This is the New & Noteworthy page for CDT 9.3 which is part of the Eclipse Oxygen release of June 2017
|C++11 "auto" variables|| For variables whose type is declared with the C++11 |
|Following includes in inactive code paths|| Open Declaration can now follow |
|Navigation to forward declaration of class template|| Open Declaration now supports navigation from the definition of a class template to its forward declaration.
This can be useful in cases where some of the class template's template parameter have default arguments, as the default arguments may only be declared at the forward declaration.
|Open Declaration in assembly files||The Open Declaration action is now supported in assembly files.|
|Completion of member functions when taking the address|| After a classname qualifier such as |
However, sometimes the address of a nonstatic method is taken, usually to be passed as a callback. CDT now recognizes the

|Included files with no file extension|| CDT now offers completion proposals for files with files extensions other than the usual C/C++ header file extensions (such as |
To avoid polluting content assist proposals with irrelevant files, in cases where a directory contains both files with the usual C/C++ header extensions, and other files, proposals for files in the first category are shown first.
|Enhanced parameter hints||CDT's parameter hints have been enhanced (bug 461680). They now show the full signature of the function being called, including its return type, containing class (if it's a method), and whether it's virtual.|
|Constructor completion with uniform initialization syntax||
CDT's content assist now recognizes constructor calls that use the C++11 uniform initialization syntax and offers completion proposals for the constructor(s).
|Enclosing definition of macro reference||
In the Search view, the enclosing definition (function and class if applicable) is now shown for macro references the way it is for references to other entities (bug 508216).

|Folding of Comments Improvements||
Some improvements have been made to folding comments. Documentation comments can now fold together when using /// style comments. In addition new preferences on initial folding state of comments have been provided.
GCC Build Quick-fixes
Quick fixes have been added for a variety of build errors generated by the gcc compiler. Such fixes include:
|Support for -fdiagnostics-parseable-fixits||
Clang and gcc 7 have support for generating fix-it suggestions for various compiler errors. When the -fdiagnostics-parseable-fixits option is specified for the build, CDT is able to parse these fix-it messages and generate quick-fixes for them.
|More accurate binding resolution||
This release fixes a long-standing issue where the indexer would resolve names in a source file that referenced entities that did not have a declaration in any file included by that source file, only in other files in the project.
As a result of this change, the set of semantic errors produced by the indexer should more closely resemble what an actual compiler produces.
Another positive effect is, that CODAN now reports "unresolved symbol" errors when a symbol is used but the corresponding #include was not added. This may help fixing such issues (potentially by using "organize includes") before invoking the compiler, thus saving time.
|Exposing the CDT version number for feature-testing||
CDT defines the

|C++14 Language Support|
|Prebuild task and parallel make||
Pre-build tasks and parallel make is now working together. Pre-build tasks can be used to generate header and source files as the pre-build task is now guaranteed to complete before any source code is built.
Also, the build targets under Project Settings -> C/C++ Build -> Behavior -> Workbench Build Behavior is respected and works the same for projects both with and without pre-build tasks.
|Build console speed up||
Doing builds in CDT are now significantly faster when there is a lot of output, warnings, and/or errors.
The benefits of this improvement are:
This solves (bug 314428).
|.SECONDARY removed from generated Makefiles||
In this release of CDT .SECONDARY: with no dependencies has been removed from the generated Makefiles. .SECONDARY with no dependencies can allow a build to succeed even if some dependencies are required. In the unlikely event that a project was depending on such behaviour the behaviour can be restored by creating a makefile.targets in the root of the project with .SECONDARY: as the file's contents. See the bug for more details.
This solves (bug 516813).
|Support to extend the toolbar of the Debugger Console pages||
Just like the standard Console view, the Debugger Console view now allows the use of the Console Page Participants extension point. By using this extension, extenders can add buttons to the toolbar of the different pages of the Debugger Console view. An example of such additions can be found in org.eclipse.cdt.examples.dsf.gdb/GdbExtendedConsolePageParticipant.java and has been copied below.
<extension point="org.eclipse.ui.console.consolePageParticipants"> <consolePageParticipant class="org.eclipse.cdt.examples.dsf.gdb.ui.console.GdbExtendedConsolePageParticipant" id="org.eclipse.cdt.examples.dsf.gdb.debuggerConsolePageParticipant"> <enablement> <and> <instanceof value="org.eclipse.cdt.debug.ui.debuggerconsole.IDebuggerConsole"/> <!-- The below check only works with the Debugger Console view and not the standard console view. But that is ok since this contribution is for the Debugger Console views only. --> <with variable="org.eclipse.core.runtime.Platform"> <test property="org.eclipse.core.runtime.bundleState" args="org.eclipse.cdt.examples.dsf.gdb" value="ACTIVE"> </test> </with> </and> </enablement> </consolePageParticipant> </extension>
Furthermore, a new method was added to provide access to the full console widget. This allows to modify or extend the behaviour of the full GDB console. The method in question is GdbFullCliConsolePage#getTerminalViewControl() which returns an ITerminalViewControl. ConsolePageParticipants are provided with the console page in their init() method; they can then cast it to GdbFullCliConsolePage to access the ITerminalViewControl.
This support was a contribution from Stephen Flynn from Dell-EMC.
Source not found editor modifications
|User have now 3 choices to display the source not found editor :||
- Source you were jumping into is not found: - Function name known but can't find its source: - Unknown function name
|Launch Group now part of Eclipse Platform :||
The Launch Group feature of CDT has been promoted to the Eclipse Platform. The version in CDT has been deprecated and will be removed in a future version.
|Support for Arduino|
