It looks like the definition of the macro DELETE_POINTER is not
expanding to valid C++. Since C++11 (ISO/IEC 14882:2011), similar
functionality is available in the standard, but the keyword is decltype,
not typeof. The typeof keyword was a non-standard GNU extension.
According to the answers in
http://stackoverflow.com/questions/14130774/difference-between-decltype-and-typeof
the "typeof" keyword cannot be directly replaced with "decltype", in
case the expression is a reference. It would seem to me that the macro
should be redefined by using the "auto" keyword, something like this:
auto tmp = ptr;
It looks like all the errors that you posted are due to the same macro
definition.
i think this comes from the, up from gcc-4.9, -std=gnu11 as default C
standard.
Right. Instead of patching the source, you could also try to work around
the issues by specifying -std=gnu++03 or -std=gnu++98.
