How to get GCC for Qt 5.9.5?

SGaist

C:\Qt\5.9.5\mingw53_32

This means that you have a 32 bit Qt version built with MinGW5.3. The subfolder name indicates which compiler was used as well as the architecture of the build.

The compiler is located under Tools.

@SGaist I see, I think the mingw53_32 is missed something. So I want to get mingw 5.3.0 separately. is there MinGW archive something for each version of mingw? I could not find it.

@hslee_6560 How did you install Qt? The Qt installer and Qt maintenance tool both give you the possibility to install MinGW.

Is this problem solved? I've met the same problem. My gstreamer android version:gstreamer-1.0-android-universal-1.18.6. However windows version work perfect.

Not really. Problem in this thread was witn MinGW build on Windows.
You have a problem with Android.
Please explain exactly what you're doing and what the problem you have.

GStreamer on Android: https://doc.qt.io/qt-5/platform-notes-gstreamer-on-android.html

I build a qgc project on the windows with qt version 5.15.2 , Android setting:jdk-11,sdk version 9.0 and ndk-verison 21.3.6528147. Before importing gstreamer, it work well. After downloading gstreamer-1.0-android-universal-1.18.6, and change the GST_ROOT at VideoReceiver.pri. I run the program in the abi of arm64-v8a, I get the following error.

:/MinGW/lib/gcc/mingw32/6.3.0/include/c++/mingw32/bits/c++config.:223: Parse error at "__cxx11"

Should I modify the document of gradle?

@Jleon I don't understand what you are doing: if you're building for Android then why there is mingw32 stuff in the build log?!
And you always should post the very first error.

Jleon

Alright the first error is AVD start error, but I thought it's irrelevant. Well my setting is the belowing:

else : android-clang {
        CONFIG += AndroidBuild MobileBuild
        DEFINES += __android__
        DEFINES += __STDC_LIMIT_MACROS
        DEFINES += QGC_ENABLE_BLUETOOTH
        DEFINES += QGC_GST_TAISYNC_ENABLED
        DEFINES += QGC_GST_MICROHARD_ENABLED
        QMAKE_CXXFLAGS_WARN_ON += -Werror \
            -Wno-unused-parameter \             # gst_plugins-good has these errors
            -Wno-implicit-fallthrough \         # gst_plugins-good has these errors
            -Wno-unused-command-line-argument \ # from somewhere in Qt generated build files
            -Wno-parentheses-equality           # android gstreamer header files
        }

I was not sure why did mingw32 in there.

Jleon

I found the answer.
Go to the file:C:\MinGW\lib\gcc\mingw32\6.3.0\include\c++\mingw32\bits\c++config.h
And modify the code

#define _GLIBCXX_USE_CXX11_ABI 0

from 1 to 0
But I don't think it is the best solution, it might destroy some structure.
What flags should I use in .pro to make sure the file got to know it defines to zero?

@Jleon I still fail to understand what MinGW stuff has to do with Android build.
For Android the Clang compiler from NDK is used.
It seems that your environment is broken.
