This commit adds three patches that are needed to fix build issues on musl: - <error.h> not available on musl - structure redefinitions due to direct inclusion of kernel headers - missing <sys/ttydefaults.h> inclusion Patches have been submitted upstream: http://lists.unix-ag.uni-kl.de/pipermail/vpnc-devel/2016-June/004186.html Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Subject: [PATCH] sysdep.h: don't assume <error.h> is available on all Linux
|
|
platforms
|
|
|
|
The current logic in sysdep.h assumes that whenever you have __linux__
|
|
or __GLIBC__ defined, then <error.h> functionality is
|
|
available. However, the <error.h> functionality is a glibc-ism, not
|
|
available in more standard-conformant C libraries such as the musl C
|
|
library. With musl, __linux__ is defined (but of course not
|
|
__GLIBC__). With the current logic, sysdep.h assumes that <error.h> is
|
|
available, which isn't the case.
|
|
|
|
This patch therefore changes the logic to only use <error.h> when
|
|
__GLIBC__ is defined. It fixes the following build error:
|
|
|
|
In file included from tunip.c:87:0:
|
|
sysdep.h:41:19: fatal error: error.h: No such file or directory
|
|
#include <error.h>
