[U-Boot] fw_printenv cross compilation issue

[Elie De Brauwer]

Hi List,

I tried crosscompiling fw_printenv lately (on 2011.03 RC1) but I kept 
ending with a natively compiled version of fw_printenv. When looking at 
the tools/env/Makefile I saw it was using $(HOSTCC) and friends, basicly 
ever since: 
http://git.denx.de/?p=u-boot.git;a=commitdiff;h=abd315a1357ab05e82f0d61ebad666bc0d5378c3

Is there a rationale for this ? Just reverting this change to
http://git.denx.de/?p=u-boot.git;a=blob;f=tools/env/Makefile;hb=78acc472d9719316f22e002a009a998d9ceec29d

Makes building a crosscompiled fw_printenv possible again.

gr
E.

Yes, there is an issue requiring to compile the env tools with native
compiler.

You do not need, try this:

	make HOSTCC=<your CC cross-compiler> env

for example, make HOSTCC=arm-linux-gcc env

There is a rationale for that, and Mike Frisinger explained it when
this patch was being discussed, and later again.  Please see the
archives.

I have to admit that I share your confusion, but even rational is
relative ;-)

Best regards,

Allright,

Thanks for the info, guessed reading some older docs on the internet 
confused me.
