@MrBricker, have you found a solution to this?

/home/osmc/pvr.rtl.radiofm/src/RadioReceiver.cpp:707:60: error: invalid initialization of non-const reference of type 'CStdString& {aka CStdStr<char>&}' from an rvalue of type 'CStdString {aka CStdStr<char>}'

                                                            ^

I am running into the same issue when compiling for LibreELEC 8.2.5 (both x86_64 and Raspberry Pi 3 builds) using a host running Linux Mint 18.3 (Ubuntu 16:04 x86_64).
