newlib-nano 64 bit types
Asked by

on 2013-01-13
Hello,
I've just changed from using newlib to newlib-nano and having a problem using printf/scanf with 64-bit integers.
It looks like this is not supported by newlib-nano.
Is there a way to rebuild newlib-nano and enable support for 64-bit integers in printf/scanf?
Thanks in advance.
Matthijs

Hi Matthijs,
Format IO in newlib-nano does not support 64bit integer in source code level, so unfortunately you cannot get it by re-building the library.
For now, the conclusion is only 64bit integer which does not overflow the corresponding 32bit type should be supported in newlib-nano printf/scanf.
Hoping this can help.
Ok, thanks for answering my question. I'll stick to the full newlib library then.
