Are your installed QT,QTADA libraries compatible with the Mingw-Toolchain? Also regarding the bitness 32/64. The Versions of your libraries and the compile/linker command would be helpful.

I'm trying to port a SwiftUI view into react native following this guide. It build fine in swift project but not in a react native project.
I'm getting the following error:

To reproduce I made this Github repo
Copy those files in a react native project and try to build. Make sure to replace the header file import with your test project name "<Replace This>-Swift.h"
My build target is iOS 13.5 iPhone 11 Pro Max simulator.
I have build the gst-build Gstreamer 1.18 version, after installing libsoup2.4-dev and I can see that the dependency is detected:
|Dependency libsoup-2.4 found: YES 2.62.1 (cached).
Later on, compiling the project that I am developing related with WebRTC I have the following issue. How can I solve it?

There are several posts citing this (or similar) undefined references, but none of those was of help.
I have code which compiles nicely on gentoo 4.14.83, with both gcc-7.3.0 and gcc-8.2.0.
On CentOS 7 (CentOS Linux release 7.6.1810 (Core)), however, the linker of g++-7.3.1 says:
/home/jody/progs/multi_spc_QHG3/kernel/Geography.cpp:68: undefined reference to `__cxa_throw_bad_array_new_length'
/home/jody/progs/multi_spc_QHG3/kernel/Geography.cpp:69: undefined reference to `__cxa_throw_bad_array_new_length'
/home/jody/progs/multi_spc_QHG3/kernel/Geography.cpp:70: undefined reference to `__cxa_throw_bad_array_new_length'
/home/jody/progs/multi_spc_QHG3/kernel/Geography.cpp:71: undefined reference to `__cxa_throw_bad_array_new_length'
The referenced lines in Geography.cpp have simple new statements:
m_adLatitude = new geonumber[m_iNumCells];
m_adLongitude = new geonumber[m_iNumCells];
m_adAltitude = new geonumber[m_iNumCells];
m_adDistances = new geonumber[m_iNumCells*m_iMaxNeighbors];
(the type geonumber is actually double, m_iNumCells and m_iMaxNeighbors have type int)
Because i need g++ version 7, i use the compiler from devtoolset-7-gcc.x86_64.
Some of the posts i found stated that this error is caused by missing libstdc++, but this is not the case here.
What causes this error, and how can it be fixed?
I have a "CMakified" version of CryptoPP and I am using CMake-GUI to create a MakeFile which ming-make could process as shown in the image below.
The "MakeFile" creation was successful but when I executed mingw32-make.exe I got below errors at the very end.

I tried adding LDLIBS += -lws2_32 to the very end of the make file but this didn't help. I guess these errors are because the target link libraries are not mentioned in the make file but I am not sure how to do this.
CMakeLists.txt should call
target_link_libraries(cryptopp ws2_32)
after command ADD_LIBRARY to resolve undefined references.
After following Kieth's comments above I figured out that neither LIBS nor LDLIBS are honoured by CMAKE. The variable to use is CXX_STANDARD_LIBRARIES. I did the below change in the CMAKE Advanced options:
I added -lws2_32 at the very end and then generated the "MakeFile" .
This solved the issue.
