我按照以下步骤使用postgresql构建soci并使用soci构建我的应用程序。
1）从git到目录/ home / sujith / soci / src的结帐代码
sujith@sujith-VirtualBox:~/soci/src$ pwd
/home/sujith/soci/src
sujith@sujith-VirtualBox:~/soci/src$ ls
appveyor.yml AUTHORS bin CHANGES cmake CMakeLists.txt CTestConfig.cmake docs include languages LICENSE_1_0.txt README.md src tests TODO Vagrantfile www
sujith@sujith-VirtualBox:~/soci/src$
2）完成cmake
sujith@sujith-VirtualBox:~/soci/build$ pwd
/home/sujith/soci/build
sujith@sujith-VirtualBox:~/soci/build$ cmake -G "Unix Makefiles" -DWITH_POSTGRESQL=ON ../src
