[meta-freescale] [meta-fsl-arm][PATCH] gpu-viv-bin-mx6q: Adding support to install Wayland GPU libs

[Abhijit Potnis]

Hello Otavio,

Ya, Its very confusing ! :-)
The following snippet from the .inc file

    # We'll only have one backend here so we rename it to generic name
    # and avoid rework in other packages, when possible
    mv ${D}${libdir}/libEGL-${backend}.so ${D}${libdir}/libEGL.so.1
    ln -sf libEGL.so.1 ${D}${libdir}/libEGL.so
    mv ${D}${libdir}/libGAL-${backend}.so ${D}${libdir}/libGAL.so
    mv ${D}${libdir}/libVIVANTE-${backend}.so ${D}${libdir}/libVIVANTE.so



Renames all the -wl.so backend files to generic files. Like the
libGAL-wl.so is renamed to libGAL.so. Hence was my reason to say that the
default .pc files will do the job. The default .pc files are copied by this
piece of code in the present patch.

+        install -m 0644 ${WORKDIR}/egl.pc ${D}${libdir}/pkgconfig/egl.pc
+        install -m 0644 ${WORKDIR}/glesv1_cm.pc
${D}${libdir}/pkgconfig/glesv1_cm.pc
+        install -m 0644 ${WORKDIR}/glesv2.pc
${D}${libdir}/pkgconfig/glesv2.pc


Rest of the files pertaining to back-ends ( -x11.so, -fb.so ) other that
the one selected in DISTRO_FEATURE will be cleaned accordingly in the
do_install() step and what end up in the image are the .so's without the
backend suffix.

This is my understanding of the situation. I hope I haven't wrongly
analyzed this. Plz do let me know if I am wrong.

Regards,
Abhijit
