Here we have a short article on installing Qt Creator on the NVIDIA Jetson TX1. Looky here:
Note: This article is about installing Qt Creator 3.3.1 for Qt 5.5.1 on a Jetson TX1. The Jetson TX1 is flashed using JetPack 2.3.1 and is running L4T 24.2.1.
There are a couple of tricks to installing Qt Creator on the Jetson TX1 from the Ubuntu repositories. Some folks have reported issues installing Qt 5.5 on the TX1, so I revisited the installation we had done for the Jetson TK1.
First, install Qt Creator from the repositories. Open a Terminal and execute:
sudo apt-get install qt5-default qtcreator -y
Second, the compiler needs to be set up. Open Qt Creator, and go to:
Tools->Options->Build & Run->Compilers
Click the ‘Add’ button and select ‘GCC’. In the ‘Compiler path:’ text box, place the path to the gcc compiler. On a standard installation the path is: /usr/bin/gcc.
Here’s the where the first issue comes into play. When GCC is added to the compiler list, it does not set the processor architecture flag correctly. As shown in the video, remedy this issue by modifying the ABI section of the GCC compiler dialog. Change the setting to:
custom – arm – linux – generic – elf – 64 bit
Then save the modifications by clicking ‘Apply’
The third and final step is to add a kit which supports the GCC compiler. Click the ‘Kit‘ tab. The ‘Desktop‘ kit appears to have an issue with setting the compiler. This means that you can find the Desktop kit configuration file and manually modify it, or you can create a new Kit all together. In the video, a new Kit called ‘JetsonTX1’ is created and set to be the default.
Qt Creator is now ready for development, make sure that the JetsonTX1 Kit is selected when creating a new project.
In the video, the standard Qt examples were loaded for demonstration purposes. Also, Qt documentation was loaded. In the Terminal, execute:
$ sudo apt-get install qt5-doc qt5-doc-html qtbase5-doc-html qtbase5-examples -y
The examples are now available.
Getting Qt Creator up and running on the Jetson TX1 requires a couple of tricks, but fortunately we were able to figure them out.
Note: If you are running a version of L4T 24.X before 24.2.1, you may encounter errors associated with a soft link issue with the Mesa OpenGL drivers. In 24.2.1, these have been resolved. For previous versions, you may have to:
$ cd /usr/lib/aarch64-linux-gnu
$ sudo rm libGL.so
$ sudo ln -s /usr/lib/aarch64-linux-gnu/tegra/libGL.so libGL.so
