<p class="section"><a name="_TocSectionIntro">1 Scope of the document</a></p>
<p>The document highlights the new features that were introduced in 
the New CDT Build System 4.0 from the ISV point of view. The document mostly 
focuses on the API details rather than on UI ones.</p>
<p>The document should be useful for ISVs willing to migrate or integrate their 
tool-chains to the CDT 4.0 and should serve as as a valuable addition to the the
<a href="../../migration_guides/4.0/migration_guide_40.html">Migration Guide 
document</a>, although despite of the
<a href="../../migration_guides/4.0/migration_guide_40.html">Migration Guide</a> 
it mostly focuses on highlighting feature details rather than on the migration 
problems. Please also refer to the

<p class="subsection"><a name="_TocSectionUIModel_1">2.1 Standard and Managed 
Build System incorporation</a></p>
<p>In CDT 4.0 Standard and Managed Build Systems are incorporated into one CDT 
Build System. This allows all Standard Make features to be used for the Managed 
Build Projects and vice a versa and also provides one common API and UI 
interface for the build settings.</p>
<p>The CDT Build System is created based upon the Managed Build System 
functionality (org.eclipse.cdt.managedbuilder.core and 
org.eclipse.cdt.managedbuilder.ui plug-ins). So all the API that were used for 
the Managed Build Projects in the CDT 3.x becomes valid for the Makefile 
Projects in the 4.0, i.e</p>
<p style="margin-top: 0; margin-bottom: 0">The <b>
org.eclipse.cdt.managedbuilder.core.buildDefinitions</b> extension point serves 
as an entry-point for the tool integration into the Build System.</p>
<p style="margin-top: 0; margin-bottom: 0">The <b>
org.eclipse.cdt.managedbuilder.core.ManagedBuildManager</b> class serves as an 
entry-point for accessing/manipulating the Build Settings information.</p>
<p>From the API point of view there is no principal difference between 
the Makefile and Managed Build Projects. From the Build System perspective the 
difference between the &quot;Makefile&quot; and the &quot;Managed&quot; modes is that in case of the 
Managed build the makefile generation is performed (or the Internal Builder is 
used), while for the Makefile Build no makefile generation is done, so it is 
expected that the makefile is supplied by the user. Switching between the 
Managed and the Makefile modes is actually switching the Makefile generation 
either on or off.</p>
<p>A toolChain, tool, builder definitions now have have the &quot;supportsManagedBuild&quot; 
property to specify whether or not the managed build is supported for the given 
object. </p>

Model schema</a></p>
<p class="MsoNormal" style="margin-top:6.0pt">The figure below shows a UML model 
of the schema elements.&nbsp; It is simplified by leaving out the fact that the 
configuration, toolChain, tool, targetPlatform, and builder definition elements 
can be defined at the top level in a manifest file.</p>

<p class="subsection"><a name="_TocSectionUIModel_2">2.2 New New Project Wizard</a></p>
<p>The CDT 4.0 presents a new New Project Wizard. This section primarily 
focusing and describing the ways a tool-integrator can influence on how his/her tool-chains and project types 
are presented in the wizard on the first wizard page. Please refer to the &quot;New 
Project Wizard&quot; user description for more detail on the New Project Wizard UI.</p>
<p>The first wizard page presents the wizard allows user to select a project 
type and tool-chain(s) to be used with the project type.</p>
<p>&nbsp;</p>
<p><img border="0" src="../../migration_guides/4.0/migrat1.gif"></p>
<p><b>Presenting project-types and tool-chains in the New Project Wizard</b></p>
<p>A tool-integrator has two options of presenting his project-types in the 
wizard.</p>
<ol>
	<li>Define a new custom Project Type entry.</li>
	<li>Use the general project type entries mechanism.</li>
</ol>
<p><b><font color="#FF0000">NOTE:</font></b>&nbsp; The new New Project Wizard now 
	operates with tool-chains allowing to select the tool-chain(s) to be used on 
	project creation. Thus it is 
	required that all toolChain/tool/builder build definitions representing 
	different tool-chains/tools/builders must have different names as well as toolChain/tool/builder build definitions representing one and the same 
	tool-chain/tool/builder must have identical names.</p>
<p class="MsoNormal" style="margin-top:0; margin-bottom:0"><b>&nbsp;&nbsp;&nbsp; 
	Example:</b> to illustrate the above requirement here is how this is handled 
	in the gnu tool-chain definitions:</p>
<p class="MsoNormal" style="margin-top:0; margin-bottom:0">&nbsp;&nbsp;&nbsp; 
	The gnu plug-in contains the gcc linker tool on Linux is defined as</p>
<p class="MsoNormal" style="margin-top:0; margin-bottom:0">&nbsp;&nbsp;&nbsp;&nbsp; 
	&lt;tool<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; natureFilter=&quot;cnature&quot;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; name=&quot;%ToolName.linker.gnu.c&quot;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outputFlag=&quot;-o&quot;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; command=&quot;gcc&quot;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; id=&quot;cdt.managedbuild.tool.gnu.c.linker&quot;</p>
<p class="MsoNormal" style="margin-top:0pt; margin-bottom:0">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
	...</p>
<p class="MsoNormal" style="margin-top:0pt; margin-bottom:0">&nbsp;&nbsp;&nbsp;
	</p>
<p class="MsoNormal" style="margin-top:0pt; margin-bottom:0">&nbsp;&nbsp;&nbsp; 
	At the same time the gnu tool-chain definitions refers to the gcc linker by 
	defining a new tool as a super-class of the &quot;cdt.managedbuild.tool.gnu.c.linker&quot; 
	tool</p>
<p class="MsoNormal" style="margin-top:6.0pt">&nbsp;&nbsp;&nbsp;&nbsp; &lt;tool<br>&nbsp;&nbsp;&nbsp; id=&quot;cdt.managedbuild.tool.gnu.c.linker.base&quot;<br>&nbsp;&nbsp;&nbsp; superClass=&quot;cdt.managedbuild.tool.gnu.c.linker&quot;&gt;</p>
<p class="MsoNormal" style="margin-top:6.0pt">...</p>
<p class="MsoNormal" style="margin-top:6.0pt">Both tool definitions listed 
	above are actually treated as two different tools by the Build System, while 
	both of them refer to one and&nbsp; the same &quot;gcc&quot; executable. To make the 
	build system aware that both tool definitions refer to one and the same tool/executable 
	it is required that both tool definitions specify one and the same name. In 
	the above sample the tool of id=&quot;cdt.managedbuild.tool.gnu.c.linker.base&quot; 
	does not specify any name thus making the name to be inherited from the 
	super-class tool, so both tools have the same name.</p>
<p class="MsoNormal" style="margin-top:6.0pt">On the other hand the cygwin 
	gcc linker is defined as </p>
<p class="MsoNormal" style="margin-top:6.0pt">&nbsp;&lt;tool<br>id=&quot;cdt.managedbuild.tool.gnu.c.linker.cygwin&quot;<br>name=&quot;%ToolName.linker.cygwin.gnu.c&quot;<br>superClass=&quot;cdt.managedbuild.tool.gnu.c.linker&quot;&gt;<br>...</p>
<p class="MsoNormal" style="margin-top:6.0pt">although the tool definitions 
	is defined as a super-class of the linux gcc linker, it refers to the 
	different tool(executable) than the Linux linker definition. The cygwin 
	linker definition specifies the name=&quot;%ToolName.linker.cygwin.gnu.c&quot; that 
	differs from the one defined by the Linux gcc linker.</p>
<p><b>Defining new Project Type entries</b></p>
<p>In case a tool-integrator is willing his/her project type to be displayed as 
separate entries with custom names, his project-type definition must specify a 
&quot;name&quot; property for the project-type, e.g.</p>
<p><img border="0" src="whats_3.gif"></p>
<p>When the project type entry is selected in the wizard the &quot;Toolchain:&quot; 
pane will display the list of tool-chains defined/associated with the project type</p>
<p><b>Using general project type entries</b></p>
<p>The &quot;general project types&quot; mechanism allows grouping multiple project 
types/tool-chains under one project-type entry thus ensuring the compactness of 
the project-type information and ensuring a common user experience across 
different tool-chains and integrations. When the general project type entry is selected the 
&quot;ToolChains:&quot; pane will list all tool-chains contributed from different project 
types allowing user to select the tool-chain to be used with the given 
project-type.</p>
<p><b>What are the general project type entries?</b></p>
<p>The general project type entries mechanism is made based upon the new Build 
Properties mechanism introduces in the new CDT Build System. Each general project type 
entry is a value of the &quot;buildArtefactType&quot; property which represents the build 
artifact type. The New Project wizard searches for the tool-chains supporting 
each of the defined build artifact types and displays them in the &quot;ToolChains:&quot; 
pane for each of the build artifact type.</p>
<p>CDT pre-defines the following values of the build artifact type property:</p>
<p>&quot;org.eclipse.cdt.build.core.buildArtefactType.exe&quot; - to represent executable</p>
<p>&quot;org.eclipse.cdt.build.core.buildArtefactType.staticLib&quot; - to represent 
static library</p>
<p>&quot;org.eclipse.cdt.build.core.buildArtefactType.sharedLib&quot; - to represent 
shared library</p>
<p>ISVs can define their own custom build artifact values by contributing to the 
org.eclipse.cdt.managedbuilder.core.buildProperties extension point.</p>
<p>See the &quot;Build Properties&quot; section for more detail on the Build Properties 
mechanism.</p>
<p><b>Contributing to the general project type entries</b></p>
<p>The minimal steps needed to specify that the general project type entry should be used, a project-type 
definition should specify the &quot;buildArtefact&quot; attribute and assign it to one of 
the values of the buildArtefactType build property, e.g.</p>
<p>&nbsp;&lt;projectType <br>
&nbsp;&nbsp;&nbsp; buildArtefactType=&quot;org.eclipse.cdt.build.core.buildArtefactType.exe&quot;<br>
&nbsp;&nbsp;&nbsp; id=&quot;cdt.managedbuild.target.gnu.exe&quot;&gt;</p>
<p>&nbsp;&nbsp; ...</p>

<p>&nbsp;</p>
<p class="subsection"><a name="_TocSectionUIModel_3">2.3 Multi-configuration support for makefile 
projects</a></p>
<p>The new CDT Build System supports multiple configuration settings. This is 
applicable for the Managed and Makefile projects now. As with the Managed 
projects the org.eclipse.cdt.managedbuilder.core.IConfiguration interface serves 
as a holder of the configuration settings.</p>
<p>&nbsp;</p>
<p class="subsection"><a name="_TocSectionUIModel_4">2.4 Tool-chain support for makefile projects</a></p>
<p>The new CDT Build System provider the notion of the tool-chain/tool/builder 
definitions. The tool-chain are used for the Makefile projects as 
holders/profiles containing/grouping different settings applicable for the given 
tool-chain thus allowing the project seyttings to be automatically configured 
based upon the tool-chain being used. This includes adjusting error parser, 
binary parser settings, scanner discovery profile settings, etc.</p>
<p class="subsection"><a name="_TocSectionUIModel_5">2.5 Per-folder settings</a></p>
<p>It is now possible to specify custom settings on the per-folder&nbsp; level. 
It is as well possible to exclude folders from build. A new interface folderInfo 
schema element is presented. See the buildDefinitions model above for more 
detail.</p>
<p class="subsection"><a name="_TocSectionUIModel_6">2.6 Internal Builder</a></p>
<p style="margin-top: 0; margin-bottom: 0">It is now possible to use the Internal Builder in the tool-chain definitions. 
The Internal Builder is treated as a regular builder by the Build System. To 
associate the Internal Builder with the tool-chain the tool-chain should define 
the builder specifying the Internal Builder as its super-class via a builder#superClass 
attribute. The Internal Builder id is &quot;org.eclipse.cdt.build.core.internal.builder&quot;. 
E.g.</p>

<p class="subsection"><a name="_TocSectionUIModel_7">2.7 Customized configuration builds</a></p>
<p style="margin-top: 0; margin-bottom: 0">It is now possible to initiate the 
project build that will use customized settings that differ from those of the 
currently active configuration.</p>
<p style="margin-top: 0; margin-bottom: 0">The following modes are supported:</p>
<ol>
	<li>
	<p style="margin-top: 0; margin-bottom: 0">Building any number of project 
	build configurations with one build request</p></li>
	<li>
	<p style="margin-top: 0; margin-bottom: 0">Building any number of 
	configurations with builder settings customized</p></li>
</ol>
<p style="margin-top: 0; margin-bottom: 0">This functionality can be used 
programmatically via the 
org.eclipse.cdt.managedbuilder.core.ManagedBuildManager.buildConfigurations(...) 
methods.</p>
<p style="margin-top: 0; margin-bottom: 0">It is also accessible in UI via the 
&quot;Build Configurations&quot; -&gt; &quot;Build&quot; project context menu.</p>
<p style="margin-top: 0; margin-bottom: 0">&nbsp;</p>
<p style="margin-top: 0; margin-bottom: 0">NOTE: For Managed builds (makefiles 
are generated automatically) this functionality works only in case the buildfile 
generator implements the 
org.eclipse.cdt.managedbuilder.makegen.IManagedBuilderMakefileGenerator2. This 
interface extends the old IManagedBuilderMakefileGenerator by defining a new 
initialize() method which accepts IConfiguration and IBuilder rather than 
IManagedBuildInfo thus removing an assumption that only active configuration can 
be used for building.</p>
<p style="margin-top: 0; margin-bottom: 0">The default GnuMakefileGenerator 
supplied with the CDT now implements this interface, so in case the builder is 
using this default implementation, no changes are needed.</p>

Projects</a></p>

<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0"><span lang="EN-US">
The Build Properties mechanism allows defining a set of properties along with 
the possible property values for each property.</span></p>
<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">It is possible to 
associate some set of properties with the configuration/project type.</p>
<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">The tool-chains and 
tools in their turn are allowed to specify the set of supported properties and 
their supported values for those properties.</p>
<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">&nbsp;</p>
<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">Given these 
capabilities the Build Properties mechanism is used to facilitate the following 
functionality:</p>
<ol>
	<li>
	<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">The New Project 
	Wizard is now now creating the set of &quot;general&quot; project type entries based 
	upon the available values for the &quot;org.eclipse.cdt.build.core.buildArtefactType&quot; 
	build property and allows associating tool-chains with those project type 
	entries given the information on the build artefact type values supported by 
	the tool-chains and defined for the project types.</li>
	<li>
	<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">With the 
	tool-chain modification functionality <span lang="EN-US">tool-chains, tools 
	and builders can use the build properties mechanism to adjust their settings 
	(e.g. option values for tools, etc. ) using enablement expressions 
	mechanism. This allows easy tool-chain/tool/builder switching without the 
	necessity to implement a converter. Having this mechanism it is possible to 
	define tools whose default option values will depend on the set build 
	properties associated with the configuration. Thus it is possible to have 
	one tool-chain definition whose values will be automatically adjusted 
	depending on whether the tool-chain is being used to create executable or 
	library, etc. or depending on whether the tool-chain is used in the 
	&quot;release&quot; or &quot;debug&quot; build, etc.</span></li>
	<li>
	<p class="MsoNormal" style="margin-top: 0; margin-bottom: 0">It is now 
	possible to change the build artifact type of the already created project by 
	changing the value of the buildArtefactType property in case the tool-chain 
	supports that.</li>
