Hi,thank you Ahsan for you reply.I solved my issue and I succeed in using
external toolchain CodeSourcery2009q1 to cross-compile some packages in my OE
2010.12 release.However I didn't create any symlink of
arm-angstrom-linux-gnueabi-gcc to arm-none-linux-gnueabi-gcc.I added an
instantiation of TARGET_SYS variable to the hints of Denys and Tom (se
reference link in my previous email).It's important to do so in order not to
have errors in the do_install task of external-toolchain-csl.bb recipe.Then, as
a resume, my openembedded/conf/distro/angstrom-2008.1.conf file changed in this
way:
# Set the toolchain type (internal, external) and brand (generic, csl etc.)#
LUCATARGET_VENDOR = "-none"TOOLCHAIN_TYPE ?= "external"TOOLCHAIN_BRAND ?=
"csl"TOOLCHAIN_PATH = "/opt/ti/codesourcery"TARGET_SYS =
"arm-none-linux-gnueabi"TOOLCHAIN_SYSPATH =
"${TOOLCHAIN_PATH}/arm-none-linux-gnueabi"PATH_prepend =
"${TOOLCHAIN_PATH}/bin:"require conf/distro/include/toolchain-external.inc
instead of
# Set the toolchain type (internal, external) and brand (generic, csl
etc.)TOOLCHAIN_TYPE ?= "internal"TOOLCHAIN_BRAND ?= ""
Then it worked.Bye,Luca

Hello Luca,
Probably you need to create symbolic links of arm-angstrom-linux-
gnueabi-gcc to arm-none-linux-gnueabi-gcc. OE assumes that the compiler name is
arm-angstrom-linux-gnueabi-gcc. You can see the "CC" variable value by take
environment of libtool-cross (using -e options) that how OE is creating the
name of compiler.
Regards,
Noor

Subject: [oe] External toolchain
Hi,
I would like to use an external toolchain (CodeSourcery2009q1) to
cross-compile some packages for my beagleboard (more or less the same
that happens in Arago) and then I expect not to download glibc package
and cross-compile again libc, libpthread and so on. I would like to use
the libraries inside my external CodeSourcery SDK.
I followed some
hints by Denys and Tom ( http://lists.linuxtogo.
org/pipermail/openembedded-devel/2010-April/019521.html ) and I put
#
LUCA
TARGET_VENDOR = "-none"
TOOLCHAIN_TYPE ?= "external"
TOOLCHAIN_BRAND ?= "csl"
TOOLCHAIN_PATH = "/opt/ti/codesourcery"
TOOLCHAIN_SYSPATH = "${TOOLCHAIN_PATH}/arm-none-linux-gnueabi"
PATH_prepend = "${TOOLCHAIN_PATH}/bin:"
require
conf/distro/include/toolchain-external.inc
inside my
openembedded/conf/distro/angstrom-2008.1.conf
As you know, cross-
compiler provided by CodeSoucery is arm-none-linux-gnueabi-gcc but I
get the following error with libtool-cross_2.2.6b.bb:

Obviously OE doesn't have to find arm-angstrom-linux-
gnueabi-gcc, but why does it search for arm-angstrom-linux-gnueabi-gcc
instead of arm-none-linux-gnueabi-gcc ?
What's wrong inside angstrom-
2008.1.conf or what am I missing?
Thank you for your support
Luca
