I still get the same error with this defconfig:

BR2_armeb=y
BR2_cortex_a9=y
BR2_ARM_EABIHF=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_ERLANG=y
BR2_PACKAGE_EJABBERD=y

But I can see the missing libs to be present, except the path to them is
not specified in the compile line:
    staging/usr/lib/erlang/usr/lib/liberl_interface.a
    staging/usr/lib/erlang/usr/lib/libei.a

Except it seems weird to have ".../erlang/usr/lib/..." to begin with.

Yann E. MORIN.
