 +If you are using buildroot with full uclibc toolchain, below extra configuration is needed.
 +<code>
 +Toolchain  --->    
 +     [*] Toolchain has IPv6 support?

 +===== Build external source on local disk =====
 +Some customer's application source code is on local disk other than a remote source server. You can direct buildroot to use local source in your package's make file by macro <PACKAGE>_OVERRIDE_SRCDIR. 
 +
 +If the local source package is generated by GNU autotools, define "<PACKAGE>_OVERRIDE_SRCDIR = your source path" is all you need to do. Otherwise, you have to define the other macro "<PACKAGE>_OVERRIDE_RSYNC = yes" as well. This macro tells buildroot to copy your source code to folder "buildroot/output/build/<PACKAGE>_custom/" before compiling.
 +
 +The buildroot make file for your local source may look like:
 +<code>
 +VIDEO_TEST_OVERRIDE_SRCDIR = /home/sonic/projects/test/video_test
 +VIDEO_TEST_OVERRIDE_RSYNC = yes
 +
 +define VIDEO_TEST_BUILD_CMDS
 +        $(MAKE) -C $(@D) $(TARGET_CONFIGURE_OPTS)
 +endef
 +
 +define VIDEO_TEST_INSTALL_TARGET_CMDS
 +        if ! [ -d "$(TARGET_DIR)/bin/" ]; then \
 +                mkdir -p $(TARGET_DIR)/bin/; \
 +        fi
 +        $(INSTALL) -D -m 0755 $(@D)/video_test $(TARGET_DIR)/bin/
 +endef
 +
 +define VIDEO_TEST_CLEAN_CMDS
 +        $(MAKE) -C $(@D) clean
 +endef
 +
 +define VIDEO_TEST_UNINSTALL_TARGET_CMDS
 +        rm -f $(TARGET_DIR)/bin/video_test
 +endef
 +
 +$(eval $(generic-package))
 +</code>
