This is a follow up to my previous question about templates: Unable to use typedef definied in templated structure
When building the following piece of code, the compiler doesn't find the implementation of function, and outputs the the following error.
./test.cpp: In function ‘int main()’:./test.cpp:30:13: error: no matching function for call to ‘function(BUFFER_T<128>::FRAME_DATA)’ 30 | function(buffer.FrameData); | ~~~~~~~~^~~~~~~~~~~~~~~~~~./test.cpp:20:6: note: candidate: ‘template<unsigned int BufferSize> bool function(typename BUFFER_T<BufferSize>::FRAME_DATA&)’ 20 | bool function(typename BUFFER_T<BufferSize>::FRAME_DATA& FrameBufferInput) | ^~~~~~~~./test.cpp:20:6: note: template argument deduction/substitution failed:./test.cpp:30:13: note: couldn’t deduce template parameter ‘BufferSize’ 30 | function(buffer.FrameData); | ~~~~~~~~^~~~~~~~~~~~~~~~~~How can I fix this error?
