那位帮我看看这个问题，DFB是别人公司人移植的，发给我出了问题，一板子中间经了一个公司，他们也不懂，只能我自己慢慢找，明明有那个文件 他怎么说没有呢，是不是环境变量那设置错了，
export LD_LIBRARY_PATH=/usr/local/lib/:/applications/mipseldir/lib:/usr/local/bin/directfb/1.4/:$LD_LIBRARY_PATH
export DFBARGS=module-dir=/applications/mipseldir/lib/directfb-1.4-15-pure

这个so文件目录在哪，加到LD_LIBRARY_PATH了没有。
