0. 环境
mizar z7010
vivado 2018.3
petalinux 2018.3
ubuntu18
1. 获取linux-qt
1.1 下载
petalinux2018.3配套的qt版本是5.9.6。
下载地址：
https://download.qt.io/new_archive/qt/5.9/5.9.6/
下载
qt-opensource-linux-x64-5.9.6.run
qt-everywhere-opensource-src-5.9.6.tar.xz
1.2 安装
sudo chmod 777 qt-opensource-linux-x64-5.9.6.run
./qt-opensource-linux-x64-5.9.6.run-> Next
-> 这里需要注册一个账号，并登录
-> Next
-> Installation Folder: /home/xxjianvm/Qt5.9.6 -> Next
-> Select Components -> 勾选 Desktop gcc 64-bit，勾选 Qt Charts，勾选 Developer and Designer Tools -> Next

-> Install
1.3 界面 helloworld
通过开始界面打开 Qt Creator
1.3.1 创建工程
Qt Creator -> File -> New File or Project -> Application -> Qt Widgets Application -> choose
Location
-> Name: hello_qt
-> Create in: /home/xxjianvm/work/workspace_qt/
-> Next
Details
-> Class Information: hello_qt -> Next
Summary -> Finish
1.3.2 编译
问题：Could not determine which "make" command to run
解决办法：sudo apt install make
问题：/bin/sh: 1: g++: not found
解决办法：sudo apt install g++
问题：/usr/bin/ld: cannot find -lGL
解决办法：find /usr/lib/ -name "libGL*"
sudo ln -s /usr/lib/x86_64-linux-gnu/libGL.so.1 /usr/lib/libGL.so
1.3.2 修改界面
双击 hello_qt/Forms/hello_qt.ui
添加 Push Button ->
-> objectName: Btn_Hello
-> 右键 -> Go to slot... -> clicked() -> OK
修改 hello_qt.cpp：
#include <QtWidgets/QMessageBox>
void hello_qt::on_Btn_Hello_clicked()
{
QMessageBox msgBox;
msgBox.setText("Hello");
msgBox.exec();
}
编译运行
2. 安装sdk
前文petalinux篇生成了sdk。
把
/home/dell/work/mizar/linux_sd_adda/images/linux/sdk.sh
拷贝到
/home/xxjianvm/work/mizar/sdk.sh安装
chmod +x sdk.sh
./sdk.sh
安装到
/opt/petalinux/2018.3测试
source /opt/petalinux/2018.3/environment-setup-cortexa9hf-neon-xilinx-linux-gnueabi
arm-xilinx-linux-gnueabi-gcc -v打开 qtcreator
source /opt/petalinux/2018.3/environment-setup-cortexa9hf-neon-xilinx-linux-gnueabi
/home/xxjianvm/Qt5.9.6/Tools/QtCreator/bin/qtcreator注意打开qtcreator前需要source SDK的交叉编译环境。

3.3 Qt Versions
-> Build & Run -> Qt Versions -> Manual -> Add ->
-> Version name: Qt %{Qt:Version} (zynq7)
-> qmake location: /opt/petalinux/2018.3/sysroots/x86_64-petalinux-linux/usr/bin/qt5/qmake
3.4 Kits
-> Build & Run -> Kits -> Manual -> Add
-> Name: zynq7

4. 界面 helloworld
通过开始界面打开 Qt Creator
4.1 创建工程
Qt Creator -> File -> New File or Project -> Application -> Qt Widgets Application -> choose
Location
-> Name: hello2_qt
-> Create in: /home/xxjianvm/work/workspace_qt/
-> Next
Kits ->

export QT_QPA_PLATFORM=linuxfb
chmod +x hello2_qt
./hello2_qt
