Hi,
I do face problems building MySQL 3.22.32 with gcc 3.2.2 on an Alpha-
DEC-OSF4 workstation.
CC="cc -pthread" CXX="cxx -pthread -O" ./configure --with-named-t
hread-libs="-lpthread -lmach -lexc -lc" --with-low-memory
Everything run's smoothly, till mysqld is to be build. The linker produces:
__cxa_pure_virtual
operator delete[](void*)
operator new[](unsigned long)
operator delete(void*)
operator new(unsigned long)
collect2: ld returned 1 exit status
gnumake[3]: *** [mysqld] Error 1
The linker option "-Wl,-y__cxa_pure_virtual" shows the .o files with this
symbol:
item.o: reference to external undefined __cxa_pure_virtual
item_sum.o: reference to external undefined __cxa_pure_virtual
item_func.o: reference to external undefined __cxa_pure_virtual
item_cmpfunc.o: reference to external undefined __cxa_pure_virtual
item_strfunc.o: reference to external undefined __cxa_pure_virtual
item_timefunc.o: reference to external undefined __cxa_pure_virtual
field.o: reference to external undefined __cxa_pure_virtual
sql_class.o: reference to external undefined __cxa_pure_virtual
procedure.o: reference to external undefined __cxa_pure_virtual
__cxa_pure_virtual
operator delete[](void*)
operator new[](unsigned long)
operator delete(void*)
operator new(unsigned long)
collect2: ld returned 1 exit status
What does that symbol mean? It does not show up when MySQL is
compiled with Linux and gcc. There are no definitions of new or delete in
the files listed. Can it possibly be an gcc problem?
The complete output when linking follows:
