How to fix build errors from Qt header files (qchar.h and qbasicatomic.h) when building on mac?

I'm trying to run a Qt project on mac and have an iOS build, however, it doesn't build due to "errors" in qt header files such qchar.h and qbasicatomic.h
Mac specs:
Qt Creator 4.5.0 (based on Qt Qt 5.10.0 Clang 7.0 64 bit)
macOS High Sierra (10.13.6)
Xcode (Version 9.4.1)
I've tried adding CONFIG+= c++11, bu that doesn't help.
Here is the compile issue:
** BUILD FAILED **
The following build commands failed:
ProcessPCH SharedPrecompiledHeaders/precompile-egfdquqtyvgpwccxaewehzkwxdsd/precompile.h.pch ../trunk/precompile.h normal x86_64 c com.apple.compilers.llvm.clang.1_0.compiler

missing package in MXE

I've made a C++ project in Qt. My app shows short video using QMediaPlayer and QVideoWidget.
Everything works fine when I compile it in Qt. I'm a Linux user. The problems starts when I try to cross compile it in MXE.
I have got an error:
Project MESSAGE: Warning: unknown QT: multimediawidgets
and
main.cpp:12:24: fatal error: QMediaPlayer: No such file or directory
compilation terminated.
Makefile.Release:132: recipe for target 'release/main.o' failed
I've add
QT += core gui multimedia multimediawidgets
in my .pro file.
I have noticed that there is no QMultimediaWidget in MXE package
list.
Is there any solution to fix this problem ?

Eclipse compiling error for C++

I just switched from mac to pc and I have to instaled Eclipse for my C++ programing and compiling. I have also instaled Cygwin64 and added the path and things like that. according to the internet it should work now but I get this error:
Problem Occured 'Launching test Debug' has encountered a problem. Error starting process.
In this message 'test' is the name of the class I try to run. Before running I ofcourse Build my project so that is not the problem.
Acording to eclipse there is also an error in the debug map in the makefile file on line 44: #echo 'Building target: $#' (this is what the message says)
My operating system is windows 8 64 bit.
