nvcc compiled program seems to be confusing math.h and cmath.h namespaces

Question

I'm compiling a CUDA program, which seems confused (Or, perhaps I'm confused) about the namespaces used by cmath and math. When I run make, I get the following output:

innovationcommons@IC-VR1:~/PackageDownloads/warp-ctc/build$ make VERBOSE=1
/usr/bin/cmake -H/home/innovationcommons/PackageDownloads/warp-ctc -B/home/innovationcommons/PackageDownloads/warp-ctc/build --check-build-system CMakeFiles/Makefile.cmake 0
Re-run cmake file: Makefile older than: CMakeFiles/test_gpu.dir/tests/test_gpu_generated_test_gpu.cu.o.depend
-- cuda found TRUE
CMake Warning at CMakeLists.txt:48 (FIND_PACKAGE):
  By not providing "FindTorch.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Torch", but
  CMake did not find one.

  Could not find a package configuration file provided by "Torch" with any of
  the following names:

    TorchConfig.cmake
    torch-config.cmake

  Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set
  "Torch_DIR" to a directory containing one of the above files.  If "Torch"
  provides a separate development package or SDK, be sure it has been
  installed.

The errors I get are that isinf and isnan don't belong to the std namespace. My understanding is that this is true if math.h is being imported, but not if cmath.h is being imported. However, I can see in the last compile line that std=c++11, and when I check test_gpu.cu, I see that cmath is being imported:

#include <cmath>
#include <random>
#include <tuple>
#include <vector>
#include <iostream>

At this point, I don't really know how to proceed. Any thoughts or suggestions would really help....

ADDENDUM: For what it's worth, here is my compiler information:

I am attempting to install warp-ctc from https://github.com/baidu-research/warp-ctc

What compiler is in /usr/bin/cc ? You may want to make sure that this compiler is known by nvcc and that the std c++ argument is passed. Otherwise it might consider host code is not c++11. — Florent DUGUET, Dec 15 '17 at 19:31
@FlorentDUGUET - /usr/bin/cc runs through a sries of soft links to /usr/bin/gcc-4.8, which is (as expected) as executable. I'm fairly certain that nvcc sees this, because when I use update-alternatives to change gcc versions, I get different errors — user1245262, Dec 15 '17 at 19:43
The problem is not reproducible with the information in the question. This *might* be a bug in CUDA, in particular the way in which CUDA's `math_functions.h` uses the math header files of the host tool chain (here: gcc). But we don't even know what the code looks like that triggers the compilation error, and what version of CUDA was used to build that code. I would suggest posting an [MCVE](https://stackoverflow.com/help/mcve). — njuffa, Dec 15 '17 at 21:23
@njuffa - I've added more information that I believe corresponds to an MCVE. In terms of expected behavior, I expect that after running cmake, I should be able to run make without experiencing the errors I see. — user1245262, Dec 15 '17 at 21:57
From what I see, the -Xcompiler options do not contain std c++11 flag. You may want to double check that. — Florent DUGUET, Dec 17 '17 at 12:37
Fix seems(?) to be reinstalling everything using Ubuntu 17.04, which is CUDA supported — user1245262, Jan 03 '18 at 15:43
