6.2.7. RTI Connext Micro¶
184.108.40.206. New Installation Procedure¶
Starting with release 3.0.0, Connext Micro is now distributed as an RTI Connext platform package. Connext Micro is installed as any other additional package from RTI. See Installing Connext. Connext Micro Security SDK is also now distributed as an RTI package. If you use it, you must install it on top of the Connext Micro package.
The Connext Micro User’s Manual is also available from the Help panel in RTI Launcher. You can find information about how to build Connext Micro in the Connext Micro User’s Manual.
In order to build and use Connext Micro, you must export the source outside the installation directory, since this directory is typically not writeable. In the RTI Launcher Utilities Tab, the “Copy Micro SDK” button is used for this purpose. Click the icon to open a dialog box where you can specify a destination folder.
After you export the source, build the Connext Micro libraries, then regenerate and recompile your code, as described in the installation section of the Connext Micro User’s Manual.
220.127.116.11. Change In Documentation¶
Starting with release 3.0.0, the Connext Micro User’s Manual is separate from the API Reference HTML documentation. The User’s Manual is now also available in PDF format. See also the Connext Micro Release Notes.
18.104.22.168. Application Binary Interface¶
Connext Micro does not provide Application Binary Interface (ABI) compatibility with previous versions of Connext Micro. Therefore, an application compiled using a version of Connext Micro prior to 3.0.0 must be recompiled when moving to a version of Connext Micro at or after 3.0.0.
Connext Micro is distributed in source form. In most cases, after compiling the Connext Micro libraries from the source, upgrading an application requires you to recompile your source using the new header files and link with the new libraries built from the Connext Micro source. In some cases, minor modifications to your application code might be required; any such changes are noted in this Migration Guide.
To upgrade to this release, first review the information in Section 6.1 and in Section 6.2 to see what modifications you may need to make to your application code. You may also want to see What’s New in 6.0.0, as well as the Connext Micro Release Notes 3.0.0, to see what is new or changed in this release. Then recompile your source using the new header files and link the new libraries.
The following Application Program Interfaces (APIs) have been changed or deprecated in 3.0.0. For new APIs, see the Connext Micro Release Notes 300.
22.214.171.124.1. Wchar and wstring language binding changes¶
See information about this change in Section 126.96.36.199.
188.8.131.52.2. RTI_CERT compilation flag not supported in this release¶
Connext Micro 3.0.x has not been through a certification process, and the
certifiable feature set has not been defined. For this reason, the
RTI_CERT compilation flag is not supported in this release. Support for
this flag will be introduced again when the certifiable feature set has been
184.108.40.206.3. Generated code compatibility¶
For Connext Micro applications defining types in IDL, XML, or XSD, moving from a previous Connext Micro version to Connext Micro 3.0.x requires code regeneration and recompilation.
You will need to regenerate the code for your application types using the
Code Generator shipped with this release. The regeneration process is
very simple; you only need to run the new version of Code Generator
using the original input IDL file. (You should see a message that says you
rtiddsgen version 3.0.1.) This process will regenerate the
header and source files, which can then be compiled along with the rest of
220.127.116.11.4. Default UDP socket buffer size on QNX changed to 64KB¶
In 3.0.0, the default socket buffer size on QNX has changed from 256KB to 64KB. You can change the default socket buffer sizes when you configure the UDP transport. Please refer to the Connext Micro User’s Manual for more information.
18.104.22.168. Connext Compatibility¶
Although Connext Micro 3.0.x interoperates with Connext 6.0.x, Connext Micro 2.4.11 and below does not communicate with any Connext 6.0.x product, due to a change in the RTPS version number introduced in 6.0.0. (See “Fixes Related to OMG Specification Compliance” in the RTI Connext Core Libraries Release Notes.) If you need Connext Micro 2.4.11 applications or below to communicate with Connext 6.0.x applications, see the article Workaround for discovery failure between RTI Connext Micro 2.4.11 and RTI Connext 6.0.0 or contact RTI Support at firstname.lastname@example.org.
This issue has been fixed in Connext Micro 2.4.12, which does communicate with a Connext 6.0.x product.
