Some error in using Qt on genode

[longjks]

Hello,
I just want to development Qt application on Genode.
However I am new to Qt. I do not know how to use Qt on Genode.
I found there are some example Qt applications on genode-13.08/libports/src/qt5.
I try to run qt5.run on Platform of linux_x86, however it can not work.

here is my steps:
1) ./tool/create_builddir linux_x86 BUILD_DIR=build.linux_x86
2) cd build.linux_x86
3) make run/qt5

here is the log:

I can see the error caused by the source code below:
#include <memory>

what is this "memory"? where can i found this "memory"?

thanks.
