I have a problem of substitution failure, and answers of some similar questions do not help me.
Here is the main part:
template<int dim, int loop>
class Partition{
// ...
public:
// ...
template<int r, int c> using matrix = int[r][c];
template<int r, int c> readPattern(const matrix<r,c> &pattern)
{
// ...
}
// ...
};
And I call this template function like:
// ...
const int DENOISE_UR[3][4] = {/*...*/};
Partition partition;
partition.readPattern(DENOISE_UR);
// ...
When using clang++(linux) to compile, it resulted in the following compiling error:
error: no matching function for call to 'readPattern'
note: candidate template ignored: substitution failure[ with r = 3, c = 4 ]
template<int r, int c> void readPattern(const matrix<r,c> &pattern)
Why?
What's weird is that the codes above did compile and work on Visual Studio 2013.
