Compile warning re casts in qpid/broker/SaslAuthenticator.cpp
-------------------------------------------------------------
Key: QPID-1154
URL: https://issues.apache.org/jira/browse/QPID-1154
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: M3
Environment: Red Hat Enterprise Linux 4, g++ 3.4.6
Reporter: Steve Huston
Priority: Minor
Attachments: qpid1154.diff
Compiling C++ broker yields the following warning which the build settings
promote to an error:
qpid/broker/SaslAuthenticator.cpp: In member function `void
qpid::broker::CyrusAuthenticator::processAuthenticationStep(int, const char*,
unsigned int)':
qpid/broker/SaslAuthenticator.cpp:237: warning: cast from `const void*' to
`char*' discards qualifiers from pointer target type
qpid/broker/SaslAuthenticator.cpp:239: warning: cast from `const void*' to
`char*' discards qualifiers from pointer target type
The attached patch resolves this by using multiple casts: cast const void* to
const char *, then const_cast to discard const.
