交叉編譯QT 源碼

板子：全志 V3S , arm32位cpu

ubuntu 虛擬機搭建好交叉編譯鏈環境，添加環境變量

ok3399@ubuntu:~$ echo $PATH /opt/OK3399-linux-release/host/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/

使用arm-linux-gcc -v 確認編譯工具安裝OK

解壓QT源碼

復制 make spec 文件
將 linux-arm-gnueabi-g++ 文件夾 復制為新的 arm-linux-g++（和編譯器同名）文件夾，不要修改qt源碼自帶的。

ok3399@ubuntu:/opt/qt/qt-5.13.1S-src/qtbase/mkspecs$ ls aix-g++ integrity-armv7 linux-icc-k1om qdevice.pri win32-clang-msvc aix-g++-64 integrity-armv7-imx6 linux-llvm qmodule.pri win32-g++ android-clang integrity-armv8-rcar linux-lsb-g++ qnx-aarch64le-qcc win32-icc android-g++ integrity-x86 lynxos-g++ qnx-armle-v7-qcc win32-icc-k1om arm-linux-g++ linux-aarch64-gnu-g++ macx-clang qnx-x86-64-qcc win32-msvc common linux-arm-gnueabi-g++ macx-g++ qnx-x86-qcc winrt-arm64-msvc2017 cygwin-g++ linux-clang macx-icc solaris-cc winrt-arm64-msvc2019 darwin-g++ linux-clang-32 macx-ios-clang solaris-cc-64 winrt-arm-msvc2015 devices linux-clang-libc++ macx-tvos-clang solaris-cc-64-stlport winrt-arm-msvc2017 dummy linux-clang-libc++-32 macx-watchos-clang solaris-cc-stlport winrt-arm-msvc2019 features linux-g++ macx-xcode solaris-g++ winrt-x64-msvc2015 freebsd-clang linux-g++-32 modules solaris-g++-64 winrt-x64-msvc2017 freebsd-g++ linux-g++-64 modules-inst unsupported winrt-x64-msvc2019 haiku-g++ linux-icc netbsd-g++ wasm-emscripten winrt-x86-msvc2015 hpuxi-g++-64 linux-icc-32 openbsd-g++ win32-arm64-msvc2017 winrt-x86-msvc2017 hurd-g++ linux-icc-64 qconfig.pri win32-clang-g++ winrt-x86-msvc2019

在copy的make spec 修改 即arm-linux-g++ 下的qmake.conf

ok3399@ubuntu:/opt/qt/qt-5.13.1S-src/qtbase/mkspecs/arm-linux-g++$ ls qmake.conf qplatformdefs.h

修改后如下，使用交叉編譯器的絕對路徑設置 QMAKE_CC。。。，否則可能會找不到編譯器

# # qmake configuration for building with arm-linux-gnueabi-g++ #MAKEFILE_GENERATOR = UNIX CONFIG += incremental QMAKE_INCREMENTAL_STYLE = sublibinclude(../common/linux.conf) include(../common/gcc-base-unix.conf) include(../common/g++-unix.conf)# modifications to g++.conf QMAKE_CC = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-gcc QMAKE_CXX = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-g++ QMAKE_LINK = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-g++ QMAKE_LINK_SHLIB = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-g++# modifications to linux.conf QMAKE_AR = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-ar cqs QMAKE_OBJCOPY = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-objcopy QMAKE_NM = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux-nm -P QMAKE_STRIP = /media/user1/V3SSDK_BUILDROOT/v3ssdk/buildroot/out/host/bin/arm-linux--strip load(qt_config)

編寫構建腳本

#!/bin/sh ./configure -confirm-license \-xplatform arm-linux-g++\-opensource \-verbose \-skip qt3d \-skip qtquickcontrols \-skip qtwebchannel \-skip qtactiveqt \-skip qtandroidextras \-skip qtdeclarative \-skip qtimageformats \-skip qtmacextras \-skip qtx11extras \-skip qtxmlpatterns \-skip qtconnectivity \-skip qtdoc \-skip qtgraphicaleffects \-skip qtlocation \-skip qtmultimedia \-skip qtsensors \-skip qttools \-skip qttranslations \-skip qtwayland \-skip qtwebchannel \-skip qtwebengine \-skip qtwinextras \-no-opengl \-widgets \-prefix /opt/qt/qt_v3s

-xplatform 是目標平臺，使用交叉編譯器的名字即可。
-prefix /opt/qt/qt_v3s 編譯后qt存放位置

執行build腳本后，根據提示進行 make , make install 生成文件確認

ok3399@ubuntu:/opt/qt/qt_v3s$ ls bin doc examples include lib mkspecs plugins
