setDefaultBackend undefined #52

Closed alior101 closed 5 years ago

alior101 commented 5 years ago

Modifying example1 to have a default OpenCL backend fails compilation: 

int main()
{
    //Create a SP that takes in 128 input bits and generates 32 bit representation
    auto gpu = std::make_shared<OpenCLBackend>();
    setDefaultBackend(std::make_shared<OpenCLBackend>());
    SpatialPooler sp({128}, {32});

Weird... Let me have a look. Is the problem re-creatable on Docker?

@alior101 I think I have encountered this problem before and have fixed it. May you pull from master and see if the problem still exists?

alior101 commented 5 years ago

working after merge with master
