3.1. General Compatibility 6.1.1¶
This section describes issues that may affect backward compatibility in the Connext suite in release 6.1.1.
See also Product-Specific Compatibility 6.1.1 for specific issues. For information about the RTPS versions supported for each Connext release, see Section 6.1.2.1.
3.1.1. Potential -fPIC flag issue when using static libraries in Linux and QNX if upgrading from 6.1.0¶
In 6.1.0, RTI no longer built Linux or QNX static libraries with the -fPIC flag
(whereas previously RTI did build with this flag). Therefore, in 6.1.0, you
could no longer link Linux or QNX static libraries with object files built
with the -fPIC flag.
Updating to 6.1.1 fixes this problem, because RTI builds Linux and QNX static
libraries with the -fPIC flag again in 6.1.1. Therefore:
If you are upgrading to 6.1.1 from a release before 6.1.0, you do not need to do anything.
If you are upgrading from 6.1.0 to 6.1.1 and you used Linux or QNX static libraries, you may need to change the way you build object files to use the
-fPICflag if you aren’t using the-fPICflag already.
