HI ,
I got a C SRC code that i want to have it build in eclipse environment , this SRC was build with in a different environment that uses some kind of batch files to build them all.
I want to ramp up a complete eclipse development environment to build this entire SRC code , and i have no ideas where to begin at all.
What are the steps that i need to do ?
Thanks.
Tom

to the best of my knowledge there is two solutions.
1- you can create an eclipse headless plug-in and then run eclipse from the command line. Notice that when running eclipse from the command line you still needs to open an workspace and create a C project and link its source folder with the SRC code location. If you wish I can provide you with an example.
2- you can run CDT outside eclipse. To do that you needs those jar files (any version is ok):
org.eclipse.cdt.core_5.9.1.201502131403.jar
org.eclipse.cdt.ui_5.9.0.201502131403.jar
org.eclipse.core.contenttype_3.4.200.v20140207-1251.jar
org.eclipse.core.jobs_3.6.1.v20141014-1248.jar
org.eclipse.core.resources_3.9.1.v20140825-1431.jar
org.eclipse.core.runtime_3.10.0.v20140318-2214.jar
org.eclipse.equinox.common_3.6.200.v20130402-1505.jar
org.eclipse.equinox.preferences_3.5.200.v20140224-1527.jar
org.eclipse.osgi_3.10.2.v20150203-1939.jar
but in this case you have to manage the included files manually. An example:

You have to do something like this. but c project instead of java project. Also info about headless eclipse plugins you can find with a google search.
public class ConsoleApp implements IApplication {
@Override
public Object start(IApplicationContext context) {
try {
String[] args = (String[]) context.getArguments().get(
"application.args");
Platform.getBundle("AnyBundleYouNeedsToStart").start();
} catch (Exception e) {
e.printStackTrace();
}
importSourceCode("path to source");
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IProject project = root.getProject("Temp Project");
try {
project.delete(true, null);
} catch (CoreException e1) {
}
return IApplication.EXIT_OK;
}
@Override
public void stop() {
}
private static String importSourceCode(String absolutePathToDocument) {
IProject project = null;
String srcFolderLocationInTheProject = "src";
String projectName = "Temp Project";
try {
// Create a project
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
project = root.getProject(projectName);
if (project.exists()){
project.delete(true, null);
}
project.create(null);
project.open(null);
// Because we need a java project, we have to set the Java nature to
// the created project
IProjectDescription description = project.getDescription();
description.setNatureIds(new String[] { JavaCore.NATURE_ID });
project.setDescription(description, null);
// create Java project
IJavaProject javaProject = JavaCore.create(project);
// Set the Java build path
IFolder binFolder = project.getFolder("bin");
binFolder.create(false, true, null);
javaProject.setOutputLocation(binFolder.getFullPath(), null);
// Link source folder
ArrayList<IClasspathEntry> entries = new ArrayList<IClasspathEntry>(
Arrays.asList(javaProject.getRawClasspath()));
// remove all other source entries, because the main project folder
// is a source entry and we can't save other source entry nested in
// it
for (int i = 0; i < entries.size(); i++) {
if (entries.get(i).getEntryKind() == IClasspathEntry.CPE_SOURCE) {
entries.remove(i);
}
}
IPath srcPath = javaProject.getPath().append(
srcFolderLocationInTheProject);
IClasspathEntry srcEntry = JavaCore.newSourceEntry(srcPath, null);
entries.add(srcEntry);
javaProject.setRawClasspath((IClasspathEntry[]) entries
.toArray(new IClasspathEntry[entries.size()]), null);
//link the folder with the resources
IFolder srcFolder = project.getFolder(srcFolderLocationInTheProject);
srcFolder.createLink(new Path(absolutePathToDocument.replaceFirst("file:/", "")), IFolder.FOLDER, null);
return "file:/"
+ ResourcesPlugin.getWorkspace().getRoot().getLocation()
+ "/" + projectName + "/" + srcFolderLocationInTheProject;
} catch (Exception e) {
e.printStackTrace();
try {
project.delete(true, null);
} catch (CoreException e1) {
e1.printStackTrace();
}
return null;
}
}
}

Hi Fadi J,
We love your Test snippet here at the Rascal project (http://www.rascal-mpl.org), but we are now wondering what the actual license of the snippet is. We plan to copy it, adapt it and re-organize it into our own library for analyzing C and C++ programs, but not without giving credit where it is due and not without checking if there are other copyright owners.
a) do you own the copyright of this code and are you willing to publish it as open-source?
b) are there any other copyright owners of this code that we should contact?
c) do you agree to publish this code under a BSD license?
Thanks!
