Hi,
I'm interested in this too. Currently I'm using Eclipse3.4.2 and
CDT5.0.2.
I have the facility to start a debug session in Eclipse from a command
line, by specifying the desired executable file (built outside of
Eclipse with a makefile) and a buildlog file. I then use the buildlog,
which consists of compilation lines containing -D (macros) and -I
(includes) directives and wire this into Project properties >
C/C++ Build > Discovery Options > "Load build output from file" (
Scanner Configuration Discovery Profile
org.eclipse.cdt.make.core.ScannerConfigurationDiscoveryProfile).
The starting point for this in my code is useBuildOutput()
below.
I get to the point where the "Load build output from file" text field
is populated and a Load is done, but the equivalent of the user
pressing Apply or OK is not done - this is the thing I'm still missing.
I'll shortly be migrating to use Galileo which I believe has improved
support for includes and macros using some kind of heuirstics ???
collection. I'm looking forward to the situation being eased with this,
but would still like to get my automatic build log thing working.
Once Eclipse has an accurate list of includes and macros any
conditional compilation sections in your code (lots in our users')
source editing really comes into its own with delightful features like
highlighting inactive code and folding etc which really improve
legibility.
Sorry for the hijack if this is not what you meant.

Purely for debugging I can observe the includes and macros that have
been set using this:
private void
logIncludePathsAndMacros(IProject project) {
ICProjectDescription projectDescription =
CoreModel.getDefault().getProjectDescription(project);
ICConfigurationDescription activeConfiguration =
projectDescription.getActiveConfiguration(); // or another config
ICFolderDescription folderDescription =
activeConfiguration.getRootFolderDescription(); // or use
getResourceDescription(IResource), or pick one from
getFolderDescriptions()
ICLanguageSetting[] languageSettings =
folderDescription.getLanguageSettings();
int id = 0;
for(int i=0; i<languageSettings.length; i++) {
String langId = languageSettings[i].getLanguageId();
if(langId.contains("org.eclipse.cdt.core.gcc")) {
id = i;
break;
}
}
ICLanguageSetting lang = languageSettings[id];
/*
* display includes
*/
ICLanguageSettingEntry[] includePathSettings =
lang.getSettingEntries(ICSettingEntry.INCLUDE_PATH);
writeToConsole("Project includes paths:");
for(int i=0; i<includePathSettings.length; i++) {
String ip = includePathSettings[i].toString();
writeToConsole(ip);
}
/*
* display macros
*/
ICLanguageSettingEntry[] macroSettings =
lang.getSettingEntries(ICSettingEntry.MACRO);
writeToConsole("\nProject macros:");
for(int i=0; i<macroSettings.length; i++) {
String ip = macroSettings[i].toString();
writeToConsole(ip);
}
}

Hi
all,
I am wondering how I can set the CDT's include paths either
programmatically or in a configuration file?
At the moment, the include lines of source files are reported as
warnings in the CDT editor, and I'd like to avoid forcing users to set
up paths manually when it can be automated or pre-set.
Regards,
George
