Thanks,

OK, thanks.

I am facing this issue, any clue?

ERROR: Failed to obtain CodeSourcery toolchain version: Execution of '/usr/bin/i686-pc-linux-gnu-gcc -v' failed: command not found
ERROR: Failed to obtain CodeSourcery toolchain version: Execution of '/usr/bin/i686-pc-linux-gnu-gcc -v' failed: command not found

This is what I have in my build/conf/local.conf:

...
TCMODE = "external-sourcery"
EXTERNAL_TOOLCHAIN = "/usr"
TARGET_PREFIX = "arm-none-linux-gnueabi-"
...

The external toolchain does exist:

Laszlo,

Saul forwarded me this email regarding external toolchains.  The "In Progress" version of the YP Reference Manual has a new section on toolchains in general.  This section, combined with the TCMODE glossary entry and a FAQ entry, both in the reference manual, comprise our information on the external toolchain topic.  Let me know what specifically would need additionally addressed and I can get that on my plate to improve the doc set.

Thanks,
Scott
