Hi Team, I have a number of projects that I cannot use the online compiler for as it is so old and I have to use offline compilers and cannot share my projects other than via github. Having spent time reviewing all the similar questions on the forums before I posted, I cannot find an answer of WHEN it will support C++11. The key thrust of the logic for having such a very old version of C++ support, seems to be because a vendor (e.g. IAR Systems) only support a very old standard, that the mbed online compiler should therefore be stuck in the past as it has to work with the oldest C++ that any commercial vendor supports. May I suggest that this is hindering the development of ARM based solutions in general and I note that open source communities are supporting C++14 as well as C++11 and older. So, without wishing to start a negative thread of communication, I am requesting that the online mbed compiler quickly introduces C++11 support that if necessary can be managed, perhaps using a flag for the version of C++ compatibility which would be useful moving forward to C++14 and later revisions. Cheers Douglas
