Hi,

This is the QXmpp.pri file

QXMPP_VERSION = 0.4.0
QXMPP_INCLUDEPATH = $$PWD/src/base $$PWD/src/client $$PWD/src/server

CONFIG(debug, debug|release) {

} else {
QXMPP_LIBRARY_NAME = qxmpp
}

QXMPP_INTERNAL_LIBS += -lspeex
} else:symbian {
QXMPP_INTERNAL_INCLUDES = $$APP_LAYER_SYSTEMINCLUDE
QXMPP_INTERNAL_LIBS = -lesock
} else:win32 {
QXMPP_INTERNAL_LIBS = -ldnsapi -lws2_32
}

# Libraries for apps which use QXmpp
symbian {
# Symbian needs a .lib extension to recognise the library as static
QXMPP_LIBS = -l$${QXMPP_LIBRARY_NAME}.lib
} else {

}

# Determine library type (lib or staticlib)
isEmpty(QXMPP_LIBRARY_TYPE) {
QXMPP_LIBRARY_TYPE = staticlib
}
contains(QXMPP_LIBRARY_TYPE,staticlib) {
# FIXME: we should be able to use the link_prl option to automatically pull
# in the extra libraries which the qxmpp library needs, but this does not
# seem to work on win32, so we specify the dependencies here:

}

Is /usr/local/lib in your library search path? Is libqxmpp.so present in that directory?

[jeyanthinatarajan]

Hi,

Thanks for the reply wysota

I included the library file in /usr/local/lib but still i am getting the same error...

[ChrisW67]

As far as I can tell your PRO file uses the default linker library path and a relative folder called "../../src" only (i.e. the LIBS -L options). Unless libqxmpp.so is installed in one of those locations (the relative location is prone to being not what you thought) then things will not be in the correct locations for include paths and libraries. If you have not installed qxmpp according to the README (http://code.google.com/p/qxmpp/source/browse/README) file in its source bundle then do so. If you used the defaults on a UNIX-like machine then is should be installed into /usr/local/lib, include etc. and often will Just Work.

Ultimately your PRO should only need:


QXMPP_PREFIX = /usr/local
INCLUDEPATH += $${QXMPP_PREFIX}/include
LIBS += -L$${QXMPP_PREFIX}/lib -lqxmpp

in order to use the library (and not the files you are copying form the actual qxmpp build).
