请问在Broadcom 7405的板子上如何编译qt-everywhere-opensource-src-4.6.2.tar.gz？
congfigure应该带哪些参数？
并且只能用DirectFB启动！
谢谢！

./configure -opensource -static -prefix /home/stb/qt -embedded -arch mips -little-endian -host-little-endian -xplatform qws/linux-mips-g++ -plugin-gfx-directfb -no-libpng
qmake.conf已经修改，加上了
QT_CFLAGS_DIRECTFB = -I/home/stb/Broadcom/nexus/lib/directfb/src/DirectFB-1.0.0/build.97405B0/opt/dfb/include/directfb -D_REENTRANT
QT_LIBS_DIRECTFB = -L/home/stb/Broadcom/nexus/lib/directfb/src/DirectFB-1.0.0/build.97405B0/opt/dfb/lib/-ldirect -ldirectfb -lfusion
但是，总是报如下错误：
Creating qmake. Please wait...
gmake: Nothing to be done for `first'.
The DirectFB screen driver functionality test failed!
You might need to modify the include and library search paths by editing
QT_CFLAGS_DIRECTFB and QT_LIBS_DIRECTFB in
/home/stb/qt-everywhere-opensource-src-4.6.2/mkspecs/qws/linux-mips-g++.
google了半天，没有发现解决的方法，郁闷。

加上-v后，有如下错误：

libdirectfb.so是用mips-linux-gcc编译的，mips-linux-g++竟然不认识？百思不解中~
#4 [davidchiu 03-17 19:30]
原来libdirectfb.so是用mipsel-linux-gcc编译的，这是-little-endian mips，所以用-big-endian mips-linux-g++编译，导致无法识别，但是
在的configure中已经指明了-little-endian，但是为什么还是用mips-linux-g++，而没有用mipsel-linux-g++呢？
谁能指明一下方向，谢谢~
累呀~
先手工将mipsel-linux-g++修改mips-linux-g++，试试瞒天过海法~
#5 [davidchiu 03-18 12:39]
晕死了，哎，头昏了！
-little-endian将目录/mkspecs/qws/linux-mips-g++/qmake.conf 将其中的mips-linux-gcc、mips-linux-g++改为mipsel-linux-gcc、mipsel-linux-g++即可，搞什么瞒天过海法，汗颜！
有人知道-qt-gfx-directfb同-plugin-gfx-directfb有什么区别吗？
-qt-gfx-directfb同-plugin-gfx-directfb的区别：
-qt-gfx-directfb- ...Enable a directfb in the Qt Library.
-plugin-gfx-directfb- Enable directfb as a plugin to be linked to at runtime.
