Install Qt in pcsag

Many gamers must have been familiar with the embedded linux system, and have been engaged in qtopia. This stuff has been compiled on the host machine and asked a lot, so some gamers have to wait. Here, we will introduce how to install Qt on pcduino without cross-compilation and install it directly and run it directly. Because the Qt library is large, we recommend that you create a larger SD card and start it as an SD card. The installation steps are as follows: 1. Download and install qtcreator.

Sudo apt-get install qtcreator

After the installation is complete, you will see the qt IDE. Are you familiar with it, but this is not available yet, because there is no Qt library in it.

2. Download Qt

Go to the official Qt website to download the qt library.

Http://qt-project.org/downloads

Download the embedded version. After the download is complete, decompress the package and enter the decompressed file.

3. Install the dependency File

Sudo apt-get install mesa-common-dev freeglut3 freeglut3-dev libqglviewer-dev-common

4. Configure the Qt library. The pcloud video card mail400 has powerful functions. Here we compile opengl

./Configure-no-pch-opengl -- prefix =/usr/local/qt/

If you do not have the/usr/local/qt directory, create one.

5. Compile and install

Make

Sudo make install

This process will take a long time. I personally tested it and it takes 36 hours to compile and install it. No error will be reported in the middle. You can rest assured.

6. Set Environment Variables

Add the following two lines at the end of/etc/profile:

PATH = "$ PATH:/usr/local/qt/bin"

Export PATH

7. Set Qtcreator (you can view it only after logging in)

In this way, you can start your embedded Qt journey.

8. Test.

This camera project, CameraRead.zip, you can download and test.
