Subject: Generating a loadable module for cexp (epics 3.14.12.3)
From: Sue Witherspoon <[email protected]>

Hi,
I've been using cexp for rtems 4.9.2, epics version 3.14.11 for some time now with little problem. Recently, I tried rebuilding my application using epics version 3.14.12.3. The build was successful with no errors but when I load the cexp module I get
pages of load errors ( ...already exists...). See below.
What changed in the build process? Is there a fix for it? I did have a similar problem when I added the 'devIocStats' library to my epics 3.14.11 application but adding the following to my Makefile alleviated the problem.

Going to probe for Ethernet chips when initializing networking:
(supported are 3c509 (ISA), 3c90x (PCI) and eepro100 (PCI) variants).
NOTES:
- Initializing a 3c90x may take a LONG time (~1min); PLUS: it NEEDS media
    autonegotiation!
  - A BOOTP/DHCP server must supply my IF configuration
