Hello 王林,

You need full C++ support in your vxWorks kernel. This is not the default!

I have:
#define INCLUDE_CTORS_DTORS         /* include constructors/destructors */
#define INCLUDE_CPLUS               /* include C++ support */
#define INCLUDE_CPLUS_IOSTREAMS     /* include basic iostreams classes */
#define INCLUDE_CPLUS_STL           /* include Standard Template Library
core */
#define INCLUDE_CPLUS_STRING        /* include string class */
#define INCLUDE_CPLUS_STRING_IO     /* include i/o for string class */
#define INCLUDE_CPLUS_COMPLEX       /* include complex number class */
#define INCLUDE_CPLUS_COMPLEX_IO    /* include i/o for complex number
class */
#define INCLUDE_CPLUS_IOSTREAMS_FULL/* include all of iostreams */

You probably don't need *COMPLEX* for EPICS but better have the rest.

Dirk
