Hi Andrew,

My initial posting was about a new Pentium4 Dual Core IOC.

However, I was not running an SMP vxWorks Image.

So, my original problem must be related to a change in the memLib API

from Windriver,

I will investigate that a bit more based on the information from Jeff.

Meanwhile, I decided to  go ahead and build a SMP vxWorks image.   :)

You are right, changes are definitely needed

I can't even run the libCom Tests since routines like "intLock" and

"taskLock" are not available.

Now, we must use spinlocks and other atomic routines in the vxWorks SMP API

I agree an excellent codeathon activity :-)

You must be one of the first sites running EPICS on the new symmetric
multiprocessing (SMP) vxWorks!

Ernest, if you have more than one core enabled I can _guarantee_ that your IOC

is not going to run properly. Our vxWorks OSD code is not ready for SMP

operation yet, it needs someone to go through it with a fine tooth-comb, which

might be a good Codeathon project for one of your guys.

Must I throw the  "-mlong"  flag?
I thought that was only for the PowerPC architecture.?

It's not going to be as simple as that.

Please try running the libCom test suite on this CPU first:
    cd "/path/to/epics/base"
    ld 0,0, "bin/vxWorks-xxx/vxTestHarness.munch"
    epicsRunLibComTests

Any test failures in the results should give a few ideas of places that will

need a closer look.
