QT应用程序编译 (QT application compife)准备QT5程序代码(prepare QT5 program code)提示：这里我们使用“Qt5_NMap_CarouselDemo_1.0.tgz”进行演示。
Tips：Here We demonstrate with “Qt5_NMap_CarouselDemo_1.0.tgz".
1）将代码包复制到Linux开发主机
copy code package to Linux development host
将代码包“Qt5_NMap_CarouselDemo_1.0.tgz”复制到“~/my-demo/source_code”。
copy code package“Qt5_NMap_CarouselDemo_1.0.tgz" to "~/my-demo/source_code". This step is completed by yourself. complete this step by yourself in a proper way.
2) Decompress code package decompress code package $ cd ~/my-demo/source_code $ tar zxf Qt5_NMap_CarouselDemo_1.0.tgz ![]()
Compile QT5 application(compile QT5 application)Tips: We compile with commands. 1）Enter the code directoryenter code directory Tips: first we decompress code package "Qt5_NMap_CarouselDemo_1.0.tgz"to"~/my-demo/source_code". $ cd ~/my-demo/source_code/Qt5_NMap_CarouselDemo_1.0/
2) Check QMake check QMake $ qmake –v ![]()
If the current terminal outputs "QMake version 3.0" after executing the command, it means that the cross-compilation tool is configured normally. , 37)]3）Generate Makefile create Makefile $ qmake [color=rgb(11, 0, you can see an extra Makefile with ls after execution of qmake you can see an extra Makefile with ls after execution of qmake 4）Compile compile $ make ![]()
5) Target file target file
target file $ file Qt5_NMap_CarouselDemo ![]()
source file Running QT5 needs the corresponding qml file and content Running QT5 needs the corresponding qml file and content ![]()
Save target executable fileBecause running QT5 program requires qml file and content file, here We copy the entire directory to the target directory for simplicity. $ cp ../Qt5_NMap_CarouselDemo_1.0 ~/my-demo/bin-l31452/ -a ![]()
Application packaging(package application)Instructions(instruction)The burning tool supports burning the file package “my-demo.tar.xz” to the evaluation board. 1) Package package Here we package the whole my-demo directory. $ cd ~ $ tar cjf my-demo.tar.bz2 my-demo Copy application package as target programming file $ cp my-demo.tar.bz2 ~/my-imx6/04_image/image-linux-31452/ ![]()
target programming file
So far,we get a set of programming file except file system from“~/my-imx6/04_image/image-linux-31452/”. including“uboot*.imx”，myimx6*.dtb”，zImage-myimx6”，kernel-modules.tar.bz2”，my-demo.tar.bz2”，So far,we get a set of programming file except file system from“~/my-imx6/04_image/image-linux-31452/”. including“uboot*.imx”，myimx6*.dtb”，zImage-myimx6”，kernel-modules.tar.bz2”，my-demo.tar.bz2”，Now we can program the image we compiled by ourselves referring to programming manual.
Run application on the evaluation boardAfter burning the system, power on the evaluation board again, log in to the system and execute the following commands. : After the burning, supply power for evaluation board,login system and execute commands below.
- /home/root/my-demo/bin-l31452/hello.out
- export DISPLAY=:0
- /home/root/my-demo/bin-l31452/Qt5_NMap_CarouselDemo_1.0/Qt5_NMap_CarouselDemo
Appendix: file system compilationNotes and instructions: 1) The download amount during the original compilation process will exceed 4G. (Hint: You can use some of the files we downloaded to reduce the download amount and save time, which will be mentioned in 7.4). The download of the original compilation exceed 4G. (tips: you can use files we have downloaded in order to reduce downloads and save time, which is going to be mentioned in 7.4). 2) The network connection of the compilation host should preferably use a network that can access www.fackbook.com, otherwise it may be restricted by the domestic firewall and unable to download the software packages required for compilation. 3）The initial compilation may take 2 hours to unlimited time.It depends on the network state and the configuration of the host.（After a rough statistics, It took about 100 minutes to compile QT5 system on the 16-core CPU 16 G memory host except download time。） Customers are requested to decide whether to compile the file system by themselves or use the file system provided by us according to the actual situation. If the file system we provide meets the requirements, it is recommended not to compile by yourself, because the compilation process may cause many errors. Customer may decide whether to compile the file system or use the file system We provide based on the actual situation. If the file system we provide meets the requirements, you had better not to compile by yourself. Since It may be a lot of errors during compilation.
Prepare for compilationInstall software packageInstruction, Yocto compilation relies on some software package. So you need to Install them on the host. $ sudo apt-get install gawk wget git-core diffstat unzip texinfo \ gcc-multilib build-essential chrpath socat ![]()
$ sudo apt-get install libsdl1.2-dev xterm sed cvs subversion \
coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc \

准备源码(prepare source code)1）下载源码
download source code
在网盘中下载 yocto__imx-3.14.52-1.1.0_ga.tar.xz
from network disk download yocto__imx-3.14.52-1.1.0_ga.tar.xz
2）创建工作目录
create working directory
$ mkdir ~/yocto
![]()
3）将源码包复制到工作目录
Copy source code package to working directory
复制“yocto__imx-3.14.52-1.1.0_ga.tar.xz”到“~/my-imx6/02_source”。
copy“yocto__imx-3.14.52-1.1.0_ga.tar.xz”to“~/my-imx6/02_source”。
这一步骤自己采取相应的方式进行
complete this step by yourself in a proper way
4) 解压源码包
decompress source code package
$ cd ~/yocto/
$ tar xf yocto__imx-3.14.52-1.1.0_ga.tar.xz

准备编译需要的软件包(Prepare software package required for compilation)提示1：如果自己网络状况好且能访问境外网站，可以跳过这一节内容。
tips1：If you have a good network and can access a foreign website ,you can skip this section.
提示2：如果是使用我们下载好的一些包，请继续往下。
tips2：If you use the package we have downloaded, please go on to the next step.
提示3：限于网络上传速度的影响及软件包的更新，我们下载的软件包目录中可能不包括
编译需要的全部软件包，但是编译中缺少的软件包编译程序会在编译过程中自行下载。
tips3：As a result of the upload speed and the update of software package , the software package directory we downloaded may not include all the required software packages for compilation.But the compiler package that is missing from compilation will be downloaded on its own during compilation process.1) Download software packagedownload software package Download downloads folder on the network disk（Path: MYZR-通用资源/yocto/downloads. Currently, the folder size is 6~8G）. 2) Copy software package to BSP directory copy software package to BSP directory move downloads to “~/yocto/imx-3.14.52-1.1.0_ga” directory complete this step by yourself in a proper way.
