Subject: [PATCH] scripts/gdb: fix lx-version for gdb 7.3-
Date: Wed, 17 Oct 2018 02:36:52 +0000	[thread overview]
Message-ID: <20181017023652.6867-1-changbin.du@gmail.com> (raw)

For gdb version less than 7.3, lx-version only one character.
(gdb) lx-version
L(gdb)

This can be fixed by casting 'linux_banner' as (char *).
(gdb) lx-version
Linux version 4.19.0-rc1+ (changbin@acer) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #21 SMP Sat Sep 1 21:43:30 CST 2018

gdb 7.4 seems to be no such issue.
