C++ Poco库的编译和使用

flyfish

环境

Ubuntu18.04
Qt 5.14.2

源码下载地址

https://github.com/pocoproject/poco

编译依次执行

./configure --no-tests --no-samples --config=Linux --omit=Data --shared --static
make
sudo make install

–omit表示排除项目，Data中的SQlite,MySQL,ODBC等排除掉，这里不编译
如果要指定安装目录需要加参数 --prefix，这里是默认目录安装到

/usr/local/lib
/usr/local/include

以http为例说明如何使用

CMakeLists.txt文件配置

cmake_minimum_required(VERSION 3.5)

project(example LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)



# set the POCO paths and libs
set(POCO_PREFIX "/usr/local") # the directory containing "include" and "lib"
set(POCO_INCLUDE_DIR"${POCO_PREFIX}/include")
set(POCO_LIB_DIR "${POCO_PREFIX}/lib")
set(POCO_LIBS
        "${POCO_LIB_DIR}/libPocoNet.so"
        "${POCO_LIB_DIR}/libPocoUtil.so"
        "${POCO_LIB_DIR}/libPocoFoundation.so"
        "${POCO_LIB_DIR}/libPocoNetSSL.so")


add_executable(example
  main.cpp
)
target_link_libraries(example "${POCO_LIBS}")
