caffe installation: gcc error namespace "std" has no member "isnan"

Question

I'm trying to install (py)caffe on ubuntu 17.10

However when I do make all I get the following error:

./include/caffe/common.hpp(84): error: namespace "std" has no member "isnan"

./include/caffe/common.hpp(85): error: namespace "std" has no member "isinf"

2 errors detected in the compilation of "/tmp/tmpxft_00004921_00000000-19_nesterov_solver.compute_61.cpp1.ii".
Makefile:594: recipe for target '.build_release/cuda/src/caffe/solvers/nesterov_solver.o' failed

or when I use cmake instead

/home/thijser/caffe/include/caffe/common.hpp(84): error: namespace "std" has no member "isnan"

/home/thijser/caffe/include/caffe/common.hpp(85): error: namespace "std" has no member "isinf"

2 errors detected in the compilation of "/tmp/tmpxft_00004e32_00000000-7_math_functions.cpp1.ii".
CMake Error at cuda_compile_1_generated_math_functions.cu.o.Release.cmake:282 (message):
  Error generating file
  /home/thijser/caffe/build/src/caffe/CMakeFiles/cuda_compile_1.dir/util/./cuda_compile_1_generated_math_functions.cu.o

Note that I'm not just going for sudo apt-get install caffe as doing so does not also install pycaffe, any solution that also installs pycaffe is also valid. I understand that isnan in std likely comes via boost or that this somehow involves a discrepancy between c++ versions? I'm not much of a c++ expert so I'm not sure how that works, I use gcc4.9 for this as nvcc doesn't like later versions of gcc. I know that caffe works on other people's machines and on a older version of ubuntu I had installed so that suggests it's all a configuration issue.

Anybody know how to fix this?

edit using verbose mode on cmake I was able to find out that it doing the following as it happened

/usr/bin/cmake -E remove /home/thijser/caffe/build/src/caffe/CMakeFiles/cuda_compile_1.dir/util/cuda_compile_1_generated_math_functions.cu.o.depend.tmp /home/thijser/caffe/build/src/caffe/CMakeFiles/cuda_compile_1.dir/util/cuda_compile_1_generated_math_functions.cu.o.NVCC-depend

/home/thijser/caffe/include/caffe/common.hpp(85): error: namespace "std" has no member "isinf"

testing against the following code: https://ideone.com/Yxvt5m

$ gcc -std=c++11 test.cpp which is the same as g++ test.cpp gave me

test.cpp: In function ‘int main()’:
test.cpp:7:15: error: ‘__builtin_isnan’ is not a member of ‘std’
       cout << std::isnan(42.0) << std::isinf(42.0);
               ^
test.cpp:7:15: note: suggested alternative:
<built-in>: note:   ‘__builtin_isnan’
test.cpp:7:35: error: ‘__builtin_isinf_sign’ is not a member of ‘std’
       cout << std::isnan(42.0) << std::isinf(42.0);
                                   ^
test.cpp:7:35: note: suggested alternative:
<built-in>: note:   ‘__builtin_isinf_sign’

suggesting an configuration issue on my machine, however clang++ test.cpp did not give any error suggesting that maybe we could use that to install caffe?

Edit: thanks to @EliahKagan 's suggestions in the askubuntu chat I found that adding in the line CXXFLAGS += g++ -D_GLIBCXX_USE_C99_MATH -std=c++11 to the makefile solves this issue, however it inimitably throws the next error of

thijser@AI-core-Regain:~/caffe/build$ make all

In my case, I also met this error when I built caffe on ubuntu 17.10, but I finally found solution:

Let add the following to:

/usr/include/x86_64-linux-gnu/c++/5/bits/c++config.h

/* #undef _GLIBCXX_USE_C99_MATH */
#define  _GLIBCXX_USE_C99_MATH  1
