Raspberry Compute-modul 5

Krydskompilér Qt 6.10 til RaspiOS Trixie

Introduktion

I et tidligere blogindlæg Install Raspberry Pi OS on the Raspberry Compute Module 4 skrev jeg om installation af Raspbian på Raspberry Compute Module og opsætning af krydskompilering til QtCreator på Ubuntu 20.

Dette blogindlæg er en opdatering til den - på nuværende tidspunkt - nyeste version 6.10 af Qt, RaspiOS Trixie og Ubuntu 24.04 LTS.

I dette tilfælde brugte jeg en virtuel maskine, oprettet med UTM på en MacBook Pro M1.

Kravene

Følgende hard- og software anvendes
  • Raspberry Pi Compute Module 5
  • MacBook Pro M1 med UTM installeret
  • Ubuntu 24.0.4 LTS, arm64
  • Qt version 6.10.1
  • QtCreator 18

Installationen og opsætningen af Compute Module 5 og af Ubuntu i UTM er ikke indholdet af dette blogindlæg, da der er mange vejledninger at finde på internettet.

Opsætning af Raspberry CM5

  • Flash-billede til eMMC med Raspberry Pi Imager
  • Følg installationen, og glem ikke indstillingen for fjernforbindelse (ssh)
  • Opret forbindelse til RPi'en med ssh -> i mit tilfælde til IP-adressen 192.168.2.194 og brugeren pi -> fra din Ubuntu-vært
ssh [email protected]
  • Installer den nødvendige software:
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
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libx11-dev freetds-dev libsqlite3-dev libpq-dev libiodbc2-dev firebird-dev libxext-dev libxcb1 libxcb1-dev libx11-xcb1 libx11-xcb-dev libxcb-keysyms1 libxcb-keysyms1-dev libxcb-image0 libxcb-image0-dev libxcb-shm0 libxcb-shm0-dev libxcb-icccm4 libxcb-icccm4-dev libxcb-sync1 libxcb-sync-dev libxcb-render-util0 libxcb-render-util0-dev libxcb-xfixes0-dev libxrender-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-glx0-dev libxi-dev libdrm-dev libxcb-xinerama0 libxcb-xinerama0-dev libatspi2.0-dev libxcursor-dev libxcomposite-dev libxdamage-dev libxss-dev libxtst-dev libpci-dev libcap-dev libxrandr-dev libdirectfb-dev libaudio-dev libxkbcommon-x11-dev gdbserver
  • Lav en mappe til Qt 6-installationen:
sudo mkdir /usr/local/qt6
  • Tilføj følgende stykke kode til slutningen af ~/.bashrc, og opdater ændringerne:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/qt6/lib/
source ~/.bashrc

Opsætning af Ubuntu 24.04 LTS

  • Opdater til de nyeste versioner af softwarepakkerne:
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

Opbygning af Qt6

Der er to muligheder for at bygge Qt6. Der kan downloades en "single" (https://download.qt.io/official_releases/qt/6.10/6.10.1/single/qt-everywhere-src-6.10.1.tar.xz) -version, som indeholder qtbase og alle undermoduler. Det er meget tunge ting og kræver meget kraft og tid at kompilere.

Min anbefaling er at kompilere qtbase som basis og derefter kun kompilere hvert undermodul, du har brug for, separat.

  • Lav mapper til sysroot og qt6. Jeg opretter disse mapper i min Documents/Cross-Compile/raspi-os-trixie mappe.
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
  • Download kildekoden til QtBase
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
  • omdøb 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

Byg Qt6 til værten

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 være i ~/Documents/Qt-Cross-Compile/raspi-os-trixie/qt6/host

Byg Qt6 til rpi

Kopier og indsæt et par mapper fra rpi ved hjælp af 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
