怎么下载安装包，请参见如何从github上下载对应安装包。（其实就是从GitHub上spdlog 的仓库下载就好）
这里介绍怎样安装spdlog这个日志管理使用的库。
- 首先将源码包解压到自己的目录下。
[zry@localhost package]$ ls date-master git-2.34.1 ormpp-master Python-3.8.0 spdlog-1.x sqlpp11-main
- 进入到spdlog解压文件夹内
[zry@localhost package]$ cd spdlog-1.x/ [zry@localhost spdlog-1.x]$ ls appveyor.yml bench build cmake CMakeLists.txt example include INSTALL LICENSE logos README.md scripts src tests
- 创建build 目录，用来存放cmake编译 相关内容
[zry@localhost spdlog-1.x]$ mkdir build
- 进入到build目录内
[zry@localhost spdlog-1.x]$ cd build/
- 进行cmake 编译，命令
cmake ..
[zry@localhost build]$ cmake .. -- The CXX compiler identification is GNU 8.3.1 -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /opt/rh/devtoolset-8/root/usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Build spdlog: 1.12.0 -- Looking for C++ include pthread.h -- Looking for C++ include pthread.h - found -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE -- Build type: Release -- Generating example(s) -- Generating install -- Configuring done -- Generating done -- Build files have been written to: /home/zry/package/spdlog-1.x/build
- 进行编译 命令
make -j
[zry@localhost build]$ make -j [ 10%] Building CXX object CMakeFiles/spdlog.dir/src/spdlog.cpp.o [ 20%] Building CXX object CMakeFiles/spdlog.dir/src/stdout_sinks.cpp.o [ 30%] Building CXX object CMakeFiles/spdlog.dir/src/color_sinks.cpp.o [ 40%] Building CXX object CMakeFiles/spdlog.dir/src/file_sinks.cpp.o [ 50%] Building CXX object CMakeFiles/spdlog.dir/src/async.cpp.o [ 60%] Building CXX object CMakeFiles/spdlog.dir/src/cfg.cpp.o [ 70%] Building CXX object CMakeFiles/spdlog.dir/src/bundled_fmtlib_format.cpp.o [ 80%] Linking CXX static library libspdlog.a [ 80%] Built target spdlog [ 90%] Building CXX object example/CMakeFiles/example.dir/example.cpp.o [100%] Linking CXX executable example [100%] Built target example
- 编译完成之后可以进行测试 在 build 目录下会有一个
example文件夹，进入后执行./example可以看到测试结果。
