Undef. ref. __emutls on Qt 5.15.1 static Windows

MikePooh

Hi all!

I am building static app using Qt 5.15.1 + GStreamer 1.18.1 on Windows 10. For that purposes Qt 5.15.1 static has been built from source using Mingw 8.1.0 64bit with following configure:

configure -static -platform win32-g++ -prefix "D:\Qt_Win\5.15.1\static_2\mingw81_64" -release -opensource -confirm-license -nomake examples -nomake tests -nomake tools -opengl desktop -no-angle -qt-sqlite -make libs -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype

When I am trying to build my application with that Static Qt, I am getting follwong linker errors:

D:\Qt_Win\5.15.1\static_2\mingw81_64\plugins\platforms\libqwindows.a(qwindowsservices.o):qwindowsservices.cpp:(.rdata$.refptr.__emutls_v._ZSt11__once_call[.refptr.__emutls_v._ZSt11__once_call]+0x0): undefined reference to `__emutls_v._ZSt11__once_call'
D:\Qt_Win\5.15.1\static_2\mingw81_64\plugins\platforms\libqwindows.a(qwindowsservices.o):qwindowsservices.cpp:(.rdata$.refptr.__emutls_v._ZSt15__once_callable[.refptr.__emutls_v._ZSt15__once_callable]+0x0): undefined reference to `__emutls_v._ZSt15__once_callable'
collect2.exe: error: ld returned 1 exit status

Part of important qmake conf for the project

TEMPLATE = app
QT += widgets network multimedia xml
QMAKE_CXXFLAGS += -O2 -Wall -Wextra -Werror=return-type -Wno-parentheses -Wno-switch -fdiagnostics-color=always -fno-diagnostics-show-caret -std=c++11 -pthread

win32 {
    LIBS += -LD:\gstreamer\1.0\mingw_x86_64\lib\ -lgstreamer-1.0.dll -lgobject-2.0.dll -lglib-2.0.dll -lgstvideo-1.0.dll
    INCLUDEPATH += D:\gstreamer\1.0\mingw_x86_64\include\gstreamer-1.0 D:\gstreamer\1.0\mingw_x86_64\include\glib-2.0 D:\gstreamer\1.0\mingw_x86_64\lib\glib-2.0\include
    QMAKE_LFLAGS += -static -static-libgcc -static-libstdc++
    DEFINES += STATIC
}

Some other of my applications builds fine with that Qt5.15.1 Static without any problems as well as current application builds fine with officialy downloaded Qt 5.15.1 (Dynamic).

Will be appreciate for any help.
