Use of in-class static const variables in cms/DeliveryMode.h results in crash
while linking with --no-undefined option
----------------------------------------------------------------------------------------------------------------------
Key: AMQCPP-263
URL: https://issues.apache.org/activemq/browse/AMQCPP-263
Project: ActiveMQ C++ Client
Issue Type: Bug
Components: CMS Impl
Affects Versions: 3.0.1, 3.0, 2.2.6
Environment: - Linux Debian 5.0.1
- gcc 4.3.2
- ActiveMQ-CPP 2.2.6
Reporter: Romain Chanu
Assignee: Timothy Bish
Priority: Blocker
The constants variables defined in cms/DeliveryMode.h (i.e static const int
PERSISTENT = 0 and static const int NON_PERSISTENT = 1;) are not defined out
off the class.
In the following cases:
- If you try to take the address of this constant variable.
- You pass it to a function that takes a reference.
- When used with the tertiary operator ?
It results in a crash while linking ActiveMQ-CPP library with an application
using the linking option --no-undefined (GNU linker ld returns "undefined
references" for these two variables).
The variables should be defined as an enumeration (like the way it has been
done in cms/Session.h for the acknowledgment modes)
