Hi Bruce,
Thanks for the feedback.  I did attempt putting these modifications
by adding SITE_CONFIG.Common.linux-686 and pointing to it from
CONFIG in the StreamDevice/configure files and also by modifying
the file in base/configuration/os.  Unfortunately neither of these worked
for me.  As you can see, the correct library doesn't show up in the
linking phase:

Of course, I may have not been following your suggestions sufficiently accurately so
please feel free to correct me.
Thank you,
Pierrick

Try this in your configure/CONFIG_SITE.Common.linux-686 file:

PCRE_LIB=/usr/local/products/elsd/conc405x/linux-3.16.7_generic/output/staging/usr/lib
PCRE_INCLUDE=/usr/local/products/elsd/conc405x/linux-3.16.7_generic/output/staging/usr/include

It'll also help to add this line:
LIB_INSTALL += $(wildcard $(PCRE_LIB)/lib*)

This last line will install all the pcre libs in your streamdevice lib/linux-686 dir
which will allow your IOC's to link w/o needing to also define PCRE_LIB.

Cheers,
