i think it's not possible. I clone the geany projet. But during autogen step, it fails with:
``` checking whether g++ supports C++11 features by default... no checking whether g++ supports C++11 features with -std=gnu++11... no checking whether g++ supports C++11 features with -std=gnu++0x... no checking whether g++ supports C++11 features with -std=c++11... no checking whether g++ supports C++11 features with -std=c++0x... no configure: error: *** A compiler with support for C++11 language features is required. ```
I stop here, because i'm not expert and i not understand nothing this!
