[英]std::isnan has not been declared, with g++-5
我正在尝试使用nvcc和g ++-5编译程序,但出现此错误。

使用g ++可以正确编译,但是nvcc需要g ++-5。 有谁知道如何解决这个问题? 顺便说一句,一旦我在Ubuntu上运行sudo do-release-upgrade
就开始发生这种情况。
nvcc --version
输出是这样的:

我正在使用c ++ 11进行编译,并且cmath不包含在我的源文件中。 这是我的CMakeLists.txt
。
cmake_minimum_required(VERSION 3.7 FATAL_ERROR)

target_link_libraries(cpu_pcd ${OPENGL_LIBRARIES} glfw ${GLEW_LIBRARIES} ${CUDA_LIBRARIES} pthread)
从C ++ 11开始在<cmath>
声明的std :: isnan和std :: isinf。 该标头包括在内吗? 编译是在C ++ 11或更高版本的模式下完成的吗?
对于那些感兴趣的人,我解决了它,更改了CMakeLists.txt
两行,如下所示:
set(CMAKE_C_COMPILER /usr/bin/gcc-5 CACHE PATH "" FORCE)
set(CMAKE_CXX_COMPILER /usr/bin/g++ CACHE PATH "" FORCE)
现在,在所有人的帮助下,它可以正确编译。
