Using compilers other than MinGW

[jsulm]

@tomy "I don't know what it is" - well, it is Qt built using Clang compiler.
You have a Kit for Android + Clang, you can use it to build for Android.
If you want to see how to do so build first in QtCreator and check the "Compile Output" tab to see how QtCreator builds the project.

I tested a number of QtQuick apps to build for Android, but for all I get the error below!

C:\Qt\5.14.0\android\include\QtCore\qglobal.h:45: error: 'type_traits' file not found
#  include <type_traits>
           ^~~~~~~~~~~~~

The problem was with NDK. A higher version of NDK solved the issue. (For those who might come across the issue afterwards too)

I built and created the .apk file of a project called QML_test_1 using Qt Creator. The Output Window shows hundreds of lines! How to pinpoint the expressions to build the project the same way as the prior stage, this time with Clang, please?

@tomy said in Using compilers other than MinGW:

this time with Clang, please?

Please take a closer look at the output you get:

D:\Qt_Stuff\android-ndk-r21/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++ -c -target armv7a-linux-an

Do you see clang++ ?
The android Kit already uses Clang to compile.

[tomy]

@jsulm

The problem is that I'm not experienced in it.
Anyways, yes, I see the above section which is part of a very long line.

Should I use this method?

• Going to the "Build" folder using CMD
• Typing D:\Qt_Stuff\android-ndk-r21/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++ -c -target armv7a-linux-androideabi21 followed by the path to the project's directory

[jsulm]

@tomy said in Using compilers other than MinGW:

Should I use this method?

Why do you want to do this? This line calls the compiler to compile a source code file. There is usually no need to do it manually, especially in bigger projects. This is how a QMake based project is usually build:

qmake
make
make install

As you can see there is no manual compiler call . Make calls compiler for you.
Can you please explain what you're trying to achieve?

[tomy]

@jsulm

I think I said that in our prior posts. I'm aiming at building projects using GCC and Clang compilers from command line instead of the hammer button on the IDE (ctrl+B). For the GCC compiler, we made it above and built the project.
For Clang, you said it's similar. So I thought of that set of instructions.

For an empty folder called "BuildApk" on desktop to be used for building: C:\Users\ME\Desktop\BuildApk
and the project's directory on the path: D:\Projects\QML\QML_test_1\QML_test_1
what expressions do I need to use to build the project QML_test_1 using Clang?

[jsulm]

@tomy If you want to build Qt apps with CLang you need Qt build with that compiler (and of cource CLang). Then you do it as usual: qmake, make.
For Android this is already the case as Android NDK uses CLang and Qt for Android is built using CLang from Android NDK.
For which other platform do you want to use CLang?

[tomy]

@jsulm

I just want to build a project using Clang manually. And since the Android kit has that compiler on my Qt, so I chose a QML project.

So I think I must go this way:

• C:\Users\ME\Desktop\BuildApk>C:\Qt\5.14.0\android\bin\qmake.exe D:\Projects\QML\QML_test_1\QML_test_1

*the make file but what is the name of that and on what address on Qt!?

I guess I also need to setup the environment. But is the name of the file for Clang qtenv2.bat as well?

[jsulm]

@tomy said in Using compilers other than MinGW:

the make file but what is the name of that and on what address on Qt!?

I don't understand this. Do you mean the name and location of the make file?
Makefile is created in the directory from which you call qmake and it is called Makefile.

[tomy]

@jsulm

No I meant the make and qmake files.
Please look at your previous set:

• 1- Open CMD
• 2- Create a build directory somewhere
• 3- Change to that directory
• 4- PATH_TO_MINGW_QT/qmake.exe PATH_TO_YOUR_PROJECT_DIRECTORY
• 5- PATH_TO_QT_Tools/mingw730_64/bin/mingww32-make.exe

I think number 4 should change to this:

• 4- PATH_TO_ANDROID/qmake.exe PATH_TO_YOUR_PROJECT_DIRECTORY

I found the qmake.exe file here: C:\Qt\5.14.0\android\bin\qmake.exe

Agree up to here?
If so, then we need to look up the make.exe file but this time not inside the mingw730_64 folder. Right?

[jsulm]

@tomy said in Using compilers other than MinGW:

It's right there in the build log you posted before:

20:08:05: Starting: "D:\Qt_Stuff\android-ndk-r21\prebuilt\windows-x86_64\bin\make.exe"

[tomy]

@jsulm

I ran the following and got the error for the environment. I'm sure the file for this is not that qtenv2.bat we used for GCC.

C:\Users\ME\Desktop\BuildApk>C:\Qt\5.14.0\android\bin\qmake.exe D:\Projects\QML\QML_test_1\QML_test_1
Project ERROR: You need to set the ANDROID_NDK_ROOT environment variable to point to your Android NDK.

Error processing project file: D:\Projects\QML\QML_test_1\QML_test_1\QML_test_1.pro

Should I firstly run this line on CMD?
C:\Qt\5.14.0\android\mkspecs\android-clang\qmake.conf

[jsulm]

@tomy said in Using compilers other than MinGW:

C:\Qt\5.14.0\android\mkspecs\android-clang\qmake.conf

This is a config file, nothing you can run.
The error message tells you what is missing: "You need to set the ANDROID_NDK_ROOT environment variable to point to your Android NDK".
Check the Build settings for that Kit in QtCreator (left side "Projects/Build/Build Environment") and look there for ANDROID_NDK_ROOT variable there. Then, before running qmake, set ANDROID_NDK_ROOT in the same way it is set in Build settings.

[tomy]

@jsulm

Check the Build settings for that Kit in QtCreator (left side "Projects/Build/Build Environment") and look there for ANDROID_NDK_ROOT variable there.

I found it and its root there is: D:\Qt_Stuff\android-ndk-r21

Then, before running qmake, set ANDROID_NDK_ROOT in the same way it is set in Build settings.

I sat that this way, on Windows Environment:

Then ran the CMD command:

C:\Users\ME\Desktop\BuildApk>C:\Qt\5.14.0\android\bin\qmake.exe D:\Projects\QML\QML_test_1\QML_test_1
Info: creating stash file C:\Users\ME\Desktop\BuildApk\.qmake.stash

C:\Users\ME\Desktop\BuildApk>

Then a number of files were created in the folder:

But still there isn't any .apk file there!

[tomy]

Sorry, I forgot to run the last command which is the path to make.exe:
D:\Qt_Stuff\android-ndk-r21\prebuilt\windows-x86_64\bin\make.exe

After this, a few more files, including .exe files, were added to the BuildApk folder (which is expected as we're on the windows-x86_64 path). But still no .apk file.

When we built the project using Gcc for Windows, we obtained the executable file. So we must obtain the .apk file for Android when we build the project using Clang for Android kit. Not right?

Where have I gone wrong and how to built the project completely so that we also have the apk file, please?

[mrjj]

@tomy
Hi
Normally the APk is build by Creator. When you compile in the commandline, you have to do this step manually.
Details here.
https://doc.qt.io/qt-5/deployment-android.html

I think when running androiddeployqt its will make the APK file but i cant tell what parameters to use.
