[Interest] Error: Application cannot be started because it failed to load qt platform plugin “eglfs”

[Ramakanthreddy Kesireddy]

Hi Thiago,

The functions are getting used in IMX6 eglfshooks i.e. /qtbase/mkspecs/devices/linux-imx6-g++/qeglfshooks_imx6.cpp.

Thanks and Regards,
Ramakanth

I can't find any of those functions getting used anywhere in Qt source code.

The evidence says they're getting called. Therefore, the only conclusion is that they are called by inline functions from a non-Qt header or from a static library.

Another important fact to remember is that all Qt plugins and libraries are linked with -Wl,--no-undefined. That means those functions *were* found at link time, but not at runtime. That means at least one of the libraries you linked to are not the same as you're running with.

Please recheck ALL library dependencies of that plugin that come from your toolchain. You're running against a library different than that which you compiled with.

Start with the most obvious candidates: the EGL and GLESv2 libraries.
