Hi,

I applied the following patch from WindRiver:

NAME:GNU 4.1.2 Cumulative Patch for VxWorks 6.7 AND 6.8

(PowerPC)SUMMARY:Latest GNU 4.1.2 Cumulative Patch for VxWorks 6.7 and

6.8 (PowerPC)PRODUCT VERSION:GNU Tools 4.1.2TYPE:PatchDOWNLOADS:1.

cum.vxw6-4.1.2-ppc.2010aug12.zip

<https://support.windriver.com/olsPortal/download?docId=35427&contentId=021002_0001>DESCRIPTION:

I also recall an earlier patch.

So, something is different as I am not getting this problem on EPICS

R3.14.11

Thanks,
Ernest

Hi,

Latest snapshot of EPICS R3.14.12 does not compile under vxWorks 6.8
on the following target: vxWorks-ppc604

I think Jeff and I have already seen this compiler bug in vxWorks 6.6.
I will confirm that WRS has a compiler patch upstream
