Subject: [PATCH] exim_lock: fix lstat-related build errors
|
|
exim_lock fails to cross-compile with the Sourcery CodeBench ARM 2014.05
|
toolchain due the a missing include of sys/types.h, needed for the
|
constants used by fstat() and lstat().
|
|
Discovered when cross-compiling with the Buildroot embedded Linux
|
buildsystem.
|
|
Fixes:
|
|
exim_lock.c:427:30: error: 'S_IFMT' undeclared (first use in this function)
|
if ((statbuf.st_mode & S_IFMT) == S_IFLNK)
|
^
|
exim_lock.c:427:30: note: each undeclared identifier is reported only once for each function it appears in
|
exim_lock.c:427:41: error: 'S_IFLNK' undeclared (first use in this function)
|
if ((statbuf.st_mode & S_IFMT) == S_IFLNK)
|
^
