Compiling Poco with MinGW on Windows

I need to compile poco with MinGW so that I can use it in Qt Creator, but I can’t figure out how to do it, I managed to compile poco in Visual Studio, but I can’t use these libraries in Qt Creator.

In addition to Cesar's answer (here instead of adding a comment for formatting) you need something like this in your .pro file:

INCLUDEPATH += "<path_to_poco_include_dir>"
LIBS += -L"<path_to_poco_lib_dir>" -l<poco_lib> -l<poco_lib>

For example, in my case, I would have this (for debug builds):

INCLUDEPATH += "C:/Dev/lib/poco/poco143/Debug/include"
LIBS += -L"C:/Dev/lib/poco/poco143/lib" -lPocoFoundationd -lPocoUtild

Then you can refine this a bit by creating settings for both debugging and release:

LIB_HOME = "C:/Dev/lib/"
POCO_HOME = $${LIB_HOME}poco/poco143/

# SEE http://www.qtcentre.org/threads/23655-Does-Qt-Creator-understand-debug-release-scopes-in-pro-files
# OR http://www.qtcentre.org/threads/30430-How-to-set-pro-file-about-debug-and-release
####
CONFIG(debug, debug|release) {
CONFIG -= debug release
CONFIG += debug
}

CONFIG(release, debug|release) {
CONFIG -= debug release
CONFIG += release
}
####

debug {
POCO_DEBUG = d
POCO_PATH = $${POCO_HOME}Debug
}

release {
POCO_DEBUG =
POCO_PATH = $${POCO_HOME}Release
}

INCLUDEPATH += "$${POCO_PATH}/include"
LIBS += -L"$${POCO_PATH}/lib" -lPocoFoundation$${POCO_DEBUG} -lPocoUtil$${POCO_DEBUG}

Hope this helps.
