Cross-Compile Qt 6.10 para sa RaspiOS Trixie

Pagpapakilala

Sa isang nakaraang mga blogpost Install Raspberry Pi OS sa Raspberry Compute Module 4 isinulat ko ang tungkol sa pag-install ng Raspbian sa Raspberry Compute Module at pag-setup ng cross compilation para sa QtCreator sa Ubuntu 20.

Ang blogpost na ito ay isang pag-update sa - sa oras na ito - pinakabagong bersyon 6.10 ng Qt, RaspiOS Trixie at Ubuntu 24.04 LTS.

Sa kasong ito, gumamit ako ng isang virtual machine, na nilikha gamit ang UTM sa isang MacBook Pro M1.

Mga kinakailangan

Ang mga sumusunod na software at software ay ginagamit

Raspberry Pi Compute Module 5* MacBook Pro M1 na may naka-install na UTM
Ubuntu 24.0.4 LTS, arm64
Qt bersyon 6.10.1
QtCreator 18

Ang pag-install at pag-setup ng Compute Module 5 at ng Ubuntu sa UTM ay hindi nilalaman ng blogpost na ito, dahil maraming mga tuturial na matatagpuan sa internet.

I-setup ang Raspberry CM5

Flash image sa eMMC gamit ang Raspberry Pi Imager
Sundin ang pag-install at huwag kalimutan ang setting para sa remote connect (ssh)
Kumonekta sa RPi gamit ang ssh -> sa aking kaso sa IP address 192.168.2.194 at user pi -> mula sa iyong host ng Ubuntu

ssh [email protected]

I-install ang kinakailangang software:

Gumawa ng isang folder para sa pag-install ng Qt 6:

sudo mkdir /usr/local/qt6

Idagdag ang sumusunod na piraso ng code sa dulo ng ~/.bashrc at i-update ang mga pagbabago:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/qt6/lib/
source ~/.bashrc

I-setup ang Ubuntu 24.04 LTS

I-update ang pinakabagong mga bersyon ng mga pakete ng software:

sudo apt update
sudo apt upgrade

I-install ang mga sumusunod na pakete:

sudo apt-get install make cmake build-essential libclang-dev clang ninja-build gcc git bison python3 gperf pkg-config libfontconfig1-dev libfreetype6-dev libx11-dev libx11-xcb-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-util-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev libatspi2.0-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev python3-html5lib libxcb-dri3-dev libxkbfile-dev libxshmfence-dev libxrandr-dev libxcursor-dev libxcomposite-dev libdrm-dev libwayland-dev

Mayroong dalawang mga pagpipilian upang bumuo ng Qt6. Mayroong isang "single" (https://download.qt.io/official_releases/qt/6.10/6.10.1/single/qt-everywhere-src-6.10.1.tar.xz) bersyon upang i-download, na naglalaman ng qtbase at lahat ng mga submodule. Ito ay napakabigat na bagay at nangangailangan ng maraming kapangyarihan at oras upang mai-compile ito.

Ang aking rekomendasyon ay, upang i-compile qtbase bilang batayan at pagkatapos ay i-compile lamang ang bawat submodule na kailangan mo nang hiwalay.

Gumawa ng mga folder para sa sysroot at qt6. Lumilikha ako ng mga folder na ito sa aking direktoryo ng Mga Dokumento / Cross-Compile / raspi-os-trixie.

mkdir ~/Documents/Qt-Cross-Compile ~/Documents/Qt-Cross-Compile/raspi-os-trixie
cd ~/Documents/Qt-Cross-Compile/raspi-os-trixie
mkdir rpi-sysroot rpi-sysroot/usr rpi-sysroot/opt
mkdir qt6 qt6/host qt6/pi qt6/host-build qt6/pi-build qt6/src

I-download ang QtBase source code

cd ~/Documents/Qt-Cross-Compile/raspi-os-trixie/qt6/src
wget https://download.qt.io/official_releases/qt/6.10/6.10.1/submodules/qtbase-everywhere-src-6.10.1.tar.xz
tar xf qtbase-everywhere-src-6.10.1.tar.xz

palitan ang pangalan ng qtbase-everywhere-src-6.10.1 sa qtbase, dahil ang mga qttranslations ay hindi maaaring gumana sa qtbase-everywhere-src-6.10.1

mv qtbase-everywhere-src-6.10.1 qtbase

Bumuo ng Qt6 para sa host

cd ~/Documents/Qt-Cross-Compile/raspi-os-trixie/qt6/host-build

cmake ../src/qtbase/ -GNinja -DCMAKE_BUILD_TYPE=Release -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=$HOME/Documents/Qt-Cross-Compile/raspi-os-trixie/qt6/host

cmake --build . --parallel 8
cmake --install .

Ang mga binaries ay nasa ~ / Documents / Qt-Cross-Compile / raspi-os-trixie / qt6 / host

Bumuo ng Qt6 para sa RPI

Kopyahin at i-paste ang ilang mga folder mula sa rpi gamit ang rsync sa pamamagitan ng SSH.

cd ~/Documents/Qt-Cross-Compile/raspi-os-trixie
rsync -avzS --rsync-path="rsync" --delete [email protected]:/lib/* ~/Documents/Qt-Cross-Compile/raspi-os-trixie/rpi-sysroot/lib
rsync -avzS --rsync-path="rsync" --delete [email protected]:/usr/include/* ~/Documents/Qt-Cross-Compile/raspi-os-trixie/rpi-sysroot/usr/include
