linux/1.0.0/libg2.0 will solve the problem.
To be exact:
This worked. :) Thanks much.
Unfortunately, this advice didn't help me on Ubuntu 12.04 :(
Thanks for adding this.
Hi, I am getting this error but do not see these files specifically. Indeed I am on Ubuntu 10.04.
What I am seeing is that there isn't a libg2.0 exactly, but a many of the unbuilt sources.
~/.titanium/runtime/linux/1.0.0/libgobject (tab complete) I find..
If I enter the commands shown above exactly, it returns that there is no such file or directory. So, I'm not sure if I messed up the install - I've now installed build-essential and think I'm going to delete the .titanium folder and try running the install script again.
This fixed my problems as well, thank you very much. strange enough if I copy the post title and search for it, google marks this page as the #1 result.
