protobuf开发环境部署

安装依赖包

wget https://copr.fedorainfracloud.org/coprs/ngompa/musl-libc/repo/epel-7/ngompa-musl-libc-epel-7.repo -O /etc/yum.repos.d/ngompa-musl-libc-epel-7.repo --no-check-certificate
yum install -y musl-libc-static

安装gcc-9.5

yum install -y m4 gcc-c++
cd /usr/local/src
# 下载gcc9.5.0源码
wget http://ftp.gnu.org/gnu/gcc/gcc-9.5.0/gcc-9.5.0.tar.gz
tar -zxvf gcc-9.5.0.tar.gz
# 进入gcc目录安装
cd gcc-9.5.0
# 下载某些依赖包
./contrib/download_prerequisites
# 创建bulid文件夹
mkdir build
cd build
../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
# 编译安装,此过程耗时较长
make && make install


mv /usr/bin/gcc /usr/bin/gcc_bak
ln -s /usr/local/gcc/bin/gcc /usr/bin/gcc
mv /usr/bin/g++ /usr/bin/g++_bak
ln -s /usr/local/gcc/bin/g++ /usr/bin/g++

cp ./stage1-x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6.0.28 /lib64
rm  /lib64/libstdc++.so.6
ln -s /lib64/libstdc++.so.6.0.21 /lib64/libstdc++.so.6

安装boost 1.65.1

下载安装包https://boostorg.jfrog.io/artifactory/main/release/1.65.1/source/boost_1_65_1.zip

解压后执行：

./bootstrap.sh
./b2 install --prefix=/usr/local/lib/boost

在/etc/profile文件中添加
export CPLUS_INCLUDE_PATH=/usr/local/lib/boost/include:$CPLUS_INCLUDE_PATH
export LIBRARY_PATH=/usr/local/lib/boost/lib:$LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/lib/boost/lib:$LD_LIBRARY_PATH
之后，执行source /etc/profile

安装c++插件protobuf-cpp

wget https://github.com/protocolbuffers/protobuf/releases/download/v21.5/protobuf-cpp-3.21.5.zipunzip protobuf-cpp-3.21.5.zip
cd protobuf-3.21.5
./configure
make -j20
make install

安装python插件protobuf-python

需要提前安装好python3.8

wget https://github.com/protocolbuffers/protobuf/releases/tag/v21.5/protobuf-python-4.21.5.zip
unzip protobuf-python-4.21.5.zip
cd protobuf-4.21.5
cd python
python3 setup.py build
python3 setup.py install

拷贝依赖库文件

cp ./src/.libs/libprotobuf.so.32.0.5 /lib64
ln -s /lib64/libprotobuf.so.32.0.5 /lib64/libprotobuf.so.32

常见问题：

问题：PCL在linux下运行PCLVisualizer报错： undefined reference to symbol ‘pthread_condattr_setclock@@GLIBC_2.3.3‘
解决：https://zhuanlan.zhihu.com/p/132481781

问题：Could NOT find Boost (missing: Boost_INCLUDE_DIR)
解决：修改CMakelist加入：

set(BOOST_ROOT  /usr/local/lib/boost/include)
set(Boost_LIBRARY_DIRS /usr/local/lib/boost/lib)

问题：undefined reference to `std::__cxx11::collate<wchar_t> const& std::use_facet<std::__cxx11::collate<w
解决：修改CMakelist加入：set(CMAKE_CXX_COMPILER "/bin/g++")
