I'm trying to make a GUI for ROS and I get these errros.

Please help guys I'm about to finish my master thesis and I stuck here for a long time. I can understand that is something with the boost library. For the reason that I had in my laptop QT 4 because, ROS when create the QT package the CMakeLists were for QT4. I made some changes in CMakeLists and I managed to run cmake without problems. But I change the version of Boost library. First I installed version 1.55 then 1.52 and now I have version 1.69.
The version of QT is Qt Creator 4.9.2
Based on Qt 5.12.4 (GCC 7.4.0, 64 bit)
Consider that is the ROS plugin. I'm a little confused about versions in QT. Anyway, here is the CMakeList

##############################################################################

# exporting anything. 
catkin_package()

Please show your code but I guess you have a using namespace FOO somewhere in your header. Remove it.

Here is the code. Indeed I had a namespace, I remove it errors about boost has gone but now I have this error.

Hi,

Your header is wrong. You are missing the forward declaration of the "Ui::MainWindow" class, the ui variable is also wrong as it should be a "Ui::MainWindow".

Hello. I don't get what I should change. Can you give me an example?

@SGaist already told you what to do - you member 'ui' is wrong - it must be Ui::MainWindow.

He told me to delete namespace. I thought that he meant
namespace Ui {
class MainWindow;
}
and I deleted this. I wrote back again and now works. Thank you.
