You are probably mixing architectures (your library is compiled for 32 bit, but you are compiling in a 64 bit environment). You need to link to a correct architecture.

thanks for your reply! what i need to do? can u explain the detail? many thanks!

Use 64 bit cimg library instead of a 32 bit one. I know to little about your setup (OS, .pro filecode showing library inclusion, Qt version) to say much more.

Many thanks sir! the pro file is:
TEMPLATE = app
INCLUDEPATH += /opt/X11/includeInput
HEADERS += args.h block.h CImg.h graph.h main.h
SOURCES += args.cpp argsgraph.cpp graph.cpp main.cpp maxflow.cppmy os is:
10. 9.4
my qt version is:
qt creator 3.0.0 Based on QT 5.2.0(Clang 4.2(Apple), 64 bit)

You are missing LIBS in there. It is not enough to include the header of a library, you need to tell the linker (ld) where it can find the library, so that it can be linked.
See "the documentation":http://qt-project.org/doc/qt-5/qmake-variable-reference.html#libs.

Really thank u, Sir! But the CImg's homage said that it doesn't need to compile it or do sth else, just include the Cimg.h, here is the link http://sourceforge.net/projects/cimg/files/
Sorry for my poor english, i am not a native spearer, also it works on other people's red hat , but I don't know how to deal with here on my mac, can I send the code to your and let u have a look? if it's possible. Sorry to bother u!

I see. It is uncomon to see a single header being named a library. I am not familiar with it. I suspect you need to first compile that into a library, and then include that library in your source code. But maybe it is intended to work in a different way.
