【Odroid C4】交叉編譯工具鏈安裝以及QT交叉編譯環境搭建

---

虛擬機環境，UBUNTU20.04

---

一、Odroid C4交叉編譯工具鏈安裝

參考ODROID Wiki

• 安裝相關依賴：

sudo apt-get update
sudo apt-get install git lzop build-essential gcc bc libncurses5-dev libc6-i386 lib32stdc++6 zlib1g:i386

• 在這里下載ToolChain
• 解壓到期望的路徑，比如 /opt/toolchains/

sudo mkdir -p /opt/toolchains
sudo tar Jxvf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz -C /opt/toolchains

• 添加環境變量到 ~/.bashrc

export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
export PATH=/opt/toolchains/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/:$PATH

• 更新一下

source ~/.bashrc

到這里安裝就完成了

檢查一下是否能用

aarch64-linux-gnu-gcc -v

輸出結果類似下面這樣：

使用內建 specs。
COLLECT_GCC=aarch64-linux-gnu-gcc
COLLECT_LTO_WRAPPER=/opt/toolchains/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/../libexec/gcc/aarch64-linux-gnu/7.5.0/lto-wrapper
目標：aarch64-linux-gnu
配置為：'/home/tcwg-buildslave/workspace/tcwg-make-release_0/snapshots/gcc.git~linaro-7.5-2019.12/configure' SHELL=/bin/bash --with-mpc=/home/tcwg-buildslave/workspace/tcwg-make-release_0/_build/builds/destdir/x86_64-unknown-linux-gnu --with-mpfr=/home/tcwg-buildslave/workspace/tcwg-make-release_0/_build/builds/destdir/x86_64-unknown-linux-gnu --with-gmp=/home/tcwg-buildslave/workspace/tcwg-make-release_0/_build/builds/destdir/x86_64-unknown-linux-gnu --with-gnu-as --with-gnu-ld --disable-libmudflap --enable-lto --enable-shared --without-included-gettext --enable-nls --with-system-zlib --disable-sjlj-exceptions --enable-gnu-unique-object --enable-linker-build-id --disable-libstdcxx-pch --enable-c99 --enable-clocale=gnu --enable-libstdcxx-debug --enable-long-long --with-cloog=no --with-ppl=no --with-isl=no --disable-multilib --enable-fix-cortex-a53-835769 --enable-fix-cortex-a53-843419 --with-arch=armv8-a --enable-threads=posix --enable-multiarch --enable-libstdcxx-time=yes --enable-gnu-indirect-function --with-build-sysroot=/home/tcwg-buildslave/workspace/tcwg-make-release_0/_build/sysroots/aarch64-linux-gnu --with-sysroot=/home/tcwg-buildslave/workspace/tcwg-make-release_0/_build/builds/destdir/x86_64-unknown-linux-gnu/aarch64-linux-gnu/libc --enable-checking=release --disable-bootstrap --enable-languages=c,c++,fortran,lto --build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu --target=aarch64-linux-gnu --prefix=/home/tcwg-buildslave/workspace/tcwg-make-release_0/_build/builds/destdir/x86_64-unknown-linux-gnu
線程模型：posix
gcc 版本 7.5.0 (Linaro GCC 7.5-2019.12) 

二、QT下載及編譯安裝

1.QT下載

下載鏈接
以5.15.8版本為例
下載完成后，解壓

2.交叉編譯QT

• 更改配置文件：

cd xx/qt-everywhere-src-5.15.8/qtbase/mkspecs/
cp -rf ./linux-aarch64-gnu-g++ ./aarch64-linux-gnu-g++   #這里是為了對應到xplatform，名字無所謂啦
cd aarch64-linux-gnu-g++/
sudo vim qmake.conf

QMAKE_CC                = aarch64-linux-gnu-gcc  //如果搭建其他的交叉編譯環境，就改成對應的交叉編譯工具鏈
QMAKE_CXX               = aarch64-linux-gnu-g++
QMAKE_LINK              = aarch64-linux-gnu-g++
QMAKE_LINK_SHLIB        = aarch64-linux-gnu-g++

• 執行命令

./configure -prefix ~/qt5.15.8_Odroid/ -opensource -confirm-license -release -strip -no-eglfs -linuxfb -qt-zlib -no-gif -qt-libpng -qt-libjpeg -qt-freetype -no-rpath -no-pch -no-avx -no-openssl -no-cups -no-dbus -no-pkg-config -no-glib -no-iconv -xplatform aarch64-linux-gnu-g++ -no-opengl -nomake examples -nomake tools -no-sqlite -skip qtgamepad -skip qtandroidextras -skip qtmacextras -skip qtx11extras -skip qtsensors -skip qtserialbus -skip qtserialport -skip qtwebengine -skip qtwebchannel -skip qtwebsockets -skip qtlocation -skip qtquickcontrols -skip qtpurchasing -skip qtconnectivity -skip qtscxml -skip qtxmlpatterns -skip qtnetworkauth -skip qtspeech -skip qtscript -skip qtremoteobjects -skip qtcharts -skip qtdatavis3d -skip qtwebview
make -j8 && make install

配置QtCreator可以參考

一坑(hisi)未平，一坑(Odroid C4)又起……
學吧，都是芝士(￣▽￣ = ￣︿￣)
