Hi! We're getting a compile error when trying to compile PBXT+Maria on ppc MacOS X: http://askmonty.org/buildbot/builders/macosx-g5-dbg/builds/12/steps/compile… looking at the bottom there, one sees: if ccache gcc -DHAVE_CONFIG_H -I. -I. -I../../../include -I../../../include -I../../../include -I../../../regex -I../../../storage/innobase/include -I../../../sql -I. -g -Wimplicit -Wreturn-type -Wswitch -Wtrigraphs -Wcomment -W -Wchar-subscripts -Wformat -Wparentheses -Wsign-compare -Wwrite-strings -Wunused-function -Wunused-label -Wunused-value -Wunused-variable -Wreorder -Wctor-dtor-privacy -Wnon-virtual-dtor -felide-constructors -fno-exceptions -fno-rtti -DUNIV_MUST_NOT_INLINE -DEXTRA_DEBUG -DFORCE_INIT_OF_VARS -DSAFEMALLOC -DPEDANTIC_SAFEMALLOC -O0 -g3 -gdwarf-2 -fno-implicit-templates -fno-exceptions -fno-rtti -D_P1003_1B_VISIBLE -DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ -DIGNORE_SIGHUP_SIGQUIT -DDONT_DECLARE_CXA_PURE_VIRTUAL -MT libpbxt_a-datalog_xt.o -MD -MP -MF ".deps/libpbxt_a-datalog_xt.Tpo" -c -o libpbxt_a-datalog_xt.o `test -f 'datalog_xt.cc' || echo './'`datalog_xt.cc; \ then mv -f ".deps/libpbxt_a-datalog_xt.Tpo" ".deps/libpbxt_a-datalog_xt.Po"; else rm -f ".deps/libpbxt_a-datalog_xt.Tpo"; exit 1; fi lock_xt.h: In function 'void xt_atomic_inc2(volatile u_int16_t*)': lock_xt.h:194: error: '__sync_fetch_and_add' was not declared in this scope lock_xt.h: In function 'void xt_atomic_dec2(volatile u_int16_t*)': lock_xt.h:209: error: '__sync_fetch_and_sub' was not declared in this scope lock_xt.h: At global scope: lock_xt.h:584: warning: 'struct XTRowLockList' only defines private constructors and has no friends lock_xt.h:640: warning: 'struct XTRowLocks' only defines private constructors and has no friends Is PBXT expected to work on MacOS X G5?

[Maria-discuss] why does UNION ALL use a temp table?
