Linux

1、获取其代码仓库（外网）

方式1：git clone

1 git clone https://github.com/oneapi-src/oneTBB

View Code

 

方式2：release 直接点击下载

Releases · oneapi-src/oneTBB

 

 

2、TBBConfig.cmake 配置 复制到系统中cmake

 

 1 #1.先去对应的系统中library中创建/cmake/TBB
 2 cd /usr/local/lib
 3 mkdir cmake && cd cmake
 4 mkdir TBB
 5 
 6 #2.再去 oneapi-tbb-2021.11.0/lib/cmake/中 
 7 cd oneapi-tbb-2021.11.0/lib/cmake
 8 
 9 #3.修改文档
10 vim TBBConfig.make
11 #里面有一个 TBB_FOUND FALSE -> TRUE
12 
13 #4.复制到 /usr/local/lib/cmake/TBB
14 cp TBBConfig*.cmake /usr/local/lib/cmake/TBB/.
15 
16 #5.检查
17 ls /usr/local/lib/cmake/TBB/

3、TBBConfig.cmake 配置 复制到系统中cmake

3.1 查看自己是系统是32位还是64位

 

3.2 复制到/usr/local/lib/*.so

 

 1 # 1. 到相应的目录下
 2 cd /oneapi-tbb-2021.11.0/lib
 3 # 2. 查看自己系统是多少位系统
 4 uname -m #x86_64 = 64位  |  ( i686 | i386 ) = 32位
 5 # 3. 去相应的文件夹 64位去intel64 ; 32位就去ia32
 6 cd intel64/gcc4.8
 7 # 4. 复制到/usr/local/lib
 8 cp *.so* /usr/local/lib
 9 # 5. 检查是否 成功复制了？
10 ls /usr/local/lib/*tbb* | wc -l

4、复制 头文件*.h 到 include下

 

1 # 1. 进入相应的目录下
2 cd oneapi-tbb-2021.11.0/include/oneapi
3 # 2. 复制目录下的东西至/usr/local/include即可
4 cp -rf ./* /usr/local/include
5 # 3. 检查一下是否 成功复制到
6 ls /usr/local/include/tbb
