_______________________________________________________
Details:
The FDEV_SETUP_STREAM macro defined in stdio.h only compiles for C99 because
it uses designated initializers. The file attached shows a minimal program
that shows the problem, adapted from the documentation here:
http://www.nongnu.org/avr-libc/user-manual/group__avr__stdio.html#stdio_without_malloc
However, when the program is compiled as C++, by giving the file a .cpp
extension, the following errors appear:
$ avr-gcc fdevopenbug.cpp
fdevopenbug.cpp:6:24: sorry, unimplemented: non-trivial designated
initializers not supported
fdevopenbug.cpp:6:24: sorry, unimplemented: non-trivial designated
initializers not supported
fdevopenbug.cpp:6:24: sorry, unimplemented: non-trivial designated
initializers not supported
This bug can be fixed by using a full initialization rather than the
designated one.
