Hi Janet,

I don't have any system with a gcc 4 running - it's all gcc 3.

I do *NOT* have 3.14.7 in my mrkSoftTest/configure/RELEASE.

I intentionally create 2 -Wl options, because here the location of Base

differs between development and production systems. To be able to run

the exe on both worlds, I'm compiling both paths into the binaries: the

local - for development, and the generic - for the production systems.

Is it illegal to use two compiled-in paths? From first glance I wouldn't

see why.

Does the build system rely on just one path being defined? If so: Is

that limitation justified?

Hi Ralph,

Is it possible that your R3.14.7 EPICS base on linux was built with

gcc version 3 and you are now building with gcc version 4?

Why do you have R3.14.7 in your mrkSoftTest/configure/RELEASE file?

You shouldn't have 2 -Wl options for EPICS base.

I don't see any changes in mrkSoftTest, though. Strange. I'm pretty

sure you know faster than me what's wrong ...
