[Buildroot] Basic stupid questions regarding buildroot

[David Wooff]

Hi,
sorry for these rather basic questions:
1.  If I download the latest version of buildroot, am I tied to a
particular version of the kernel?  I current have an old buildroot (from
late last year and kernel 2.6.30, but I'm going to download the latest
buildroot because I'm having compilation problems (since I did a
"clean") and it has been suggested that I use the latest version.  I
currently build the kernel separately.
2. Regarding pre-requisite "packages" or build tools, if I have to
manually download a toolset of some description, where does it have to
live?  Is this automatically "known" by any application which might want
to use it?  Is there a list of anything I need to manually install
before attempting to build buildroot?
 
Many thanks,
Dave W.

There's a limited number of kernel versions supported for any buildroot
release, but as you are compiling your kernel seperately you are
completely free to choose your kernel version.

The kernel headers version doesn't have to be the same as the kernel
version (it only has to be new enough to provide headers for whatever
features you need).

You mean stuff on the build host? We do a dependency check when you run
make and error out if anything in missing.

Hi, I can answer to the question 1 :
I use buildroot for an arm processoir based board, and I build the 
kernel separately. I work with a 2.6.27 kernel, I use buildroot release 
2010.02, and everything works well. Before I was using release 2009-02, 
but I changed to 2010.02 for the same reason, compilation problems after 
make clean ;)
So I alway use my 2.6.27 kernel, I just changed its configuration to use 
EABI because buildroot release 2010.02 use EABI by default.

Regards,
Cyril HAENEL
