Error after compilation

[jgsimard]

Hi, I have an issue that make me unable to use the code. the error comes up during the build. If if compile with CXX_COMPILER=/usr/bin/g++-4.8, I get this error message

-- The CXX compiler identification is GNU 4.8.5
-- The CUDA compiler identification is NVIDIA 10.0.130
-- Check for working CXX compiler: /usr/bin/g++-4.8
-- Check for working CXX compiler: /usr/bin/g++-4.8 -- broken
CMake Error at /usr/local/share/cmake-3.13/Modules/CMakeTestCXXCompiler.cmake:45 (message):
 The C++ compiler

    "/usr/bin/g++-4.8"

  is not able to compile a simple test program.

  It fails with the following output:

But if I use g++-7, I can compile but I get this error message when I run the test.

I am on Ubuntu 18, python 3.7. Thanks in advance!

There seems to an issue with your g++ compiler. This is unrelated to this repo. I would try reinstalling the compiler or installing a newer version.

Best,
