- add org.eclipse.cdt.debug.application plugin which supports running CDT debugger as Eclipse application - add org.eclipse.cdt.debug.application.docs plugin which is the modified CDT docs - add org.eclipse.cdt.debug.standalone-feature which bundles the two aforementioned plugins - add org.eclipse.cdt.debug.standlone.source-feature Change-Id: I1a1ae855ab3912e678b7d9e3465e2fbbfe949e13 Reviewed-on: https://git.eclipse.org/r/25845 Reviewed-by: Jeff Johnston <jjohnstn@redhat.com> Tested-by: Jeff Johnston <jjohnstn@redhat.com>

<h1>Setting up include paths and macros for C/C++ indexer</h1>
|
|
|
|
<p>
|
|
The Stand-alone Debugger supports a number of actions based on the application's code such as code highlighting, navigation, content assist and static analysis.
|
|
Normally, C/C++ projects have to be configured to enjoy those features due to the fact that most real life C/C++ projects heavily depend on code outside of the project itself,
|
|
such as system headers or third party libraries. The C/C++ indexer needs to process those to provide an accurate index.
|
|
</p>
|
|
|
|
<p>The Stand-alone Debugger will try to discover include paths and preprocessor symbols automatically. This process is known as <a href="../concepts/cdt_c_scanner_discovery.htm">Scanner Discovery</a> or <b>Autodiscovery</b>.
|
|
This discovery of symbols is twofold.
|
|
The first method is that the Stand-alone Debugger will try to detect built-in compiler symbols and include paths running the compiler with special options and parse the output.
|
|
Another method that the Stand-alone Debugger employs is to analyze the output generated from a Makefile build. Since the
|
|
Stand-alone Debugger does not contain build support, this output must be saved externally and passed to the debugger either
|
|
on the command line using the <strong>-b</strong> option or else by specifying the build log using the <strong>File > New Executable...</strong>
|
|
dialog. Often, include paths are supplied to the compiler with -I options, and macros with -D options.
|
|
That relies on verbose build output of your build where all these options are actually printed by make.
|
|
</p>
|
|
|
|
<p>
|
|
<a href="../concepts/cdt_c_scanner_discovery.htm">Scanner Discovery</a> uses <strong>Language Settings Providers</strong> to find include paths and preprocessor symbols.
|
|
Language Settings Providers can be configured on project properties page "Preprocessor Include Paths, Macros, etc.", <a href="../reference/cdt_u_prop_general_sd_providers.htm">Providers tab</a> for a configuration
|
|
and on preference page <a href="../reference/cdt_u_pref_build_scanner_discovery.htm">C/C++ Preferences: Scanner Discovery</a> for shared providers.
|
|
</p>
|
|
<p>
|
|
If information retrieved by auto-discovery is insufficient a user can inspect discovered entries and enter additional include paths and macros manually
|
|
on the property page "Preprocessor Include Paths, Macros, etc.", <a href="../reference/cdt_u_prop_general_sd_entries.htm">Entries tab</a>.
