Failed to build Cafee

[minhtriet]

I ran make -j8 all matcafee and received error src/caffe/layers/softmax_loss_vec_layer.cpp:254:10: error: redefinition of ‘void caffe::SoftmaxWithLossVecLayer<Dtype>::Forward_gpu(const std::vector<caffe::Blob<Dtype>*>&, const std::vector<caffe::Blob<Dtype>*>&)’. Googling does not give any result. Please note that due to my limited GPU, I had to build using only CPU.

Any help is much appreciated.

I have built caffe with CPU too and gave me no problems. Have you tried to re-install Caffe with CUDNN? What GPU do you have?
I saw the same error in the past, but I don't remember how I solved it. Did you check bash_profile/bashrc paths? I think there's something wrong there. Another thing, try to compile by setting
CUSTOM_CXX := clang++ -std=c++11
into your Makefile.config file.

Thanks for your answer.

I checked the bashrc, in fact I have another application that used Caffe, and I make Caffe on that app successfully, using the same Makefile.config that I used to make Caffe in this application.

Enabling GPU build gives me out of memory error, and using CPU build gives me the redefinition error.

I am using Ubuntu 14.04, Graphic card: GeForce GTX 980.

Why are you installing another copy of caffe with the same configuration?
I installed it only once on my machine and I used that for all my applications. Probably this is the problem. Have you tried with the -std=c++11 in the Makeconfig.file?

[minhtriet]

Seems like Deepcut required Caffe to be placed exactly in external/caffe, how did you config it to point to your Caffe installation?
I did try with the -std+c+11 in the Makeconfig.file

I have the same issue. Actually I have successfully installed the main version of BVLC/Caffe with make all pycaffe matcaffe. But the current necessary version (external/caffe) gives me the following error. I set:

CXXFLAGS += -std=c++11
CPU_ONLY := 1
BLAS := mkl

The error log is:

When I comment the following part of src/caffe/layers/softmax_loss_vec_layer.cpp, there is no error :-)

/*
template
void SoftmaxWithLossVecLayer::Forward_gpu(const vector<Blob>& bottom,
const vector<Blob>& top)
{
//LOG(FATAL) << "Cannot use GPU in CPU-only Caffe: check mode.";
Forward_cpu(bottom, top);
}

template
void SoftmaxWithLossVecLayer::Backward_gpu(const vector<Blob>& top,
const vector& propagate_down,
const vector<Blob>& bottom)
{
//LOG(FATAL) << "Cannot use GPU in CPU-only Caffe: check mode.";
Backward_cpu(top, propagate_down, bottom);
}
*/

And it leads to your issue, somehow... Namely, it is the error in syncedmem.cpp.

Hey, I updated the deepcut-cnn repo with the fix CPU-only build, and tested it. So closing this one.
