What's new in QNX SDP?
This minor update to QNX SDP 8.0 focuses primarily on addressing a set of issues identified within several QNX OS components, to improve overall stability and reliability.
Installing QNX SDP
To use QNX SDP 8.0.4, you need to have QNX Software Center 2.0.4 or later. For
information about installing and using this other product, refer to the Install and launch the QNX Software Center
chapter in the QNX
Software Center User's Guide.
To install the QNX SDP 8.0.4 packages as a new baseline product, open the QNX Software
Center and click Add Installation on the left to launch the
New Installation Wizard. In the first dialog, expand
QNX Software Development Platform 8.0 and select QNX
Software Development Platform 8.0.4. Follow the prompts (i.e., the
Next and Install buttons) to perform the
installation. Select any of the options from the Update Policy
dropdown. For more information, refer to the Install the QNX Software Development Platform
chapter in the QNX
Software Center User's Guide.
To update your existing QNX SDP 8.0.3 installation to version 8.0.4, use the provided patch set. To install the patch set, open the QNX Software Center, select the installation you want to update in the Active Installation dropdown on the Welcome page and click Install New Packages. The QNX SDP 8.0.4 patch set is found under Available -> QNX Software Development Platform - Minor Release -> Patchset.
After the installation, you can access information about its results under Installed -> QNX Software Development Platform -> Software Development Platform.
To access the contents of this release, go to the All tab and search for GA8.0.4. For each listed package, right-click, choose Properties, and then click Package Contents. Some of the packages may contain references to contained packages (or subpackages) instead of files, in which case the contents page displays a note that says so. To access the list of subpackages, right-click the package, choose Properties, then click Package Dependencies. Because the baseline OS product has many inter-package dependencies, sometimes you have to go through multiple levels of subpackages to access the included files.
You can also obtain the maturity statuses of files by generating a manifest
report. For more information, refer to the Manifest Reports & File Lookup
chapter of the QNX Software
Center User's Guide.
Each package has its maturity level. You can learn
this by right-clicking the package, choosing Properties, then
clicking General Information. In the Legal and
Regulatory Information panel, there's a Status
field. For details about the possible values of this field, refer to Package
status
in the Deploy licenses to users
section in the QNX Software Center User's
Guide.
Debug information for shipped binaries
The QNX SDP target binaries are generated with debug information (-g), with the debug form of the binary stored in a separate binaryName.sym file. The non-sym form is stripped of the debug and .ident information (use -s works only on files containing the .ident section).
Most target packages include debug information (.sym files). The binaries and their .sym files are linked, so gdb understands where to find the symbol data. There's no need to store .sym files for the binaries on a target.
If the debug symbols are especially large, there might be a separate debug package in the QNX Software Center. To install debug symbols in this case, select your installation from the toolbar, then go to the Advanced tab. Click Edit Installation Properties. In the property dialog that opens, ensure that the Install debug symbols checkbox is selected (this box is selected by default). Click OK.
If you decide to not install the debug information but later want it, you can right-click a package and choose Install debug symbols.
Discontinued and deprecated items
For documentation on all items that are no longer shipped in this release or will be removed in a future release, refer to the QNX Software Development Platform 8.0: Discontinuation and Deprecation Notice.
Experimental items
Some experimental items are implemented in the packages of the baseline product. This means these items are installed when you install QNX SDP and, hence, there's nothing else you must do to be able to use them. Other experimental items are contained in their own packages that aren't installed when you install QNX SDP. To locate and install these packages so you can use the items they contain, go to the Available tab in QNX Software Center and search for part or all of the package name. Then, click the package in the search results and then the Install button in the bottom right corner.
The table that follows lists the experimental items by functional area and indicates whether each one is contained in an additional package that must be installed separately.
