The symbols are defined in gpu-core/usr/include/EGL/eglvivante.h</P><P>The configure step of qtbase uses fbGetDisplayByIndex() to determine if the vivante backend shall be compiled. The same function is also used functionally in QT.</P><P>Are theses symbols missing on purpose? If yes, in which library are they available now?</P> Tue, 17 Dec 2024 15:50:57 GMT https://community.nxp.com/t5/i-MX-Processors/fbGetDisplayByIndex-missing-from-libEGL-so-since-imx-gpu-viv-6-4/m-p/2015418#M232104 klarinettli 2024-12-17T15:50:57Z https://community.nxp.com/t5/i-MX-Processors/fbGetDisplayByIndex-missing-from-libEGL-so-since-imx-gpu-viv-6-4/m-p/2015857#M232129 <P>Hello,<BR /><BR />Which platform are you based on?
