Reference not defined in compiling an executable for windows x86

Question

I’m building a scaffold project for cross-Compile on c/c++ for Windows, Linux, Mac, Ios and Android. When I compile the project for Windows x86 and I have a very strange error, but the same code successfully compiles to Windows x64. When I removed the use of vector I can compile for Windows x86. I wonder if any library is missing for link?

Following link from the repository. https://github.com/Jhonnycpp/Jia

I am using these packages in Ubuntu build-Essential, gcc-multilib, g++-multilib, Clang-9, cmake, mingw-W64.

//main.cpp
#include <iostream>
#include <vector>

using namespace std;

int main()
{
    vector<int> t;
    t.push_back(1);
    t.push_back(2);
    t.push_back(2);

    for(int it : t)
        cout << it << endl;

    cout << "Hello word" << endl << endl;
}

For some reason Clang is not finding the symbols used to unwind the stack (unwinding stack), which is probably in a specific library. Because of this, if you add the flag -fno-exceptions the error adds up:

$ git diff
diff --git a/CMakeLists.txt b/CMakeLists.txt
index c6eb183..f161adc 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -24,7 +24,7 @@ set(CMAKE_BINARY_DIR ${WORKSPACE}/build)

 string(TOUPPER ${OS} ${OS})

-SET(CUSTOM_BUILD_PARAMS "")
+SET(CUSTOM_BUILD_PARAMS "-fno-exceptions")
 SET(CUSTOM_LINKER_PARAMS "")

 if(${OS} STREQUAL "WINDOWS")
$ 

Of course, by doing this you can no longer use exceptions.
