[Buildroot] gcc 5.2.0 not supported?

[Buildroot] gcc 5.2.0 not supported?

[Ron Eggler]

Hi,

I've build a crosstoolchain for powerpc using crosstools-NG today and I 
wanted to use buildroot to compile a kernel for my system.
Now, turns out I'm getting:

 >>> toolchain-external Configuring Incorrect selection of gcc version: 
expected 4.3.x, got 5.2.0

on make and when I started Googling around, I found this thread 
http://lists.busybox.net/pipermail/buildroot/2015-July/133170.html from 
July 2015 that essentially says that gcc 5.2.0 is not supported.
Now I'm wondering if this is this still the case?

Also, before I had set the kernel headers to 4.3.x in menu config, I 
would get the same error but saying:

 >>> toolchain-external Configuring Incorrect selection of kernel 
headers: expected 2.6.x, got 4.3.x

Now as I've moved up the header version to match 4.3.x, I get the error 
pasted above. How can that be? How can I get my kernel built using the 
crosstools-NG toolchain?

Thanks,
Ron

You need to select your external toolchain version in Toolchain -> External 
toolchain gcc version. 4.3.x is the default, you need to change it to 5.x.

The linked messages is about the Buildroot internal toolchain. It has noting 
to do with you case.

Here again you need to set 'External toolchain kernel headers series' to the 
version of your toolchain kernel headers.

Hope this helps,

Alright, I think that's what I was missing.
