uint8_t and unsigned char linking error

Question

I'm using template function:

template<typename T> void func(const T& value)
{
    obj->func(value);
}

where obj is object of class:

void my_object::func(int64_t value) { ... }
void my_object::func(uint64_t value) { ... }
void my_object::func(uint32_t value) { ... }
void my_object::func(uint16_t value) { ... }
void my_object::func(uint8_t value) { ... }

The problem is with uint8_t overload of my_object::func() override. Linker complains about unresolved external symbols to overloads, which should have unsigned char parameter.

Should I replace uint8_t overload with unsigned char overload?

Edit: Just now noticed, that linker complains about uint64_t and int64_t too.

I compile on Windows using MSVC++ 2008 Express .

Edit: Apologies, I declared my_object::func(uint8_t value) function (and other), but I didn't defined it.

Answer 1

This is the include file should #include to use the above mentioned types (C99 recommendations)

#include <stdint.h>

Answer 2

我猜uint8_t已被typedef为unsigned char ，因此您会看到它。

Answer 3

Try compiling with

template void my_object::func(int64_t value) { ... }
template void my_object::func(uint64_t value) { ... }
template void my_object::func(uint32_t value) { ... }
template void my_object::func(uint16_t value) { ... }
template void my_object::func(uint8_t value) { ... }

fixed my problem with a similar issues
