Re: Does EPICS Base support multi-thread on vxWorks 6.3?

[lorna.zhang@ni.com]

Finally, I'm able to build my own vxTestHarness.munch.
I put it onto my vxWorks system, load it, and run the command epicsThreadPrivateTest,
all 5 tests passed.

Now I have no idea what has caused our
problem :(

Actually we DO use EPICS build system,
to build the static libraries (.a files on vxWorks). And then we link all
the static libraries that we need into a single dynamic library (.o file
on vxWorks). I'm not sure if there's munching stuff happening during the
linking process. Could that be the issue?

Thanks,

Lorna Zhang

Hi Lorna,

Do you use C++ in any of the other code you are running on vxWorks?  If
EPICS 
is the only source of C++ code in your system then your build system may
not 
be properly handling the initialization code for C++ static constructors
and 
destructors, which is what the munch process is for.  This is documented
by 
Wind River in their VxWorks Kernel Programmers Guide; for vxWorks 6.3 see
section 11.5 "Downloadable Kernel C++ Modules".

I don't have access to vxWorks 6.3, and I don't think any binary I build
using 
either vxWorks 5.5.2 or 6.8 would work properly on your version.  You
will 
have to build EPICS Base yourself using our build system.  You can
find 
instructions on the tools you need to do that on Windows at
