I try to run QtCreator on my raspberry pi2 but without much success. Since the botan package was updated from 1.10 to 1.11, QtCreator cannot load plugins anymore. For example, the libProjectExplorer fails with:
Cannot load library /usr/lib/qtcreator/plugins/libProjectExplorer.so: (libbotan-1.10.so.0: cannot open shared object file: No such file or directory)
Because libbotan 1.11 is not ABI compatible to 1.10 a symlink doesn't help here. QtCreator and/or its plugins must be rebuilt againt libbotan 1.11, I think.
