Created page with " = Preface = Qt has many versions, and may run on defferent OSs.But the toolchain we provide can fit them well. It has the following advantages: *The compilation environmen..."

New page

= Preface =

Qt has many versions, and may run on defferent OSs.But the toolchain we provide can fit them well.

It has the following advantages:

*The compilation environment is consistent with runtime environment.
*Good compatibility.
*Good extensibility.

So the application compiled by the toolchain can run perfectly on our products. And the toolchain can be used on Debian or Ubuntu Desktop Operating System well.

If you meet any problems, please do not hesitate to contact Advantech for help.

= Prerequisites =

Kylin-Enbeded-V10.

== Installing required packages ==

Please login and perform the following commands:
<pre>$ sudo apt-get install -y build-essential
$ sudo apt-get install -y qtcreator
$ sudo apt-get install -y qt5-default
$ sudo apt-get install -y qt5-doc
$ sudo apt-get install -y qt5-doc-html qtbase5-doc-html
$ sudo apt-get install -y qtbase5-examples
$ sudo apt-get install -y qt5-qmake
$ sudo apt-get install -y rsync
$ sudo apt-get install -y gcc-8-arm-linux-gnueabihf g++-8-arm-linux-gnueabihf
$ sudo apt-get install -y gcc-8-aarch64-linux-gnu g++-8-aarch64-linux-gnu
</pre>

Link arm-linux-gnu*-8 to arm-linux-gnu* and aarch64-linux-gnu*-8 to aarch64-linux-gnu*:
<pre>$ sudo su
$ cd /usr/bin
$ for f in $(ls arm-linux-gnu*-8);do ln -sf $f $(echo $f|sed "s/-8//");done
$ for f in $(ls aarch64-linux-gnu*-8);do ln -sf $f $(echo $f|sed "s/-8//");done
$ exit

</pre>

 

== Installing cross toolchain ==

Please download cross compiler toolchain first.

[https://pan.baidu.com/s/1xyRaS1nX7mzPZ8w12pjiAw? ITB202](Password:kroa )

Then execute the following command to unzip the cross compiler tool to the /opt directory

For ITB202
<pre>$ sudo rm -rf /opt/toolchain_Qt_V5.12.12/itb202/
$ sudo mkdir -p /opt/toolchain_Qt_V5.12.12/itb202/
$ sudo tar -xvf itb202_toolchain_Qt_V5.12.12_*.tar.gz -C /opt/toolchain_Qt_V5.12.12/itb202/
</pre>

= Working within QtCreator =

The following example is test on QT5.12.12(qmake version) of Ubuntu18.04.There may be a few differences on other operating system,but the main steps are the same.

Use qtcreator to configure a complete build kit.

== Config QtCreator ---- Qt Versions ==

1. Select Tools --> options --> 

[[File:QtDNK5.png|RTENOTITLE]]

2. Select Qt versions --> Manual -->Add -->

    Path:/opt/toolchain_Qt_V5.12.12/'''itb202'''/sysroot/qmake

[[File:qt_version1.png|800px]]
[[File:qt_version2.png|800px]]

== Config QtCreator ---- Qt Complers ==

1. Select compilers -->

2. Because Gcc and G++ has been installed earlier, the compiler will generally detect it automatically.

    If no Auto-detected, just Add it.

'''Path for''''''RK3588 (64)''':/usr/bin/arrch64-linux-gnu-gcc         

                                   /usr/bin/aarch64-linux-gnu-g++

The following figure uses ITB202  as an example ：

[[File:QtIXDKY6.png|RTENOTITLE]]

== Config QtCreator ---- Qt Debuggers ==

1. Select Debuggers -->

2. The Debuggers selection system buildin,If no Auto-detected , just Add it:

    Path: /usr/bin/gdb

[[File:QtGZ6D5.png|RTENOTITLE]]

== Config QtCreator ---- Qt Cmakes ==

1. Select Cmake -->

2. Similarly,Cmake also uses the system Cmake , if no Auto-detected , just Add it :

    Path: /usr/bin/Cmake

[[File:Qt8D.png|RTENOTITLE]]

== Config QtCreator ---- Qt kits ==

1. Select Kits 

2. Configure "Qt version"、"Compilers"、"Debuggers" and "Cmake" configurations in Kits.

     The picture below uses ITB202 as an example：

== Cannot find Libraries ==

When build, you may get the error like "cannot find -l'''xxxx'''".

"xxxx" is just an example of the library linked to your application.

For example： "cannot find -lsqlite3"

First find the library in toolchain path.

The following commands are taking "RK3568 libsqlite3" as example, other platforms are very similar.
<pre>cd /opt/toolchain_Qt_V5.11.3/rk3568/
find ./ -name libsqlite3.so*
cd ./sysroot/usr/lib/aarch64-linux-gpu
or
cd ./sysroot/lib/aarch64-linux-gpu
ln -s libsqlite3.so.0 libsqlite3.so
</pre>

If you cannot find the library you need in toolchain path, please do not hesitate to contact Advantech for help.
