[Buildroot] unsafe header/library path used in cross-compilation: '-I/usr/include/readline'

[Sjoerd Venema]

Hi Baruch,

Ok, but package BR2_PACKAGE_READLINE is actually selected. Still, I get the
error.
I'm now running a make clean all, to be sure, but I don't think it resolves
the issue. This is my .mk file:

################################################################################
#
# ecasound
#
################################################################################

ECASOUND_VERSION = 2.9.1
ECASOUND_SOURCE = ecasound-$(ECASOUND_VERSION).tar.gz
ECASOUND_SITE = http://ecasound.seul.org/download
ECASOUND_INSTALL_STAGING = NO
ECASOUND_INSTALL_TARGET = YES
#ECASOUND_CONF_OPTS =
ECASOUND_DEPENDENCIES = readline

$(eval $(autotools-package))
