Using external cross-compiler

Using external cross-compiler

[Mikhail Boiko]

Hi,

I've got some issues with configuring OE to use external cross compiler
(CodeSourcery 2011.03).
II've added this lines to my local.conf file:
TARGET_VENDOR = "-none"
TOOLCHAIN_TYPE = "external"
TOOLCHAIN_BRAND = "csl"
TOOLCHAIN_PATH = "/home/mike/x-tools/cs_2011_03"
TOOLCHAIN_SYSPATH = "${TOOLCHAIN_PATH}/arm-none-linux-gnueabi"
PATH_prepend = "${TOOLCHAIN_PATH}/bin:"

With this config, task "do_configure:" for "libtool-cross" fails. Taking
look at do_configure log i notice that OE run following command for
configuring:

/home/mike/freescale/angstrom-setup-scripts/build/tmp-angstrom_2008_1/work/armv7a-angstrom-linux-gnueabi/libtool-cross-2.2.6b-r28.1/libtool-2.2.6b/configure

As you see, it try to use arm-angstrom-linux-gnueabi when I have
only arm-none-linux-gnueab avaliable.
Please, give some advices to solve this sissue.

Thanks

So the distro's TARGET_VENDOR is not being overridden; according to [1] you 
need to set TOOLCHAIN_VENDOR rather than TARGET_VENDOR so that this happens.
