GICI —编译运行glog报错

检查以下几点

1. cmake版本要大于3.22

先看cmake版本够不够，出现以下错误

CMake Error at CMakeLists.txt:1 (cmake_minimum_required): CMake 3.22 or higher is required. You are running version 3.15.0 -- Configuring incomplete, errors occurred!

升级cmake版本，按步骤执行

sudo apt remove -y cmake sudo apt autoremove -y # 下载 3.22.6 版本的 Linux x86_64 安装包 wget https://github.com/Kitware/CMake/releases/download/v3.22.6/cmake-3.22.6-linux-x86_64.sh # 赋予执行权限 chmod +x cmake-3.22.6-linux-x86_64.sh # 执行安装脚本，指定安装路径为 /usr/local，跳过许可协议 sudo ./cmake-3.22.6-linux-x86_64.sh --prefix=/usr/local --skip-license # 刷新系统命令缓存（确保能识别新的 cmake 命令） hash -r cmake --version

cmake version 3.22.6 CMake suite maintained and supported by Kitware (kitware.com/cmake).

2.先安装 gflags再安装glog

sudo git clone https://github.com/gflags/gflags.git cd gflags/ sudo mkdir build && cd build sudo cmake .. -DGFLAGS_NAMESPACE=google -DCMAKE_CXX_FLAGS=-fPIC .. sudo make -j16 sudo make install

3. glog 安装0.4.0版本

因为我在编译GICI时出现了下面这种问题，

/usr/bin/ld: libgici.so: undefined reference to `google::base::CheckOpMessageBuilder::CheckOpMessageBuilder(char const*)'
/usr/bin/ld: libgici.so: undefined reference to `google::LogMessage::LogMessage(char const*, int, int)'/usr/bin/ld: libgici.so: undefined reference to `google::base::CheckOpMessageBuilder::~CheckOpMessageBuilder()'
/usr/bin/ld: libgici.so: undefined reference to `google::base::CheckOpMessageBuilder::ForVar2()'
/usr/bin/ld: libgici.so: undefined reference to `google::kLogSiteUninitialized'
/usr/bin/ld: libgici.so: undefined reference to `google::LogMessageFatal::LogMessageFatal(char const*, int, google::CheckOpString const&)'
/usr/bin/ld: libgici.so: undefined reference to `google::InitVLOG3__(int**, int*, char const*, int)'
/usr/bin/ld: libgici.so: undefined reference to `google::base::CheckOpMessageBuilder::NewString[abi:cxx11]()'
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/gici_main.dir/build.make:173: gici_main] Error 1
make[1]: *** [CMakeFiles/Makefile2:189: CMakeFiles/gici_main.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

修改了cmakelist中 glog的路径为绝对路径也不行，于是重新安装了glog。但是安装过程中也没有任何问题。最后的最后安装了一个0.4.0版本，编译成功了................

# 进入你的常用源码目录（比如家目录） cd ~ # 下载 glog 0.4.0 wget https://github.com/google/glog/archive/refs/tags/v0.4.0.tar.gz # 解压 tar -xzvf v0.4.0.tar.gz # 进入源码目录 cd glog-0.4.0 # 创建并进入 build 目录 mkdir build && cd build # 配置 CMake (生成共享库) cmake .. # 编译 (使用4核加速) make -j4 # 安装到系统目录 (需要密码) sudo make install

然后删除之前的build ，重新编译gici 才成功
