我正在尝试编译cutecash（一个qt项目）并遇到一些麻烦。我只是在做标准：
cmake .
make
然而，我遇到的错误是无法找到QMainWindow和QString等等。这是错误：
In file included from /home/username/code/gnucash/src/gnc/fpo/ViewletView.hpp:14:0,

看似相当重要的东西：
error: #error "This file was generated using the moc from 5.0.1. It"
error: #error "cannot be used with the include files from this version of Qt."
error: #error "(The moc has changed too much.)"
因此，每当我尝试安装qt5-default（在ubuntu上）时，我必须删除qt4-default。如果我现在尝试编译，我会因为无法完成QMainWindow和其他一些部分（例如QAbstractItemDelegate）而遇到同样的问题。
我也收到这个警告：
#error "You must build your code with position independent code if Qt was built with -reduce-relocations. " "Compile your code with -fPIC or -fPIE."
除了一些新的错误之外，由于无法找到物品而出现这些错误。我在ubuntu 13.04上。
