Subject: sim erc32: Add include path for readline.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2694bce941fcb662ffa2896dc8e886211779ba36;p=binutils-gdb.git

sim erc32: Add include path for readline.

Add a READLINE_CFLAGS variable which adds the include path to the
in-tree readline when using the in-tree readline library.

sim/erc32/ChangeLog:

	* Makefile.in (READLINE_SRC, READLINE_CFLAGS): Add.
	(SIM_EXTRA_CFLAGS): Add READLINE_CFLAGS.
	* configure: Rebuild.
	* configure.ac (READLINE_CFLAGS): Add.
