Qt 6.8 Kompilasi Silang untuk Raspberry Pi Perisian terbenam

Pengenalan

Dalam siri catatan blog sebelumnya

Saya menulis tentang pemasangan Raspbian pada Modul Pengiraan Raspberry dan kompilasi silang persediaan untuk QtCreator pada Ubuntu 20.

Catatan blog ini ialah kemas kini kepada - pada masa ini - versi terbaru 6.8 Qt, raspi OS Bookworm dan Ubuntu 22.04 LTS.

Prasyarat

Saya menggunakan perisian keras dan perisian berikut:

Raspberry Pi 4
raspi OS Bookworm, tanpa perisian yang disyorkan
Ubuntu 22.04 LTS
Qt 6.8
QtCreator 14.02

Nota

Jika anda mempunyai komputer riba atau komputer meja dengan teras RAM dan CPU yang mencukupi, anda boleh melakukan kompilasi silang dalam mesin maya. Tetapi saya membuat pengalaman, bahawa komputer asli jauh lebih pantas dan menghasilkan lebih sedikit ralat.

Sila lihat laluan fail dan alamat ip dalam contoh kod saya dan sesuaikan dengan keperluan anda.

Sediakan Raspberry Pi

Muat turun raspiOS daripada https://www.raspberrypi.com/software/operating-systems
2024-07-04-raspios-bookworm-arm64.img.xz: 64bit dengan OS Raspberry Pi dengan desktop (bukan dengan Perisian yang disyorkan)
Imej kilat ke kad SD dengan Balena Etcher
Ikut pemasangan dan jangan lupa tetapan untuk sambungan jauh (ssh)
Sambung ke RPi dengan ssh -> dalam kes saya ke alamat IP 192.168.2.167 dan pengguna pi -> daripada hos Ubuntu anda

ssh pi@192.168.2.167

Pasang perisian yang diperlukan:

Buat folder untuk pemasangan Qt 6:

sudo mkdir /usr/local/qt6

Temui versi gcc, ld dan ldd. Kod sumber versi yang sama hendaklah dimuat turun untuk membina pengkompil silang kemudian.

Lampirkan sekeping kod berikut pada penghujung ~/.bashrc dan kemas kini perubahan:

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

Sediakan Ubuntu 22.04 LTS

Kemas kini kepada versi terkini pakej perisian:

sudo apt update
sudo apt upgrade

Pasang pakej berikut:

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

Bina versi cmake terkini daripada sumber:

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

Bina gcc sebagai pengkompil silang

Muat turun kod sumber yang diperlukan. Anda harus mengubah suai arahan berikut mengikut keperluan anda. Buat masa saya membuat halaman ini, ialah:

GCC 12.2.0
Binutils 2.40 (versi LD)
GLIBC 2.36 (versi 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

Buat folder untuk pemasangan pengkompil.

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

Salin pengepala kernel dalam folder di atas.

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

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

Edit gcc-12.2.0/libsanitizer/asan/asan_linux.cpp. Tambah sekeping kod berikut.

#ifndef PATH_MAX
#define PATH_MAX 4096
#endif

Lakukan pembinaan separa 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

Membina sebahagiannya 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

Kembali ke gcc.

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

Selesai membina glibc.

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

Selesai membina gcc.

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

Pada ketika ini, kami mempunyai rantaian alat pengkompil silang penuh dengan gcc. Folder gcc_all tidak diperlukan lagi. Anda boleh memadamkannya.</:code19:></:code18:></:code17:></:code16:></:code15:></:code14:></:code13:></:code12:></:code11:></:code10:></:code9:></:code8:></:code7:>

Bangunan Qt6

Terdapat dua kemungkinan untuk membina Qt6. Terdapat versi "single" (https://download.qt.io/official_releases/qt/6.8/6.8.0/single/qt-everywhere-src-6.8.0.tar.xz) untuk dimuat turun, yang mengandungi qtbase dan semua submodul. Ini adalah perkara yang sangat berat dan memerlukan banyak kuasa dan masa untuk menyusunnya.

Cadangan saya ialah, untuk menyusun qtbase sebagai asas dan selepas itu menyusun hanya setiap submodul yang anda perlukan secara berasingan.

Buat folder untuk sysroot dan qt6. Saya membuat folder ini dalam direktori workspace/qt-rpi-cross-compilation saya.

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

Muat turun kod sumber 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

Bina Qt6 untuk hos

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 .

Perduaan akan berada dalam ~/workspace/qt-rpi-cross-compilation/qt6/host

Bina Qt6 untuk rpi

Salin dan tampal beberapa folder daripada rpi menggunakan rsync melalui 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:/lib workspace/qt-rpi-cross-compilation/rpi-sysroot
rsync -avz --rsync-path="sudo rsync" pi@192.168.2.167:/usr/lib 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

Buat fail bernama toolchain.cmake dalam ~/workspace/qt-rpi-cross-compilation/qt6. Anda perlu melaraskan baris "set(TARGET_SYSROOT /home/factory/workspace/qt-rpi-cross-compilation/rpi-sysroot)" kepada persekitaran anda.

Tambah Submodul Qt

Tambah modul QML

Muat turun kod sumber:
