Jetpack 4.6 -- error: ‘enable_if_t’ in namespace ‘std’ does not name a template type template <class T, class = std::enable_if_t<!std::is_same<std::decay_t<T>, Callback>::value> about jetsongpio HOT 3 CLOSED

please help me in fixing this issue @pjueon

To compile this library, your compiler must support C++14.

If you're using g++, can you tell me your g++ version?

g++ --version

from jetsongpio.

Or can you add following code before #include <JetsonGPIO> and try to compile again ?

#if (__cplusplus < 201402L) 
// if C++14 is not supported,

// define std::decay_t, std::enable_if_t
namespace std 
{
	template< class T >
	using decay_t = typename decay<T>::type;

	template< bool B, class T = void >
	using enable_if_t = typename enable_if<B,T>::type;
}

#endif

#include <JetsonGPIO>   // include JetsonGPIO header

Edited:
I added this code block to JetsonGPIO.h now.
So you should able to compile after you update your repository.
