不使用X11构建Mali驱动程序

Question

I try to build an image for bananaPro without X11 and Wayland support. But I got following error during Mali test binary compilation:

make: Leaving directory '/home/yusuf/yocto/poky/bananaProHf/tmp/work/cortexa7hf-vfp-vfpv4-neon-poky-linux-gnueabi/sunxi-mali/git-r0/git/include'
make -C test test
make[1]: Entering directory '/home/yusuf/yocto/poky/bananaProHf/tmp/work/cortexa7hf-vfp-vfpv4-neon-poky-linux-gnueabi/sunxi-mali/git-r0/git/test'

from test.c:32:
../include/EGL/eglplatform.h:89:22: fatal error: X11/Xlib.h: No such file or directory
compilation terminated.
Makefile:8: recipe for target 'test' failed

When I view 0001-fix-test-build.patch file, I see following lines

test: ../config.mk test.c

    -$(CC) $(CFLAGS) -o $@ test.c -lEGL -lGLESv2
    +$(CC) $(CFLAGS) -I../include -L../../image/usr/lib -o $@ test.c -lEGL -lGLESv2 -lX11

Since the image doesn't support X11, I assumed the X11 libraries shouldn't be included. Isn't that true? How can I solve this problem?

In Yocto, to build image without X11 and Wayland all you have to do is:

DISTRO_FEATURES_remove = " x11 wayland "

This will ignore all the x11 and wayland components.

Edit: The Sunxi Mali Recipe you are using required X11 to compile

PACKAGECONFIG ??= "${@base_contains('DISTRO_FEATURES', 'x11', 'x11', '', d)} \
                  ${@base_contains('DISTRO_FEATURES', 'wayland', 'wayland', '', d)}"
PACKAGECONFIG[wayland] = "EGL_TYPE=framebuffer,,,"
PACKAGECONFIG[x11] = "EGL_TYPE=x11,,virtual/libx11 libxau libxdmcp libdri2,"

One way to work around this is to compile mali with X11 and Wayland, then move all the components to the framebuffer system.

The components that need to move include:

${S}/include/EGL/*.h ${D}${includedir}/EGL/
#In the recipe, this is in do_install, 
#what it does it move the file from ${S}/include/EGL/*.h to ${D}${incluedir}/EGL/

${S}/include/GLES/*.h ${D}${includedir}/GLES/
${S}/include/GLES2/*.h ${D}${includedir}/GLES2/
${S}/include/KHR/*.h ${D}${includedir}/KHR/
${S}/egl.pc ${D}${libdir}/pkgconfig/
${S}/gles_cm.pc ${D}${libdir}/pkgconfig/
${S}/glesv2.pc ${D}${libdir}/pkgconfig/

mv ${D}${libdir}/libMali.so ${D}${libdir}/libMali.so.3
    ln -sf libMali.so.3 ${D}${libdir}/libMali.so
for flib in libEGL.so.1.4 libGLESv1_CM.so.1.1 libGLESv2.so.2.0 ; do
        rm ${D}${libdir}/$flib
        ln -sf libMali.so.3 ${D}${libdir}/$flib
    done

${S}/test/test ${D}${bindir}/sunximali-test
