Error 127 in compile softmax_layer

[Antonio Paes]

Hi guys, I`m new in caffe, and when i use the command make all in ubuntu 14.04 i have this error:

make: /usr/local/cuda/bin/nvcc: Command not found

make: *** [.build_release/cuda/src/caffe/layers/softmax_loss_layer.o] Error 127

any help?

Thanks

Hi Antonio,

The message: "/usr/local/cuda/bin/nvcc: Command not found" is telling you that make tried to run the nvidia cuda compiler, which it thought was going to be an executable called nvcc located at /usr/local/cuda/bin, but it wasn't there.

So most likely there's something with your installation of prerequisites, namely cuda 7.0, as described here: http://caffe.berkeleyvision.org/installation.html. Beyond that it's hard to say more without more to go on.

Thanks Jim, resolved this problem, but appear other see you can help me:

 CXX/LD -o .build_release/tools/caffe.bin

.build_release/lib/libcaffe.so: undefined reference to `cv::imencode(cv::String const&, cv::_InputArray const&, std::vector<unsigned char, std::allocator<unsigned char> >&, std::vector<int, std::allocator<int> > const&)'

.build_release/lib/libcaffe.so: undefined reference to `cv::imdecode(cv::_InputArray const&, int)'

collect2: error: ld returned 1 exit status

make: *** [.build_release/tools/caffe.bin] Error 1

I try add opencv_imgcodecs in makefile but the error continue, any sugestion?

Hi Antonio,
Hmmm.. all that's obvious to me at the moment from that is that there's a linker error trying to link to OpenCV. So maybe OpenCV library is not installed? It's one of the dependencies in the caffe installation instructions.

Hi Jim,

already install opencv, i'm use my laptop have a Nvidia GeForce GT 525 M, but I think which this is not a problem or this is? rsrsrsr

Thanks.

Hi Antonio,
The error you showed is a linker error where it's trying to link to opencv. Can't tell why you're getting it. If you are using caffe's Makefile to build, you could try the CMake build instead and see if it works. And vice-versa. Or you could make VERBOSE=1 and look at the linker arguments and see if the library libopencv* is really where the linker is trying to find it.

As far as your GPU, I think this link shows GeForce GT520M is supported by CUDA:

Hope that helps,

Thanks Jim, but I install caffe in server with linux arch, just ran a script that installed all the dependencies.

but thanks for your help.
