写在前面

自己的测试环境是 Ubuntu16.04.
由于ubuntu版本的的限制，使用 ubuntu 的二进制指令 sudo apt-get install libtbb-dev
进行安装 tbb 的版本较低。Ubuntu16.04 二进制安装的 tbb 版本是 4.4~20151115-0ubuntu3，Ubuntu18.04 二进制安装的 tbb 版本是 2017~U7-8.
此教程同样适用于 ubuntu 18.

一、下载

1. 下载源码
   从github 上下载 tbb源码 ，我这里下载 2020_U3 版本。

二、编译

解压

tar -zxvf oneTBB-2020_U3.tar.gz
1

因为要使用 gcc-9 进行编译，所以需要编辑成 gcc-9 形式

cp build/linux.gcc.inc build/linux.gcc-9.inc 
1

编辑 linux.gcc-9.inc 文件：
第15、16行原来是

CPLUS ?= g++
CONLY ?= gcc
1
2

修改为

CPLUS ?= g++-9
CONLY ?= gcc-9
1
2

然后在文件夹 oneTBB-2020_U3/ 中编译

cd oneTBB-2020_U3
make compiler=gcc-9 stdver=c++17 tbb_build_prefix=my_tbb_build
1
2

编译完成后，在 builld/ 文件夹下会看到编译生成的文件夹 my_tbb_build_release/.

三、安装

将 tbb 编译生成的库文件放到对应的 /usr/ 文件夹下：

sudo mkdir /usr/local/tbb-2020_U3

sudo cp -r oneTBB-2020_U3/include /usr/local/tbb-2020_U3/include
# 建立新安装tbb版本的符号链接
sudo ln -s /usr/local/tbb-2020_U3/include/tbb /usr/local/include/tbb

sudo cp -r oneTBB-2020_U3/build/my_tbb_build_release /usr/local/tbb-2020_U3/lib
# 建立新安装tbb版本的符号链接
sudo ln -s /usr/local/tbb-2020_U3/lib/libtbb.so.2 /usr/local/lib/libtbb.so
sudo ln -s /usr/local/tbb-2020_U3/lib/libtbbmalloc.so.2 /usr/local/lib/libtbbmalloc.so
sudo ln -s /usr/local/tbb-2020_U3/lib/libtbbmalloc_proxy.so.2 /usr/local/lib/libtbbmalloc_proxy.so

然后把 库文件的路径写入到 ~/.bashrc ：

echo 'export LD_LIBRARY_PATH=/usr/local/tbb-2020_U3/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc
1
2

然后再次编译程序。

如果出现以下报错，说明现在还是索引到了旧版本的 tbb .

需要卸载掉原来的 tbb，或者把原来的 tbb 库文件备份换个名字（这里把 tbb 库文件备份换个名字）：

cd /usr/lib/x86_64-linux-gnu
# 把原来的 tbb 库文件备份换个名字
sudo mv libtbb.so libtbb.so.bk
sudo mv libtbbmalloc_proxy.so libtbbmalloc_proxy.so.bk
sudo mv libtbbmalloc.so libtbbmalloc.so.bk

# 建立新安装tbb版本的符号链接
sudo ln -s /usr/local/tbb-2020_U3/lib/libtbb.so.2 /usr/lib/x86_64-linux-gnu/libtbb.so 
sudo ln -s /usr/local/tbb-2020_U3/lib/libtbbmalloc.so.2 /usr/lib/x86_64-linux-gnu/libtbbmalloc.so
sudo ln -s /usr/local/tbb-2020_U3/lib/libtbbmalloc_proxy.so.2 /usr/lib/x86_64-linux-gnu/libtbbmalloc_proxy.so

至此，安装tbb完成。
