Re: Error while building EPICS base

[Ralph Lange <ralph.lange@gmx.de>]

Hello Thakur,

Why are you building 3.14.12.1? This release is more than four years old, lots of bugs have been fixed since then. The current release of the 3.14 (aka stable) series is 3.14.12.5. [1]
When sending such reports, please always include a description of the context (system, architecture, compiler) that you are using.

The particular bug you are seeing occurred when compiling EPICS Base on gcc newer than ~4.6.1. It was fixed in revision 12264 [2] of the 3.14 series, in August 2011.

If you do not have to support existing 3.14 drivers or IOC applications, I would suggest using the 3.15 (aka current) series of EPICS Base, which has a bunch of additional features.
Otherwise, please use the newest 3.14 release.

Cheers,
~Ralph
