[root@zheng u-boot-1.1.6]# make all for dir in tools examples post post/cpu ; do make -C $dir _depend ; done make[1]: Entering directory `/home/zheng/workstation/u-boot-1.1.6/tools' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/zheng/workstation/u-boot-1.1.6/tools' make[1]: Entering directory `/home/zheng/workstation/u-boot-1.1.6/examples' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/zheng/workstation/u-boot-1.1.6/examples' make[1]: Entering directory `/home/zheng/workstation/u-boot-1.1.6/post' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/zheng/workstation/u-boot-1.1.6/post' make[1]: Entering directory `/home/zheng/workstation/u-boot-1.1.6/post/cpu' make[1]: Nothing to be done for `_depend'. make[1]: Leaving directory `/home/zheng/workstation/u-boot-1.1.6/post/cpu' make -C tools all make[1]: Entering directory `/home/zheng/workstation/u-boot-1.1.6/tools' make[1]: *** No rule to make target `/home/zheng/workstation/u-boot-1.1.6/include/configs/mysbc405.h', needed by `envcrc.o'.

The error is probably not related to the '_depend' messages. Look at the last two lines. It seems like you're missing the mysbc405.h file.

I think you might be missing a header file. The _depend target is not the problem here: it seems that you didn't tell make how to build mysbc405.h, which it needs to make envcrc.o.

depend' messages. Look at

You need to tell make not to try to make envcrc.o either --- it's trying to make envcrc.o (by compiling envcrc.c, probably) but it knows that it needs mysbc405.h to do that.

Somewhere in the makefiles there is probably a variable which lists objects that need to be built.

From /home/zheng/workstation/u-boot-1.1.6

do find . -type f | xargs grep envcrc

This should list all files that contain "envcrc"
