synApps and external sequencer installation

[Luca Cavalli <LCavalli@cgspace.it>]

Dear all,

I have a IOC using synApps 5.8 (for the "transform" record) and sequencer 2.2.4.
I cloned my IOC from XXX reference IOC in synApps as suggested by documentation.
If I set SNCSEQ variable pointing to my sequencer 2.2.4 installation on top of
my IOC RELEASE file, it gets ignored and my state machines are compiled with the
sequencer included in synApps (2.2.1). If I set SNCSEQ at the bottom of RELEASE,
this error message is printed and compilation stops:

Setting SNCSEQ in my src/Makefile works, but is it the correct approach?
Is it possible to make synApps (and its sequencer installation used internally)
and an external sequencer installation coexist?


Thanks for your help,

Luca
