> I am trying to compile viewML with my toolchain and ARM based device. 

These errors are all related to the changes between the very old
ViewML source code which used the gcc 2.96 compiler, and
the current toolchains in use today.  ViewML hasn't been
updated in quite some time and is out of date with the
continually-changing C++ "standards".

Regards,

Greg

Is there any other version or branch available that I can use with current versions of toolchain?
