Cannot make the caffe-0.999

[tomoc]

Hi. I can't installed caffe-0.999. When I run make, I get the below error.

make: /usr/local/rcnn/R2012a/bin/mexext: Command was not found /usr/local/cuda-7.0/bin/nvcc -ccbin=/usr/bin/g++ -Xcompiler -fPIC -DNDEBUG -O2 -I/usr/include/python2.7 -I/usr/lib/python2.7/dist-packages/numpy/core/include -I/usr/local/include -Ibuild/src -I./src -I./include -I/usr/local/cuda-7.0/include -gencode arch=compute_20,code=sm_20 -gencode arch=compute_20,code=sm_21 -gencode arch=compute_30,code=sm_30 -gencode arch=compute_35,code=sm_35 -gencode arch=compute_50,code=sm_50 -gencode arch=compute_50,code=compute_50 -c src/caffe/util/math_functions.cu -o build/src/caffe/util/math_functions.cuo src/caffe/util/math_functions.cu(140): error: calling a host function("std::signbit ") from a global function("caffe::sgnbit_kernel ") is not allowed

I use ubuntu 14.04. Unable to track what is the problem. Please help.

Thanks.

Hi tomoc,

try with another version of CUDA, for example the 5.5 version.

@ivanDonadello I tryed it. but I got same error... I have no idea.Please help.

Thanks.

Hi tomoc,

You can fix this error by the following steps: 1.comment line 224 in ./include/caffe/util/math_functions.hpp:

//using std::signbit;

2.make a minor change in the next line:

DEFINE_CAFFE_CPU_UNARY_FUNC(sgnbit, y[i] = signbit(x[i]));

to

DEFINE_CAFFE_CPU_UNARY_FUNC(sgnbit, y[i] = std::signbit(x[i]));

3.all done. make it now make clean&&make all -j8

@nhlijiaming Thanks! I have successfully run the "make all" and "make test"! But, when I run "make runtest", it outputs error like below.

I tried to error handling,But it outputs same error.. Do you have any solutions?

[nhlijiaming]

no CUDA-capable device is detected You may need a nvidia video card or run it in CPU_ONLY mode.

[tomoc]

@nhlijiaming Because I don't have GPU,I have already run it in CPU_ONLY mode. I have no idea.

[Aky97567]

@nhlijiaming How can i ensure that caffe-0.999 runs in CPU mode?

[tingtinglu]

@nhlijiaming I also want to run caffe 0.999 in CPU mode, how can I do this?Thanks !

@Aky97567 @tingtinglu Add CPU_ONLY := 1 in your Makefile.config, hopefully it will help.
