Code::Blocks 13.12 couldn't be installed on 12.04 using the provided deb packages in the downloads section because of the dependency libfontconfig1 >= 2.9.x.x.
Trying to install it that way breaks the packaging system , but as it comes out I was able to use codeblocks , it appeared in the app menu and I could run it well even though I have libfontconfig 2.8.x , less than the version specified in the dependency of the package.
So , I tried the repository mentioned in that download page (pasgui 's), as it comes out it only has builds for trusty (14.04) .
So , the only way i could do install it is by compiling it myself. (It took a heck of time though
).
Now I still don't have the plugins , though I'll find something.
I created this post to let the developers' and the maintainers know of this issue,so they can look into this. (maybe change libfontconfig1 dependency version.)
