Modul Komputasi Raspberry 5

Kompilasi Silang Qt 6.10 untuk RaspiOS Trixie

Pendahuluan

Dalam postingan blog sebelumnya Install Raspberry Pi OS on the Raspberry Compute Module 4 Saya menulis tentang instalasi Raspbian di Raspberry Compute Module dan pengaturan kompilasi silang untuk QtCreator di Ubuntu 20.

Blogpost ini adalah update untuk - pada saat ini - versi 6.10 terbaru dari Qt, RaspiOS Trixie dan Ubuntu 24.04 LTS.

Dalam kasus ini, saya menggunakan mesin virtual, yang dibuat dengan UTM pada MacBook Pro M1.

Persyaratan

Perangkat keras dan perangkat lunak berikut ini digunakan
  • Raspberry Pi Compute Module 5
  • MacBook Pro M1 dengan UTM terinstal
  • Ubuntu 24.0.4 LTS, arm64
  • Qt versi 6.10.1
  • QtCreator 18

Instalasi dan pengaturan Compute Module 5 dan Ubuntu di UTM tidak termasuk dalam artikel blog ini, karena ada banyak tuturial yang dapat ditemukan di internet.

Menyiapkan Raspberry CM5

  • Mem-flash gambar ke eMMC dengan Raspberry Pi Imager
  • Ikuti instalasi dan jangan lupa pengaturan untuk sambungan jarak jauh (ssh)
  • Sambungkan ke RPi dengan ssh -> dalam kasus saya ke alamat IP 192.168.2.194 dan user pi -> dari host Ubuntu Anda
ssh [email protected]
  • Instal perangkat lunak yang dibutuhkan:

  • Buatlah folder untuk instalasi Qt 6:
sudo mkdir /usr/local/qt6
  • Tambahkan potongan kode berikut ini ke akhir ~/.bashrc dan perbarui perubahannya:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/qt6/lib/
source ~/.bashrc

Pengaturan Ubuntu 24.04 LTS

  • Perbarui ke versi terbaru dari paket perangkat lunak:
sudo apt update
sudo apt upgrade
  • Instal paket berikut ini:
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

Membangun Qt6

Ada dua kemungkinan untuk membangun Qt6. Ada versi "single" (https://download.qt.io/official_releases/qt/6.10/6.10.1/single/qt-everywhere-src-6.10.1.tar.xz) yang dapat diunduh, yang berisi qtbase dan semua submodul. Ini adalah hal yang sangat berat dan membutuhkan banyak tenaga dan waktu untuk mengkompilasinya.

Rekomendasi saya adalah, kompilasi qtbase sebagai dasar dan setelah itu kompilasi setiap submodul yang Anda perlukan secara terpisah.

  • Buatlah folder untuk sysroot dan qt6. Saya membuat folder ini di direktori Documents/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
  • Unduh kode sumber 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
  • ganti nama qtbase-everywhere-src-6.10.1 menjadi qtbase, karena qttranslations tidak dapat bekerja dengan qtbase-everywhere-src-6.10.1
mv qtbase-everywhere-src-6.10.1 qtbase

Membangun Qt6 untuk 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 .

Binari akan berada di ~/Documents/Qt-Cross-Compile/raspi-os-trixie/qt6/host

Membangun Qt6 untuk rpi

Salin dan tempelkan beberapa folder dari rpi menggunakan rsync melalui 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
rsync -avzS --rsync-path="rsync" --delete [email protected]:/usr/lib/* ~/Documents/Qt-Cross-Compile/raspi-os-trixie/rpi-sysroot/usr/lib
rsync -avzS --rsync-path="rsync" --delete [email protected]:/opt/vc ~/Documents/Qt-Cross-Compile/raspi-os-trixie/rpi-sysroot/opt/vc
  • Buat sebuah berkas bernama toolchain.cmake di ~/Documents/Qt-Cross-Compile/raspi-os-trixie.
    Anda perlu menyesuaikan baris "set(TARGET_SYSROOT ~/Documents/Qt-Cross-Compile/raspi-os-trixie/rpi-sysroot)" ke lingkungan Anda.
