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: 
android@...115...:~/longjks_new/genode-13.08_longjks/build.linux_x86$ make run/qt5

I can see the error caused by the source code below:
#include <memory>
what is this "memory"? where can i found this "memory"? 
thanks.
