ubuntu下交叉编译树莓派qt5问题！

creepsl

主机系统是ubuntu
树莓派用的是2015-11-21-raspbian-jessie
交叉工具链用的官方github上面的tools（github.com/raspberrypi/tools.git）
Qt源码用的qt-everywhere-opensource-src-5.5.1
configure的参数用了
sudo ./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=~/rpi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot /mnt/raspberrypi2 -prefix /usr/local/Qt5Embedded
基本是官方官网提供的那些，因为路径没有设环境变量，所以直接打的地址
最后在make的过程中出现如下问题

在最上面的那个问题出现的没有那个文件或者目录最后找的时候找到了，查找相关资料怀疑是raspbian用的gcc和工具链的gcc版本不一致，但是不知道对不对，我查过树莓派的gcc版本是4.9.2。交叉工具链的gcc版本是4.8.3,。但是在之前直接交叉编译一些小文件的时候是可以做到的，在pc编译传到树莓派运行，但是现在在交叉编译qt5的时候出现了问题。不知道有没有大神指教，才开始弄得这个东西，好多都还是不懂。

看你的提示啊，它说 libz , libdl， librt,libm都没有，说明你没有安装，你要先安装一下 ，然后它指出的是  /mnt/raspberrypi2/usr/lib/arm-linux-gnueabihf/  ,说明是你的树莓派上没有安装，要在树莓派上这些lib文件，用 sudo apt-get install

那个/mnt/raspberrypi2下面是挂载的从树莓派官网下的镜像文件呀，直接挂载的。

你看这是截图，我刚弄的，在它说没有的地方我实际上找到了！

你的ubuntu用的是64还是32位系统啊，感觉和这个有关

32位的，最后问题找出来了。找不到的那几个文件是用绝对路径指向的一个链接文件，所以找不到，用权限复制了一个到相应的目录下，最后make成功，昨天晚上全部编译完成。但是没有测试是否成功。
