24 load(qt_config)
修改14-23行的內容，改為自己相對應的交叉編譯器絕對路徑，最好是絕對路徑。

執行./configure進行對應的配置，可以用./confgure --help檢視。

./configure -v --prefix=


$pwd/qt5 -release -make libs -xplatform linux-aarch64-gnu-g++ -optimized-qmake -pch -qt-zlib -no-opengl -no-sse2 -no-openssl -no-cups -no-separate-debug-info -nomake examples -nomake tools -device-option cross_compile=/media/u260510/47037fce-de1d-40bd-8cd8-922f0e1edc8e/rk_docs/rk1808/buildroot/output/rockchip_rk1808/host/usr/bin/aarch64-buildroot-linux-gnu-
安裝路徑用–prefix=引數自己指定。cross_compile引數是自己編譯器的絕對路徑。

make
make


install
安裝完成後會在你的安裝目錄下看到以下檔案：

bin  doc  include  lib  mkspecs  plugins  qml  translations
將安裝目錄下的include、 lib、 plugins複製到開發板/opt/qt5目錄下（**注意：**這是我自己的目錄，可以根據自己的實際情況進行修改）

vi /etc/profile
export qt_root=/opt/qt5


export tslib_root=/opt/tslib
