Undefined Reference to netCDF

[matthew894]

To report a non-security related issue, please provide:

*NETcdf 4.3.1 c++

• Linux Mint, c++, cmake 3.17.3
• Have gone through the install procedure which worked after moving some hdf5 files to the location it was looking for them. Fully completed and tests successful. Then tried to run a simple program with following commands.

include

netCDF::NcFile dataFile("simple_xy.nc", netCDF::NcFile::replace);

program then crashes with the following

/home/matthew/CLionProjects/2DCodeVersion1.0/Diff_Water_Tensor_2D.cpp:14: undefined reference to netCDF::NcFile::NcFile(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, netCDF::NcFile::FileMode)' /home/matthew/CLionProjects/2DCodeVersion1.0/Diff_Water_Tensor_2D.cpp:14: undefined reference tonetCDF::NcFile::~NcFile()'

I get a very similar issue to this when building NetCDF-CXX4 into another C++ project:

• Ubuntu 18.04 run via WSL, g++ 7.5.0, cmake 3.18.2
• Have run through the install proceedure which worked without an issue and passes all tests

I suspect this is an issue of things being compiled with different versions of GCC or against different C++ standards, but I haven't been able to resolve it on my end. I've tried adjusting the cmake to force compilation against C++ by changing line 430 in the CMakeLists.txt file to: SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g -Wall -Wno-unused-variable -Wno-unused-parameter -std=c++11") which seemed to work (i.e., still passed all tests and installed successfully) but it has not resolved my issue.
