Fix pushed in:
http://bazaar.launchpad.net/~codership/galera/3.x/revision/175

Note that this requires clang 3.4. clang 3.2 had utterly broken warnings.

[Raghavendra D Prabhu (raghavendra-prabhu)]

It builds fine with strict_build_flags=0 for now.

[Alex Yurchenko (ayurchen)]

It should build fine even without it:
CC=clang CXX=clang++ scons -j4

[Raghavendra D Prabhu (raghavendra-prabhu)]

With strict_build_flags=1 (the default and it enables -Werror) it fails at first warning here:

galerautils/src/gu_mutex.c:15:1: error: unused variable 'gu_mutex_init' [-Werror,-Wunused-const-variable]
gu_mutex_init = { .target_mutex = PTHREAD_MUTEX_INITIALIZER,
^

Other places where it fails:

gcs/src/gcs_act_proto.c:28:21: warning: unused variable 'PROTO_ACT_ID_OFFSET' [-Wunused-const-variable]
static const size_t PROTO_ACT_ID_OFFSET = 0;
                    ^

                    ^

                           ^
gcs/src/gcs_act_proto.c:36:28: warning: unused variable 'PROTO_AT_MAX' [-Wunused-const-variable]
static const unsigned char PROTO_AT_MAX = 0xFF;

With these warnings ignored (tested with CPPFLAGS="-Wno-unused-const-variable") it builds fine.

[Alex Yurchenko (ayurchen)]

Ok, nothing of the kind happens in my or Teem's environments. I'm using Ubuntu 13.10 and clang-3.4.

[Raghavendra D Prabhu (raghavendra-prabhu)]

Not sure why it is not happening on your system, but they do look like unused variables to me.

Seeing another error now:
