Old problem, still no solution: Unknown solver type: SGD

[Peter Neher]

Hi everyone,

I am trying to use Caffe as external library in my C++ project. It compiles fine, but the old "Check failed: registry.count(type) == 1 (0 vs. 1) Unknown solver type: SGD (known types: )" occurs.
I have found discussions about this issue everywhere, but no solution that helped. I am using Ubuntu 16.04, Cmake and I built Caffe with shared libraries. Do I need to define some variable in my projects Cmake to enable registration of the solvers and layers?

Any help is much appreciated!

Peter

It works now when directly using the SGDSolver Class

caffe::Solver<float>* solver = new caffe::SGDSolver<float>(solver_param);

instead of

caffe::shared_ptr<caffe::Solver<float> > solver(caffe::SolverRegistry<float>::CreateSolver(solver_param));

I follow your suggestion and get another error of C2061: syntax error: identifier SGDSolver. 

Any idea to fix it?

I have fixed this error by simply add #include "caffe/sgd_solver.hpp" and got another error
