尚未使用g ++-5聲明std :: isnan

Question

我正在嘗試使用nvcc和g ++-5編譯程序，但出現此錯誤。

使用g ++可以正確編譯，但是nvcc需要g ++-5。 有誰知道如何解決這個問題？ 順便說一句，一旦我在Ubuntu上運行sudo do-release-upgrade就開始發生這種情況。

nvcc --version輸出是這樣的：

nvcc: NVIDIA (R) Cuda compiler driver

Built on Tue_Jan_10_13:22:03_CST_2017

g++-5 --version輸出是這樣的：

我正在使用c ++ 11進行編譯，並且cmath不包含在我的源文件中。 這是我的CMakeLists.txt 。

cmake_minimum_required(VERSION 3.7 FATAL_ERROR)
set(CMAKE_C_COMPILER /usr/bin/gcc-5 CACHE PATH "" FORCE)
set(CMAKE_CXX_COMPILER /usr/bin/gcc-5 CACHE PATH "" FORCE)

cuda_add_library(kernel src/update_particles.cu)
cuda_add_executable(cpu_pcd ${SRC})

set_target_properties(cpu_pcd

target_link_libraries(cpu_pcd kernel)
target_link_libraries(cpu_pcd ${OPENGL_LIBRARIES} glfw  ${GLEW_LIBRARIES} ${CUDA_LIBRARIES} pthread)

Answer 1

您需要使nvcc在C++11模式下運行主機C ++編譯器（將此選項直接傳遞給gcc是不夠的）：

 nvcc -Xcompiler "-std=c++11"

細節可以在這里找到

cuda 5.0支持的c ++版本

使用CUDA和C ++ 11時出錯

Answer 2

從C ++ 11開始在<cmath>聲明的std :: isnan和std :: isinf。 該標頭包括在內嗎？ 編譯是在C ++ 11或更高版本的模式下完成的嗎？

Answer 3

對於那些感興趣的人，我解決了它，更改了CMakeLists.txt兩行，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)

現在，在所有人的幫助下，它可以正確編譯。
