           Product: DRI
           Version: DRI CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: General

When compiling mesa after cloning:

git://anongit.freedesktop.org/mesa/mesa

and running:

./autogen.sh --prefix=$WLD --enable-gles2 --disable-gallium-egl \
      --with-egl-platforms=x11,wayland,drm --enable-gbm --enable-shared-glapi

compiling with make results in:

Something is wrong in src/egl/main/Makefile around here:

# egl_dri2 and egl_glx are built-ins
ifeq ($(filter dri2, $(EGL_DRIVERS_DIRS)),dri2)
LOCAL_CFLAGS += -D_EGL_BUILT_IN_DRIVER_DRI2
LOCAL_LIBS += $(TOP)/src/egl/drivers/dri2/libegl_dri2.a
ifneq ($(findstring x11, $(EGL_PLATFORMS)),)
EGL_LIB_DEPS += $(XCB_DRI2_LIBS)
endif
ifneq ($(findstring drm, $(EGL_PLATFORMS)),)
EGL_LIB_DEPS += -lgbm
INCLUDE_DIRS += -I$(TOP)/src/gbm/main
endif
EGL_LIB_DEPS += $(LIBUDEV_LIBS) $(DLOPEN_LIBS) $(LIBDRM_LIB) $(WAYLAND_LIBS)
endif


Moving:

EGL_LIB_DEPS += -lgbm
INCLUDE_DIRS += -I$(TOP)/src/gbm/main

outside of the if-statement makes the code compile successfully.
