Cross-Compilation Qt6.4.2 for Jetson Tx2-NX

[steph27]

Hi,

I try to cross-compile Qt6.4.2 for a Jetson Tx2-NX with this carrier board. The image provided contains :

• Embedded linux : Linux tegra-ubuntu 4.9.253-tegra
• GCC : 7.5
• GLIBC : 2.27

I followed this tutorial, with a toolchain with GCC 7.5 but I got this error :

fatal error: charconv: No such file or directory

I found on internet this header is only supported starting from GCC 8.1, so I update the GCC on my board (GCC 8.4).

Now I get this error :

Any hint about what I'm doing wrong ?

@steph27 Did you start the build from scratch (from clean state) after changing the compiler?

[steph27]

Yes I did.

Another question :
For the QT_HOST_PATH, should I use the shared libraries or the static ones as I want to build the static libraries for the Jetson ?

[steph27]

I updated GCC to the version 11.1 and the GLIBC to 2.36.
I have now this error while configurating :

ERROR: C++11 <random> is required and is missing or failed to compile.
