Problems when compiling library in Arduino IDE

[colincina]

It seems like there are some compilation problems related to the istream and ostream classes. I don't think it is related to my code. I get the following errors just after the compiler says the following:

Compiling library "StandardCplusplus"

This project is dead. You can use my library in its place:

Hi Mike thanks for your work, I wanna get to work "Eigen" for Arduino using your library, is this possible?

The project may be dead but the fix is easy (its in the pull request #20)

You can fix this doing the following edits to remove the unnecessary duplicated default template argument on the nested templates (removal of = char_traits<charT> )

File: istream Line: 343 Before:template <class charT,class traits = char_traits<charT> > class _UCXXEXPORT basic_istream<charT,traits>::sentry {

After: template <class charT,class traits > class _UCXXEXPORT basic_istream<charT,traits>::sentry {

File: ostream Line: 317 Before: template <class charT,class traits = char_traits<charT> > After: template <class charT,class traits>

It helps! Thank you!!!

I was having the same problem, thanks!
