Buildroot configuration to reproduce the problem

fw_printenv does not build in current versions of buildroot.

The problem is well known ussue in upstream U-Boot. The good news is that there is a workaround.
The bad news is that the issue is known by the U-Boot developers since last october, but there does not seem to be activity to really fix it.

For the long story see the links in
http://lists.denx.de/pipermail/u-boot/2011-April/089987.html .

Reproduced with current buildroot (2011.02-116-g64b351f) and the attached (minimized) config.

The result is:

CONF config/config.in

make: ***

I solved this problem applying the known workaround this way:

     $(STRIPCMD) $(STRIP_STRIP_UNNEEDED) $@
     ln -sf fw_printenv $(TARGET_DIR)/usr/sbin/fw_setenv
 

This works for me, but I don't know if will for other people, nor if it is general enough to be proposed for mainline buildroot inclusion.

Any observations?

--- Comment #1 from Peter Korsgaard <[email protected]> ---
I was first a bit concerned about how long this env target had been supported (as we support older u-boot versions as well), but it seems like it has been there very long.

Thanks, committed with minor tweaks.
