首先,在CMakeLists.txt文件中添加以下代码,用于检查并启用OpenMP支持: 代码语言:txt 复制 find_package(OpenMP REQUIRED) 接下来,需要在编译选项中添加OpenMP的相关标志。可以使用以下代码将OpenMP标志添加到C和C++编译器选项中: 代码语言:txt 复制 set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}") ...

1. cmake增加对openmp的支持 在CMakeList.txt中增加: FIND_PACKAGE( OpenMP REQUIRED) if(OPENMP_FOUND) message("OPENMP FOUND") set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}") set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}") set(CMAKE_EXE_LINKER_FLAGS "${C...
1、openmp加载,cmake3.9之后内置了openmp find_package(OpenMP)if(OPENMP_FOUND OR OpenMP_CXX_FOUND) set (CMAKE_C_FLAGS"${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}") set (CMAKE_CXX_FLAGS"${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}") set (CMAKE_EXE_LINKER_FLAGS"${CMAKE_EXE_LINKER_FLAGS} ${Ope...
2. cmakelists 在其中添加set(CMAKE_CXX_FLAGS "-fopenmp") 3. 测试demo #include <stdio.h> #include <stdlib.h> #include <omp.h> void Hello(void); int main(int argc, char* argv[]) { int thread_count = 10; #pragma omp parallel for ...
如果您使用 CMake GUI,可以手动设置 OpenMP 的路径。在 CMake GUI 中,您可以: 点击“Configure”按钮,选择 MinGW Makefiles 作为生成器。 点击“Finish”。 在变量列表中查找OpenMP_CXX_FLAGS和OpenMP_CXX_LIBRARIES,确保它们被正确设置。 点击“Generate”生成项目。
-- OPENMP_CXX_FOUND=TRUE -- OPENMP_C_FOUND=TRUE -- OPENMP_FOUND=TRUE -- OpenMP_COMPILE_RESULT_CXX_openmp=TRUE -- OpenMP_COMPILE_RESULT_C_openmp=TRUE -- OpenMP_CXX_FLAGS=-openmp -- OpenMP_CXX_FLAGS_WORK=-openmp -- OpenMP_CXX_FOUND=TRUE ...
定义一些变量、宏的值。该指令一般会出现多次,例如设置C++语法标准:set(CMAKE_CXX_STANDARD11)。相反的指令是unset。 if…else[if]…endif 条件控制语句,注意指令后的括号不可省略: if(WIN32)xxxxelse()# 括号不可省略xxxx endif() find_package 查找指定模块,例如OpenMP。Qt 5项目一般需要:find_package(Qt5CO...
