ld without -lstdc++ cannot find doctest - qt

I am working on a project under Windows and Ubuntu using CMake and CLang. On Ubuntu, I can build it OK with a shell script and could build it using Qt 5.5.1 (Creator 3.5.1). After upgrading to Qt 5.14.0 (Creator 4.11.1), there are over 1200 link errors where doctest cannot be found.
Captured compiler output:

and hundreds of similar errors in several files.
The shell script produces the following output.
"/usr/bin/ld" ... -lstdc++ -lm -lgcc_s -lgcc -lpthread -lc -lgcc_s -lgcc ...
I have no idea why -lstdc++ is added or not but assume that it identifies the required doctest library. Is there an option that can be added to CMakeList.txt to correct this issue?

How can I link with the QPid Proton library's static libs?

I'm trying to link against the QPid Proton library, using static libs, and am getting lots of link errors. I am able to build with the shared libraries, but for this project we need to use static libs.
Here's the CMake file:
cmake_minimum_required(VERSION 3.0.0)
project(test-qpid VERSION 0.1.0)
include(CTest)
enable_testing()
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -no-pie " )
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -v -std=c++17 -lpthread -static-libgcc -static-libstdc++ -fdiagnostics-color=auto")
set(THREADS_PREFER_PTHREAD_FLAG ON)
add_library(libpthread STATIC IMPORTED)
set_target_properties(libpthread PROPERTIES IMPORTED_LOCATION /usr/lib/x86_64-linux-gnu/libpthread.a)
set_target_properties(libpthread PROPERTIES INTERFACE_INCLUDE_DIRECTORIES /usr/include)
add_executable(test-qpid main.cpp)
find_library(QPID_PROTON_CORE NAMES qpid-proton-core-static)
if (NOT QPID_PROTON_CORE)
message(FATAL_ERROR, "QPid Proton core static library not found")
endif()
find_library(QPID_PROTON_PROACTOR NAMES qpid-proton-proactor-static)

endif()
find_library(QPID_PROTON NAMES qpid-proton-static)
if (NOT QPID_PROTON)
message(FATAL_ERROR, "QPid Proton static library not found")
endif()
find_library(QPID_PROTON_CPP NAMES qpid-proton-cpp-static)
if (NOT QPID_PROTON_CPP)
message(FATAL_ERROR, "QPid Proton CPP static library not found")
endif()
set(CPACK_PROJECT_NAME ${PROJECT_NAME})

set(LIBS ${QPID_PROTON_CORE} ${QPID_PROTON} ${QPID_PROTON_PROACTOR} ${QPID_PROTON_CPP})
target_link_libraries(test-qpid ${LIBS} libpthread)
include(CPack)
Here is a snippet of the output I'm seeing (there are lots more, which I've omitted for brevity):

I've been Googling for answers for days and have gotten nowhere. If anyone has any experience with QPid Proton I'd greatly appreciate some suggestions.

You are using an MSVC build of Qt and thus cannot use MinGW's make.
The error you get when using nmake indicates that you haven't set up a MSVC build environent. See Build C/C++ code on the command line in the MSVC docs for more information.

native build qt5.7.1 on raspberry pi get errors: /usr/lib/arm-linux-gnueabihf/libQt5Quick.so.5: undefined reference to `QV8Engine::toVariant

i tried to build qt 5.7.1 on pi3 following this instruction:
https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi
the source package i use is:
qt-everywhere-opensource-src-5.7.1.tar
configure as:
./configure -v -opengl es2 -force-pkg-config -device linux-rpi3-g++ -device-option CROSS_COMPILE=/usr/bin/ -opensource -confirm-license -optimized-qmake -reduce-exports -release -qt-pcre -qt-xcb -make libs -no-use-gold-linker -prefix /usr/local/qt5
The instruction is using "linux-rasp-pi-g++", but i think it should be linux-rpi3-g++ for Rpi3.
Make, and i get errors like:

so, how can i fix this problem?
thanks.

I've solved this problem, and there is a new problem now.
Before native building qt on pi, I installed qt by:
sudo apt-get install qt5-default, and other qt5 packages.
Although I have :
sudo apt-get remove those packages, it may still works.
so I formatted the SD card and re-burned an Raspbian image, followed the instructions, "make", and the problem is gone.
but now I have another problem.
When I "make install", I get this error:

I found there are 3 directories in qtlocation/src/3rdparty
clip2tri
clipper
poly2tri
and 3 file in qtlocation/lib:
libclip2tri.prl
libclipper.prl
libpoly2tri.prl
but no lib files.
I checked the build log, it seems cpp file in the directoriy qtlocation/src/3rdparty are not compiled,

Getting unresolved external symbol when trying to compile a Qt application

I created a simple GUI application in QtCreator (QT 4.8.2) and added a function to check the network connectivity:
bool MainWindow::CheckNetworkConnectivity()
{
QList<QNetworkInterface> interface = QNetworkInterface::allInterfaces();
for(int i = 0; i < interface.count();i++)
{
QNetworkInterface inface = interface.at(i);
if(inface.IsUp && !inface.IsLoopBack)
{
ui->lstLog->addItem(inface.name()+QDateTime::currentDateTime().toString("h:m:s ap"));
ui->chkConStatus->setChecked(true);
}
else{
ui->chkConStatus->setChecked(false);
}
}
return ui->chkConStatus->checkState();
}
After that any attempts to compile the code generates the following errors:
15:21:11: Running steps for project MasterVPN...

Error while building/deploying project MasterVPN (target: Desktop)
When executing step 'Make'
Can someone please point out what the cause could be?

The linker is indicating that is can not find the required functionality. This is contained within QtNetwork4.lib (if you're on a Windows platform) or the equivalent library for your platform. So you have to tell the linker that it needs to link against this library. The network module is the required one, so instead of just
QT += core gui
at least make that
QT += core gui network
That should fix the linker errors you see.
