编译环境：ubuntu 20.04
Fast-DDS官网地址：https://fast-dds.docs.eprosima.com/en/latest/
github地址：https://github.com/eProsima
根据官网安装说明进行安装：
Fast-DDS 安装分为三部分：foonathan_memory_vendor， fastcdr，fastrtps
1.安装 cmake g++ python3-pip wget git
sudo apt install cmake g++ python3-pip wget git
- 安装 libasio-dev libtinyxml2-dev
sudo apt install libasio-dev libtinyxml2-dev - 安装 libssl-dev
sudo apt install libssl-dev - 安装 libp11-dev libengine-pkcs11-openssl 和softhsm2 (此步骤可选)
sudo apt install libp11-dev libengine-pkcs11-openssl
sudo apt install softhsm2
softhsm2包创建了一个名为softhsm的新组。需要将当前用户添加到这个组中，才能获取访问权
sudo usermod -a -G softhsm <user>
sudo apt install libengine-pkcs11-openssl
检查p11kit是否能够找到使用的SoftHSM模块
p11-kit list-modules
检查OpenSSL是否能够访问PKCS#11使用:
openssl engine pkcs11 -t
- 安装Gtest， 单元测试时需要，（可选）
git clone https://github.com/google/googletest src/googletest-distribution
6.选择cmake方式安装，本地安装
mkdir ~/Fast-DDS
foonathan_memory_vendor 安装
cd ~/Fast-DDS
git clone https://github.com/eProsima/foonathan_memory_vendor.git
mkdir foonathan_memory_vendor/build
cd foonathan_memory_vendor/build
cmake .. -DCMAKE_INSTALL_PREFIX=~/Fast-DDS/install -DBUILD_SHARED_LIBS=ON
cmake --build . --target install
Fast-CDR 安装
cd ~/Fast-DDS
git clone https://github.com/eProsima/Fast-CDR.git
mkdir Fast-CDR/build
cd Fast-CDR/build
cmake .. -DCMAKE_INSTALL_PREFIX=~/Fast-DDS/install
cmake --build . --target install
Fast-DDS 安装
cd ~/Fast-DDS
git clone https://github.com/eProsima/Fast-DDS.git
mkdir Fast-DDS/build
cd Fast-DDS/build
cmake .. -DCMAKE_INSTALL_PREFIX=~/Fast-DDS/install
cmake --build . --target install
7.全局安装
将本地安装路径修改为 /usr/local/ :
foonathan_memory_vendor: cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/ -DBUILD_SHARED_LIBS=ON
Fast-CDR: cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/
Fast-DDS: cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/
用sudo 安装： sudo cmake --build . --target install
- 运行Fast DDS，需要配置环境变量
临时配置：export LD_LIBRARY_PATH=/usr/local/lib/
永久配置：echo 'export LD_LIBRARY_PATH=/usr/local/lib/' >> ~/.bashrc
