Hi David, I'm curious about your compilation flags since they apparently show warnings I do not see :-) Here is what I have, with gcc version 4.8.2
/bin/bash ../libtool --tag=CXX --mode=compile ccache g++ -DHAVE_CONFIG_H -I. -D__CEPH__ -D_FILE_OFFSET_BITS=64 -D_REENTRANT -D_THREAD_SAFE -D__STDC_FORMAT_MACROS -D_GNU_SOURCE -DCEPH_LIBDIR=\"/usr/local/lib\" -DCEPH_PKGLIBDIR=\"/usr/local/lib/ceph\" -DGTEST_HAS_TR1_TUPLE=0 -Wall -Wtype-limits -Wignored-qualifiers -Winit-self -Wpointer-arith -Werror=format-security -fno-strict-aliasing -fsigned-char -rdynamic -ftemplate-depth-1024 -Wnon-virtual-dtor -Wno-invalid-offsetof -fno-builtin-malloc -fno-builtin-calloc -fno-builtin-realloc -fno-builtin-free -Wstrict-null-sentinel -Wuninitialized -Wall -g -MT erasure-code/lrc/libec_lrc_la-ErasureCodeLrc.lo -MD -MP -MF erasure-code/lrc/.deps/libec_lrc_la-ErasureCodeLrc.Tpo -c -o erasure-code/lrc/libec_lrc_la-ErasureCodeLrc.lo `test -f 'erasure-code/lrc/ErasureCodeLrc.cc' || echo './'`erasure-code/lrc/ErasureCodeLrc.cc and it fails to notice the warning that requires this patch https://github.com/ceph/ceph/pull/2393/files Cheers -- Loïc Dachary, Artisan Logiciel Libre
