[Openembedded-users] Re : Using External toolchain

[Pranav S]

Hi,
      I am trying to compile packages using external toolchain, but getting
errors saying sh cannot execute oe_sha256sum script. My sourceable scripts
build_source.rc is,
## Update PATH bu providing bitbake command path
export PATH=$OEDIR/../tools/bitbake-1.8.10/bin:${PATH}

## CDPATH must be unset for OE to build
if [ ! -z "$CDPATH" ]; then echo NOTE: Unsetting CDPATH for OE;unset
CDPATH;fi
## PATCH_GET must be unset for OE to build
if [ ! -z "$PATCH_GET" ]; then echo NOTE: Setting PATCH_GET to 0 for
OE;export PATCH_GET=0;fi
### Unset fix for perforce errors
export PATCH_GET=0

export TMPDIR="${OEBUILDDIR}"

HOST_TOOLS=/opt/rmi-linux/hmp10/bin/
TOOLCHAIN=/opt/rmi-linux/hmp10/mipsel-linux/bin/
export PRE_BUILT=/opt/rmi-linux/hmp10/mipsel-linux

PATH=$TOOLCHAIN:$HOST_TOOLS:$PATH

and my machine conf file contains support for toolchain as follows is,

# Following lines added using external toolchain

And when I try to build any package I get following errors,
