I’m encountering an issue when running an application on my Yocto-based system, and I’m getting the error message: “Failed to start Flutter renderer: No GL implementation is available.” Additionally, when I check the existence of the ‘gtk±3.0’ package using pkg-config, it shows that the ‘gl’ package is not found in the search path and suggests adding the directory containing ‘gl.pc’ to the PKG_CONFIG_PATH environment variable.
root@apalis-imx8-07013820:/usr/lib/pkgconfig# pkg-config --exists --print-errors 'gtk+-3.0'
Package gl was not found in the pkg-config search path.
Perhaps you should add the directory containing `gl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'gl', required by 'epoxy', not found
I have already added the ‘mesa’ package to my local.conf, but it seems that ‘gl.pc’ is not present in the ‘/usr/lib/pkgconfig’ directory. When I open the ‘epoxy.pc’ file, it shows the following content:
prefix=/usr
libdir=${prefix}/lib
includedir=${prefix}/include
epoxy_has_glx=1
epoxy_has_egl=1
epoxy_has_wgl=0
Name: epoxy
Description: GL dispatch library
Version: 1.5.10
Requires.private: x11, egl, gl egl
Libs: -L${libdir} -lepoxy
Libs.private: -ldl
Cflags: -I${includedir}
I would appreciate any guidance on how to properly install OpenGL or resolve the “No GL implementation is available” error in Yocto. Additionally, I’d like to know how to ensure that ‘gl.pc’ is available in the ‘/usr/lib/pkgconfig’ directory. Thank you for your help!
