Qt 6.8 Mchanganyiko wa msalaba kwa Raspberry Pi Programu

Utangulizi

Katika mfululizo uliopita wa blogposts

Niliandika juu ya usakinishaji wa Raspbian kwenye Moduli ya Raspberry Compute na usanidi mkusanyiko wa msalaba kwa QtCreator kwenye Ubuntu 20.

Makala hii ni sasisho kwa - kwa wakati huu - toleo jipya zaidi la 6.8 la Qt, raspi OS Bookworm na Ubuntu 22.04 LTS.

Mahitaji ya awali

Nilitumia programu ngumu na ngumu zifuatazo: *Raspberry Pi 4 *raspi OS Bookworm, bila programu iliyopendekezwa *Ubuntu 22.04 LTS *Qt 6.8 *QtCreator 14.02

Madokezo

Ikiwa una kompyuta ndogo au kompyuta ya mezani iliyo na cores za kutosha za RAM na CPU, unaweza kufanya mkusanyiko wa msalaba kwenye mashine pepe. Lakini nilifanya uzoefu, kwamba kompyuta ya asili ni haraka sana na hutoa makosa kidogo.

Angalia njia za faili na anwani za ip katika mifano yangu ya nambari na uyarekebishe kwa mahitaji yako.

Usanidi wa Raspberry Pi

Pakua raspiOS kutoka https://www.raspberrypi.com/software/operating-systems
2024-07-04-raspios-bookworm-arm64.img.xz: 64bit na Raspberry Pi OS na desktop (sio kwa Programu iliyopendekezwa)
Picha ya kiwango cha SD-kadi na Balena Etcher
Fuata ufungaji na usisahau mpangilio wa kuunganisha mbali (ssh)
Unganisha kwa RPi na ssh -> kwa upande wangu kwa anwani ya IP 192.168.2.167 na mtumiaji pi -> kutoka kwa mwenyeji wako wa Ubuntu

ssh [email protected]

Sakinisha programu inayohitajika:

Tengeneza folda ya usakinishaji wa Qt 6:

sudo mkdir /usr/local/qt6

Kugundua matoleo ya gcc, ld na ldd. Msimbo wa chanzo wa toleo moja unapaswa kupakuliwa ili kujenga mkusanyaji msalaba baadaye.

Ambatisha kipande cha msimbo kinachofuata hadi mwisho wa ~/.bashrc na usasishe mabadiliko:

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

Sanidi Ubuntu 22.04 LTS

Sasisha kwa matoleo ya hivi karibuni ya vifurushi vya programu:

sudo apt update
sudo apt upgrade

Sakinisha vifurushi vifuatavyo:

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

Jenga toleo la hivi karibuni la cmake kutoka kwa chanzo:

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

Jenga gcc kama mkusanyaji wa msalaba

Pakua msimbo wa chanzo muhimu. Unapaswa kurekebisha amri zifuatazo kwa mahitaji yako. Kwa wakati mimi kufanya ukurasa huu, wao ni:

GCC 12.2.0
Binutils 2.40 (toleo la LD)
glibc 2.36 (toleo la LDD)

cd ~
mkdir gcc_all && cd gcc_all
wget https://ftpmirror.gnu.org/binutils/binutils-2.40.tar.bz2

rm *.tar.*
cd gcc-12.2.0
contrib/download_prerequisites

Tengeneza folda kwa usakinishaji wa mkusanyaji.

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

Nakili vichwa vya kernel kwenye folda iliyo hapo juu.

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

Kujenga 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

Hariri gcc-12.2.0/libsanitizer/asan/asan_linux.cpp. Ongeza kipande cha msimbo ufuatao.

#ifndef PATH_MAX
#define PATH_MAX 4096
#endif

Fanya ujenzi wa sehemu ya 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

Kwa kiasi fulani kujenga 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

touch /opt/cross-pi-gcc/aarch64-linux-gnu/include/gnu/stubs.h

Rudi kwa gcc.

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

Kumaliza ujenzi wa glibc.

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

Kumaliza ujenzi wa gcc.

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

Kwa wakati huu, tuna mnyororo kamili wa zana ya kukusanya msalaba na gcc. Folda gcc_all haiitaji tena. Unaweza kuifuta.</:code19:></:code18:></:code17:></:code16:></:code15:></:code14:></:code13:></:code12:></:code11:></:code10:></:code9:></:code8:></:code7:>

Ujenzi wa Qt6

Kuna uwezekano wa kujenga Qt6. Kuna toleo la "single" (https://download.qt.io/official_releases/qt/6.8/6.8.0/single/qt-everywhere-src-6.8.0.tar.xz) la kupakua, ambalo lina qtbase na submodules zote. Hii ni mambo mazito sana na inahitaji nguvu nyingi na wakati wa kuikusanya.

Pendekezo langu ni, kukusanya qtbase kama msingi na baadaye kukusanya tu kila submodule unahitaji tofauti.

Tengeneza folda kwa sysroot na qt6. Ninaunda folda hizi kwenye nafasi yangu ya kazi / saraka ya qt-rpi-cross-compilation.

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

Pakua msimbo wa chanzo wa 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

Jenga Qt6 kwa mwenyeji

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 .

Binaries itakuwa katika ~/workspace/qt-rpi-cross-compilation/qt6/host

Jenga Qt6 kwa rpi

Nakili na ubandike folda chache kutoka rpi kwa kutumia rsync kupitia SSH.

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

rsync -avz --rsync-path="sudo rsync" [email protected]:/opt/vc workspace/qt-rpi-cross-compilation/rpi-sysroot/opt

Unda faili inayoitwa toolchain.cmake katika ~/workspace/qt-rpi-cross-compilation/qt6. Unahitaji kurekebisha mstari "seti(TARGET_SYSROOT /home/factory/workspace/qt-rpi-cross-compilation/rpi-sysroot)" kwa mazingira yako.
