Hi,
I want to install homegear on a raspberry pi armv6h. Therefore I have downloaded the package from AUR and modified the PKBUILD to support armv6h.
During the build I recevie errors that
error: ‘function’ in namespace ‘std’ does not name a template type
or
error: ‘std::function’ has not been declared
I don’t know whats wrong here because -std=c++11 is set ?!?
