应该将将这部分的修改放到qmake.conf的QT_CFLAGS_DIRECTFB和QT_LIBS_DIRECTFB中，但我试过有点问题，这两个变量好像被修改成系统的/usr/lib/directfb了，所以我直接修改在里。 其中用到了一个libtangox.so，这是我对smp865x的sdk的抽象，包含directfb的初始化等。注意包含此库的路径。内容为：TARGET =

examples -nomake tools -nomake docs -no-qt3support -plugin-gfx-directfb然后makemake install 到/usr/local/Trolltech/QtEmbedded-4.7.3-mips/中6，开发板上运行 首先配置好环境变量LD_LIBRARY_PATH，注意包含sdk路径，libtangox.so路径，qt库路径。 然后到QtEmbedded-4.7.3-mips/demos下去运行 ./affine -qws -display directfb 到这一步后，界面上能显示出东西。但鼠标键盘不能操作，并且CPU占用率很高，还有显示的东西有点问题，跟PC上不一样
