Uvod

U prethodnoj seriji postova na blogu

Pisao sam o instalaciji Raspbiana na Raspberry Compute Module i postavljanju unakrsne kompilacije za QtCreator na Ubuntu 20.

Ovaj blog post je ažuriranje - u ovom trenutku - najnovije verzije 6.8 Qt, raspi OS Bookworm i Ubuntu 22.04 LTS.

Preduvjeti

Koristio sam sljedeći hardver i softver:

  • Raspberry Pi 4
  • raspi OS Bookworm, bez preporučenog softvera
  • Ubuntu 22.04 LTS
  • Qt 6.8
  • QtCreator 14.02

Bilješke

Ako imate prijenosno ili stolno računalo s dovoljno RAM-a i CPU jezgri, možete napraviti unakrsnu kompilaciju u virtualnom stroju. Ali stekao sam iskustvo da je izvorno računalo puno brže i proizvodi manje pogrešaka.

Pogledajte putanje datoteka i ip adrese u mojim primjerima koda i prilagodite ih svojim potrebama.

Postavite Raspberry Pi

  • Preuzmite raspiOS s https://www.raspberrypi.com/software/operating-systems
  • 2024-07-04-raspios-bookworm-arm64.img.xz: 64-bitni s Raspberry Pi OS-om sa stolnim računalom (ne s preporučenim softverom)
  • Flash slika na SD karticu s Balena Etcher
  • Slijedite instalaciju i ne zaboravite postavku za daljinsko povezivanje (ssh)
  • Povežite se s RPi sa ssh -> u mom slučaju na IP adresu 192.168.2.167 i korisničkog pi -> s vašeg Ubuntu hosta
ssh [email protected]
  • Instalirajte potreban softver:

  • Napravite mapu za instalaciju Qt 6:
sudo mkdir /usr/local/qt6
  • Otkrijte verzije gcc, ld i ldd. Izvorni kod iste verzije treba preuzeti za kasniju izradu unakrsnog kompajlera.

  • Dodajte sljedeći dio koda na kraj ~/.bashrc i ažurirajte promjene:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/qt6/lib/
source ~/.bashrc

Postavite Ubuntu 22.04 LTS

  • Ažurirajte na najnovije verzije softverskih paketa:
sudo apt update
sudo apt upgrade
  • Instalirajte sljedeće pakete:
sudo apt-get install make build-essential libclang-dev 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 build-essential gawk git texinfo bison file wget libssl-dev gdbserver gdb-multiarch libxcb-cursor-dev

Izgradite najnoviju verziju cmake iz izvora:

cd ~

tar -xzvf cmake-3.30.5.tar.gz
cd cmake-3.30.5
./bootstrap
make -j$(nproc)
sudo make install
# Update PATH Environment Variable
which cmake
/usr/local/bin/cmake
export PATH=/usr/local/bin/cmake:$PATH
source ~/.bashrc
cmake --version

Izradite gcc kao unakrsni kompajler

Preuzmite potreban izvorni kod. Sljedeće naredbe trebali biste izmijeniti prema svojim potrebama. Za vrijeme kada napravim ovu stranicu, to su:

  • GCC 12.2.0
  • Binutils 2.40 (LD verzija)
  • GLIBC 2.36 (LDD verzija)
cd ~
mkdir gcc_all && cd gcc_all
wget https://ftpmirror.gnu.org/binutils/binutils-2.40.tar.bz2
wget https://ftpmirror.gnu.org/glibc/glibc-2.36.tar.bz2
wget https://ftpmirror.gnu.org/gcc/gcc-12.2.0/gcc-12.2.0.tar.gz
git clone --depth=1 https://github.com/raspberrypi/linux

tar xf glibc-2.36.tar.bz2
tar xf gcc-12.2.0.tar.gz
rm *.tar.*
cd gcc-12.2.0
contrib/download_prerequisites
  • Napravite mapu za instalaciju kompajlera.
sudo mkdir -p /opt/cross-pi-gcc
sudo chown $USER /opt/cross-pi-gcc
export PATH=/opt/cross-pi-gcc/bin:$PATH
  • Kopirajte zaglavlja jezgre u gornju mapu.
cd ~/gcc_all
cd linux
KERNEL=kernel7
make ARCH=arm64 INSTALL_HDR_PATH=/opt/cross-pi-gcc/aarch64-linux-gnu headers_install
  • Izgradite Binutils.
cd ~/gcc_all
mkdir build-binutils && cd build-binutils
../binutils-2.40/configure --prefix=/opt/cross-pi-gcc --target=aarch64-linux-gnu --with-arch=armv8 --disable-multilib
make -j 8
make install
  • Uredi gcc-12.2.0/libsanitizer/asan/asan_linux.cpp. Dodajte sljedeći dio koda.
#ifndef PATH_MAX
#define PATH_MAX 4096
#endif
  • Napravite djelomičnu verziju gcc-a.
cd ~/gcc_all
mkdir build-gcc && cd build-gcc
../gcc-12.2.0/configure --prefix=/opt/cross-pi-gcc --target=aarch64-linux-gnu --enable-languages=c,c++ --disable-multilib
make -j8 all-gcc
make install-gcc
  • Djelomično izgradite Glibc.
cd ~/gcc_all
mkdir build-glibc && cd build-glibc
../glibc-2.36/configure --prefix=/opt/cross-pi-gcc/aarch64-linux-gnu --build=$MACHTYPE --host=aarch64-linux-gnu --target=aarch64-linux-gnu --with-headers=/opt/cross-pi-gcc/aarch64-linux-gnu/include --disable-multilib libc_cv_forced_unwind=yes
make install-bootstrap-headers=yes install-headers
make -j8 csu/subdir_lib

aarch64-linux-gnu-gcc -nostdlib -nostartfiles -shared -x c /dev/null -o /opt/cross-pi-gcc/aarch64-linux-gnu/lib/libc.so
touch /opt/cross-pi-gcc/aarch64-linux-gnu/include/gnu/stubs.h
  • Natrag na gcc.
cd ~/gcc_all/build-gcc
make -j8 all-target-libgcc
make install-target-libgcc
  • Završite izgradnju glibc.
cd ~/gcc_all/build-glibc
make -j8
make install
  • Završite izgradnju gcc.
cd ~/gcc_all/build-gcc
make -j8
make install

U ovom trenutku imamo potpuni lanac alata za unakrsni kompajler s gcc-om. Mapa gcc_all više nije potrebna. Možete ga izbrisati.</:code19:></:code18:></:code17:></:code16:></:code15:></:code14:></:code13:></:code12:></:code11:></:code10:></:code9:></:code8:></:code7:>

Zgrada Qt6

Postoje dvije mogućnosti za izgradnju Qt6. Postoji "single" (https://download.qt.io/official_releases/qt/6.8/6.8.0/single/qt-everywhere-src-6.8.0.tar.xz) verzija za preuzimanje, koja sadrži qtbase i sve podmodule. Ovo je vrlo teška stvar i treba puno snage i vremena da se sastavi.

Moja preporuka je, da qtbase sastavite kao osnovu i nakon toga sastavite samo svaki podmodul koji vam je potreban zasebno.

  • Napravite mape za sysroot i qt6. Kreiram ove mape u svom workspace/qt-rpi-cross-compilation direktoriju.
cd ~/workspace/qt-rpi-cross-compilation
mkdir rpi-sysroot rpi-sysroot/usr rpi-sysroot/opt
mkdir qt6 qt6/host qt6/pi qt6/host-build qt6/pi-build qt6/src
  • Preuzmite QtBase izvorni kod
cd ~/workspace/qt-rpi-cross-compilation/qt6/src
wget https://download.qt.io/official_releases/qt/6.8/6.8.0/submodules/qtbase-everywhere-src-6.8.0.tar.xz
tar xf qtbase-everywhere-src-6.8.0.tar.xz

Izgradite Qt6 za domaćina

cd ~/workspace/qt-rpi-cross-compilation/qt6/host-build/
cmake ../src/qtbase-everywhere-src-6.8.0/ -GNinja -DCMAKE_BUILD_TYPE=Release -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=$HOME/qt6/host
cmake --build . --parallel 8
cmake --install .

Binarne datoteke bit će u ~/workspace/qt-rpi-cross-compilation/qt6/host

Izgradite Qt6 za rpi

Kopirajte i zalijepite nekoliko mapa iz rpi-ja pomoću rsync putem SSH-a.

cd ~
rsync -avz --rsync-path="sudo rsync" [email protected]:/usr/include workspace/qt-rpi-cross-compilation/rpi-sysroot/usr
rsync -avz --rsync-path="sudo rsync" [email protected]:/lib workspace/qt-rpi-cross-compilation/rpi-sysroot

  • Stvorite datoteku pod nazivom toolchain.cmake u ~/workspace/qt-rpi-cross-compilation/qt6. Morate prilagoditi redak "set(TARGET_SYSROOT /home/factory/workspace/qt-rpi-cross-compilation/rpi-sysroot)" svom okruženju.
