[Buildroot] make rebuilds cross tools every time ?

[Buildroot] make rebuilds cross tools every time ?

[Jeff Steele]

Hi,

I'm brand new to buildroot, and so far I'm very pleased with it.  One
problem I've been having is that it seems to rebuild uClibc and the
cross compiler/toolchain *every time* I type "make".

For example, tar-1.18 failed to compile, so I edited tar.mk to bump the
version up to 1.20.  Then I did:

# rm -rf tar-1.18
# make

Before I find out if the new version of tar compiles (it does, BTW...),
I have to wait for the whole toolchain to be rebuilt.

Am I doing something wrong ?  Shouldn't the toolchain be independent of
target apps ?


THx


BTW, I'm using buildroot-2009.02, building for armeb, host is x86.

I had it recompiling Linux everytime on one system and now, on this  
one, it recompiles DBUS.

Like you I'm new to buildroot and don't even know WHERE to start  
looking.
