QT5.15.2 and qilinv10 and arm64

[quan-wei-jun]

@jsulm Hello, thank you very much for answering my question. Now I will tell you my steps

Step 1:

Unzip source file: sudo tar - xvf qt everywhere src-5.15.2. tar

Step 2: Install the basic environment:

Sudo apt-get install libxcb-xinerama0-dev

Sudo apt-get install '^ libxcb. * - dev' libx11-xcb dev libglu1 mesa dev libxender dev libxi dev libxkbcommon dev libxkbcommon x11 devsudo apt-get install build essential perl Python git

Sudo apt-get install flex bison gperf libicu dev libxslt dev ruby

Sudo apt get install libssl dev libxcursor dev libxcomposite dev libxdamage dev libxrandr dev libdbus-1 dev libfontconfig1 dev libcap dev libxtst dev libpulse dev libudev dev libpci dev libnss3 dev libasound2 dev libxss dev libegl1 mesa dev gperf bioson

Sudo apt get install libasound2 dev libgstreamer0.10 dev libgstreamer plugins base 0.10 dev

Sudo apt install libclang-6.0 dev llvm-6.0

Sudo apt-get install clang

Sudo apt-get install clang-8

Cd qt everywhere src-5.15.2/qtwebengine/src/3rdparty/ninja

./configure. py -- bootstrap

Ninja -- version

These are all okay

Step 3:

Modify the extracted file qt.pro and add CONFIG+=c++11

Step 4

Configure command

./configure - prefix/usr/local/Qt 5.15.2- release - open source - make examples - make tests - platform Linux lang - check all
/home/Qt_source/qt-everywhere-src-5.15.2$ ./configure -prefix /usr/local/Qt-5.15.2 -release -opensource -nomake examples -nomake tests -platform linux-clang -recheck-all

• cd qtbase
• /home/Qt_source/qt-everywhere-src-5.15.2/qtbase/configure -top-level -prefix /usr/local/Qt-5.15.2 -release -opensource -nomake examples -nomake tests -platform linux-clang -recheck-all
  Creating qmake...
  .Done.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/usr/local/Qt-5.15.2'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

step6：
make -j 8

Then, which error will appear that I want to solve? Can you take a look at which step was wrong? Thank you very much

[jsulm]

@quan-wei-jun Are you building Qt?!

[quan-wei-jun]

@jsulm
yes，I haven't been successful in building it for a long time. Can you help me

@jsulm Can you help me?

@quan-wei-jun said in QT5.15.2 and qilinv10 and arm64:

Build type: linux-clang (arm64, CPU features: neon)
Compiler: clang 4.0.0

It looks like you're using Clang and not GCC as compiler.
"-platform linux-clang" - is wrong I would say.

[quan-wei-jun]

@jsulm Do you know how to modify it

[quan-wei-jun]

@jsulm I am a novice and have many misunderstandings. Thank you very much for answering my question

[jsulm]

@quan-wei-jun said in QT5.15.2 and qilinv10 and arm64:

Do you know how to modify it

Instead of -platform linux-clang pass a parameter to configure matching your target platform

@jsulm
我认为应该linux-clang编译器是可以的,为什么我会这样想--因为它已经可以make了，只不过是make之中出现的错误是不是应该考虑换一个linux-clang.但是又有一个问题就是如何选择linux-clang的版本问题了

I think the Linux lang compiler is possible, why do I think so? Because it can already be made, but it's just an error in making. Should we consider switching to a different Linux lang? However, another issue is how to choose the version of Linux lan
