官网下载: https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html?packages=oneapi-toolkit&oneapi-toolkit-os=linux&oneapi-lin=offline
在这里插入图片描述
填写邮件和国家,下面可以看到下载和安装链接,依次执行即可:

安装后查看:

$ ls /opt/intel/oneapi/
2025.0   compiler       dnnl       ipp        mkl                   pti          tcm

一个cmake和makefile的例子, 我需要mkl, openmp:
makefile:

CC = g++

ONEAPI_PATH=/opt/intel/oneapi

CXXFLAGS = -std=c++14 -I${ONEAPI_PATH}/mkl/latest/include
LDFLAGS = -L${ONEAPI_PATH}/mkl/latest/lib/intel64 -L${ONEAPI_PATH}/compiler/latest/lib

LDLIBS = -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -liomp5 -lpthread -lm -ldl
# 在运行时查找动态库的路径
RPATH_FLAGS = -Wl,-rpath,${ONEAPI_PATH}/mkl/latest/lib/intel64 -Wl,-rpath,${ONEAPI_PATH}/compiler/latest/lib

# 项目名和源文件
TARGET = test_single
SRC = test_single.cpp

all: $(TARGET)

$(TARGET): $(SRC)
	$(CC) $(CXXFLAGS) $(LDFLAGS) $^ -o $@ $(LDLIBS) $(RPATH_FLAGS)

clean:
	rm -f $(TARGET)

cmakelists:

cmake_minimum_required(VERSION 3.10)
project(MyMKLProject)

# 设置 C++ 标准
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

# Intel MKL options
set(MKL_ROOT "/opt/intel/oneapi/mkl/latest")

# 包含 MKL 头文件目录
include_directories(${MKL_ROOT}/include)

# 链接
link_directories(${MKL_ROOT}/lib/intel64)
link_directories(/opt/intel/oneapi/compiler/latest/lib)

# 添加执行文件
add_executable(test_single test_single.cpp)

# 链接到 MKL 库
target_link_libraries(test_single
    mkl_intel_lp64    # LP64 model
    mkl_sequential    # Single-threaded
    mkl_core          # Core MKL routines
    iomp5             # Intel OpenMP library (if using MKL with OpenMP)
    pthread
    m
    dl
)
