error when no gpu?

[Pinnh]

when make in cpu model errors happen as follow:

/caffe-augmentation/include/caffe/util/device_alternate.hpp:15:36: error: no ‘void caffe::K1_EuclideanLossLayer::Forward_gpu(const std::vector<caffe::Blob>&, const std::vector<caffe::Blob>&)’ member function declared in class ‘caffe::K1_EuclideanLossLayer’
const vector<Blob>& top) { NO_GPU; }
^
/caffe-augmentation/src/caffe/layers/K1_euclidean_loss_layer.cpp:86:1: note: in expansion of macro ‘STUB_GPU’
STUB_GPU(K1_EuclideanLossLayer);
