Re: WireSet missing with 3.14.10

[Dehong Zhang <dhzhang@fnal.gov>]

Hi Andrew,

Thank you very much.  Sorry to bother you again.

Guess my problem is with building the base.

We need the "vxWorks6-mv5100" architecture, but the base package does not
have it.  So I copied from our working v3_14_8 the following 3 files to configure/os
CONFIG.Common.vxWorks6-mv5100
CONFIG_SITE.linux-x86_64.vxWorks6-mv5100
CONFIG_SITE.linux-x86.vxWorks6-mv5100

And edited 
CONFIG_SITE.Common.vxWorksCommon
to un-comment "VXWORKS_VERSION = 6.1" -- as you suggested, and commented
out the "WIND_BASE = ..." line because we have defined this variable.

Also edited "CONFIG.Common.vxWorks6Common" to comment out the
"export WIND_BASE = $(VX_DIR)" line -- so it is not going to override the
original WIND_BASE.  Hopefully this VX_DIR is the same so this should have no
effect.

When I build the base, there is no complains, only a few warnings.  But if i do
grep WireSet */*/*/*   in the top directory of the base, I will get something 
like
Binary file src/softIoc/O.vxWorks6-mv5100/softIoc matches
Binary file src/softIoc/O.vxWorks6-mv5100/softIoc.munch matches
src/softIoc/O.vxWorks6-mv5100/softIoc.nm:         U _Z7WireSetIfEvRKT_Ph
src/softIoc/O.vxWorks6-mv5100/softIoc.nm:         U _Z7WireSetIiEvRKT_Ph
src/softIoc/O.vxWorks6-mv5100/softIoc.nm:         U _Z7WireSetIsEvRKT_Ph

Guess the base is not built ok.  Could you please help to find a set of support files
for our vxWorks6-mv5100?  And advice on how to change other config settings?

Sorry to be vague!  I am not familiar with the epics build structure.

Thank you again, best regards,
Dehong
