Re: Cross compile dont gen QLabel and QPushbutton and Fontconfig pre-condition
I get same kind of issue as described in previous post. Qt is not able to display any text/label whereas windows and controls display well...
My arch is ARM64-Zync (from Xilinx) under Linux. I tried many Qt versions (5.10, 5.7, 5.6, 5.3) that I cross-compiled but issue is the same... I also tried different plugins (linufb, xcb) without success. Qt apps/plugins don't return any error. Everything seems to work well... The only error messages I get are from X11 when using xcb plugin :
XmbTextListToTextProperty result code -2
If I run my Qt apps under a Linux distro provided by Xilinx (with pre-compiled librairies), it works well. If I run the same apps under a Linux distro generated by myself (with Xilinx PetaLinux Yocto tools), it doesn't work, even if I use all the pre-compiled Qt librairies (and so on) extracted from the Linux distro provided by Xilinx !Any idea to solve this ?
Tnx

Hi and welcome to devnet,
Did you compare the Qt related content of both the Xilinx provided and your distribution ? For example do you have fontconfig on both systems ? Do you have fonts installed ? etc.

Hi SGaist,
Thanks for your quick reply !
As you suggested, I compared the /usr/share directory of my 2 distros and indeed /usr/share/fonts was missing in the faulty one...
What is a bit surprising is that Qt don't shout if it don't find any font on the system...Best Regards

Empty folder and missing folder are two different use cases. The first one might not trigger the same code path.

So is your issue solved? If yes, please don't forget to mark your post as such.
