hi all, i read the Readme in the top directory of U-boot 1.3.2. i hope this subject is appropriate. i have a question on the makefile, i want to know where is the $obj define, but it seem it define implicitly when use it.

sample: VERSION = 1 PATCHLEVEL = 3 SUBLEVEL = 2 EXTRAVERSION = U_BOOT_VERSION = $(VERSION).$(PATCHLEVEL).$(SUBLEVEL)$(EXTRAVERSION) VERSION_FILE = $(obj)include/version_autogenerated.h

so my question is, where is the version_autogenerated.h file? because i couldn;t find it, so i am not sure what is the purpose of this line. please enlighten me on the usage of the the $obj if possible. i am new to u-boot, thank you.

regards,-keo
