Hello Stefen,

I found _ZNSt9exceptionD2E (or demangled std::exception::~exception) in

libstdc++.a in vxWorks 6.2, 6.3, 6.4, 6.6 and 6.7 (all vxWorks 6 I

have). So If you include full C++ support in vxWorks, you should have it.

__gxx_personality_v0 is also in libstdc++.a but only in vxWorks 6.7.

VxWorks 6.2 - 6.6 have __gxx_personality_sj0.

So If you have vxWorks 6.7 (or maybe higher) with C++ included, you

should have the symbols.

Hi Stefen,

That basically says that your app1 makes use use of
std::exception::~exception and __gxx_personality_ but they are neither
defined in your code nor already loaded in in the system.

This is vxWorks, right?

Do you have full C++ support included in your vxWorks?

Hello all,

While running EPICS startup script st.cmd on vxWorks for an app that was
made successfully, I am getting following error :

Any clues what might me wrong ?

Thanks,
