Raspberry Compute-modul 5

Krysskompilere Qt 6.10 for RaspiOS Trixie

Innledning

I et tidligere blogginnlegg Install Raspberry Pi OS on the Raspberry Compute Module 4 skrev jeg om installasjonen av Raspbian på Raspberry Compute Module og oppsett av krysskompilering for QtCreator på Ubuntu 20.

Dette blogginnlegget er en oppdatering til den - på dette tidspunktet - nyeste versjonen 6.10 av Qt, RaspiOS Trixie og Ubuntu 24.04 LTS.

I dette tilfellet brukte jeg en virtuell maskin, opprettet med UTM på en MacBook Pro M1.

Krav

Følgende hard- og programvare brukes
  • Raspberry Pi Compute Module 5
  • MacBook Pro M1 med UTM installert
  • Ubuntu 24.0.4 LTS, arm64
  • Qt versjon 6.10.1
  • QtCreator 18

Installasjon og oppsett av Compute Module 5 og av Ubuntu i UTM er ikke innholdet i denne bloggposten, da det finnes mange veiledninger på internett.

Oppsett Raspberry CM5

  • Flash-bilde til eMMC med Raspberry Pi Imager
  • Følg installasjonen og ikke glem innstillingen for ekstern tilkobling (ssh)
  • Koble til RPi med ssh -> i mitt tilfelle til IP-adresse 192.168.2.194 og bruker pi -> fra din Ubuntu-vert
ssh [email protected]
  • Installer nødvendig programvare:
sudo apt-get install libboost-all-dev libudev-dev libinput-dev libts-dev libmtdev-dev libjpeg-dev libfontconfig1-dev libssl-dev libdbus-1-dev libglib2.0-dev libxkbcommon-dev libegl1-mesa-dev libgbm-dev libgles2-mesa-dev mesa-common-dev libasound2-dev libpulse-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev  gstreamer1.0-alsa libvpx-dev libsrtp2-dev libsnappy-dev libnss3-dev "^libxcb.*" flex bison libxslt-dev ruby gperf libbz2-dev libcups2-dev libatkmm-1.6-dev libxi6 libxcomposite1 libfreetype6-dev libicu-dev libsqlite3-dev libxslt1-dev

  • Lag en mappe for Qt 6-installasjon:
sudo mkdir /usr/local/qt6
  • Legg til følgende stykke kode på slutten av ~/.bashrc og oppdater endringene:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/qt6/lib/
source ~/.bashrc

Installasjon av Ubuntu 24.04 LTS

  • Oppdater til de nyeste versjonene av programvarepakkene:
sudo apt update
sudo apt upgrade
  • Installer følgende pakker:
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

Bygge Qt6

Det finnes to muligheter for å bygge Qt6. Du kan laste ned en "single" (https://download.qt.io/official_releases/qt/6.10/6.10.1/single/qt-everywhere-src-6.10.1.tar.xz) -versjon, som inneholder qtbase og alle undermoduler. Dette er veldig tunge greier og trenger mye kraft og tid for å kompilere det.

Min anbefaling er å kompilere qtbase som basis og deretter kompilere hver undermodul du trenger separat.

  • Lag mapper for sysroot og qt6. Jeg oppretter disse mappene i Documents/Cross-Compile/raspi-os-trixie-katalogen.
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
  • Last ned QtBase-kildekoden
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
  • gi nytt navn til qtbase-everywhere-src-6.10.1 til qtbase, da qttranslations ikke kan fungere med qtbase-everywhere-src-6.10.1
mv qtbase-everywhere-src-6.10.1 qtbase

Bygg Qt6 for 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 .

Binærfiler vil ligge i ~/Documents/Qt-Cross-Compile/raspi-os-trixie/qt6/host

Bygg Qt6 for rpi

Kopier og lim inn noen mapper fra rpi ved hjelp av rsync via 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
