Qt 6.8 navzkrižna kompilacija za Raspberry Pi Vdelana programska

Uvod

V prejšnji seriji blogov

Pisal sem o namestitvi Raspbiana na Raspberry Compute Module in nastavitvi navzkrižne kompilacije za QtCreator na Ubuntu 20.

Ta blogpost je posodobitev na - v tem trenutku - najnovejšo različico 6.8 Qt, raspi OS Bookworm in Ubuntu 22.04 LTS.

Predpogoji

Uporabil sem naslednje trde- in programsko opremo:

Raspberry Pi 4
raspi OS Bookworm, brez priporočene programske opreme
Ubuntu 22.04 LTS
Qt 6.8
QtCreator 14.02

Opombe

Če imate prenosni ali namizni računalnik z dovolj pomnilnika in procesorskih jeder, lahko navzkrižno kompilacijo izvedete v navideznem računalniku. Vendar sem izkusil, da je domači računalnik veliko hitrejši in povzroča manj napak.

Oglejte si poti do datotek in naslove ip v mojih primerih kode in jih prilagodite svojim potrebam.

Nastavitev Raspberry Pi

Prenesite raspiOS s spletne strani https://www.raspberrypi.com/software/operating-systems
2024-07-04-raspios-bookworm-arm64.img.xz: 64bit z Raspberry Pi OS z namizjem (ne s priporočeno programsko opremo)
Sliko prenesite na kartico SD s programom Balena Etcher
Sledite namestitvi in ne pozabite na nastavitve za oddaljeno povezavo (ssh)
Povežite se z RPi s ssh -> v mojem primeru na naslov IP 192.168.2.167 in uporabnika pi -> iz gostitelja Ubuntu

ssh pi@192.168.2.167

Namestite potrebno programsko opremo:

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 gstreamer1.0-omx 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

Ustvarite mapo za namestitev Qt 6:

sudo mkdir /usr/local/qt6

Odkrijte različice gcc, ld in ldd. Izvorno kodo iste različice je treba prenesti za kasnejšo izdelavo navzkrižnega prevajalnika.

Na konec ~/.bashrc dodajte naslednji del kode in posodobite spremembe:

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

Nastavitev Ubuntu 22.04 LTS

Posodobitev na najnovejše različice programskih paketov:

sudo apt update
sudo apt upgrade

Namestite naslednje 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

Zgradite najnovejšo različico cmake iz izvorne kode:

cd ~
wget https://github.com/Kitware/CMake/releases/download/v3.30.5/cmake-3.30.5.tar.gz
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

Sestavite gcc kot navzkrižni prevajalnik

Prenesite potrebno izvorno kodo. Naslednje ukaze spremenite glede na svoje potrebe. V času, ko pripravljam to stran, so:

gcc 12.2.0
binutils 2.40 (različica ld)
glibc 2.36 (različica ldd)

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 binutils-2.40.tar.bz2
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

Ustvarite mapo za namestitev prevajalnika.

sudo mkdir -p /opt/cross-pi-gcc
sudo chown $USER /opt/cross-pi-gcc
export PATH=/opt/cross-pi-gcc/bin:$PATH

Kopirajte glave jedra v zgornjo mapo.

cd ~/gcc_all
cd linux
KERNEL=kernel7
make ARCH=arm64 INSTALL_HDR_PATH=/opt/cross-pi-gcc/aarch64-linux-gnu headers_install

Sestavite program 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

Uredite gcc-12.2.0/libsanitizer/asan/asan_linux.cpp. Dodajte naslednji del kode.

#ifndef PATH_MAX
#define PATH_MAX 4096
#endif

Izvedite delno izgradnjo programa gcc.

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

Delno sestavite 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
install csu/crt1.o csu/crti.o csu/crtn.o /opt/cross-pi-gcc/aarch64-linux-gnu/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

Vrnite se na gcc.

cd ~/gcc_all/build-gcc
make -j8 all-target-libgcc
make install-target-libgcc

Dokončajte gradnjo glibc.

cd ~/gcc_all/build-glibc
make -j8
make install

Dokončajte gradnjo gcc.

cd ~/gcc_all/build-gcc
make -j8
make install

Na tej točki imamo z gcc popolno verigo orodij za navzkrižno prevajanje. Mapa gcc_all ni več potrebna. Lahko jo izbrišete.

Gradnja Qt6

Qt6 lahko sestavite na dva načina. Prenesete lahko različico "single" (https://download.qt.io/official_releases/qt/6.8/6.8.0/single/qt-everywhere-src-6.8.0.tar.xz), ki vsebuje qtbase in vse podmodule. To je zelo težka zadeva in za njeno sestavljanje potrebujete veliko moči in časa.

Moje priporočilo je, da kot osnovo sestavite qtbase in nato sestavite samo vsak podmodul, ki ga potrebujete, posebej.

Ustvarite mape za sysroot in qt6. Te mape ustvarim v svojem delovnem prostoru/qt-rpi-cross-compilation directory.

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

Prenesite izvorno kodo QtBase

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

Sestavite Qt6 za gostitelja

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 bodo v ~/workspace/qt-rpi-cross-compilation/qt6/host

Sestavite Qt6 za rpi

Kopirajte in prilepite nekaj map iz rpi z uporabo rsync prek SSH.

cd ~
rsync -avz --rsync-path="sudo rsync" pi@192.168.2.167:/usr/include workspace/qt-rpi-cross-compilation/rpi-sysroot/usr

rsync -avz --rsync-path="sudo rsync" pi@192.168.2.167:/opt/vc workspace/qt-rpi-cross-compilation/rpi-sysroot/opt

Ustvarite datoteko z imenom toolchain.cmake v ~/workspace/qt-rpi-cross-compilation/qt6. Vrstico "set(TARGET_SYSROOT /home/factory/workspace/qt-rpi-cross-compilation/rpi-sysroot)" morate prilagoditi svojemu okolju.
