I have 2 custom toolchains, which I use in the old CDT (1.2.1) and Eclipse version 2. Now I am trying out the new versions of Eclipse (3.0RC1) and CDT (2.0RC2), but my toolchains don't work anymore. First I just tried to copy them to the plugin directory, which didn't work and after that I recreated them in the new Eclipse/CDT using the procedures as described in the document : "Managed Build System Extensibility", I did not enter everything again, instead I just copied the contents of the old XML file to the new one, but this gave the same problem. The problem is that building does not work and also I can not change any settings I have defined in my toolchain file. If my toolchain file is required, just drop me an e-mail. The log file says the following : ================================================================================ !SESSION Jul 01, 2004 10:28:25.250 --------------------------------------------- eclipse.buildId=unknown java.version=1.4.2_04 java.vendor=Sun Microsystems Inc.

The target definition has to be updated to include the following line: makefileGenerator="org.eclipse.cdt.managedbuilder.makegen.gnu.GnuMakefileGenera tor" This was a test case I missed. When the build system tries to implement a makefile generator that implements IManagedBuilderMakefileGenerator, it will return NULL if one is not defined. It would be better if the Gnu generator was returned as the default. Will add this check for the next release. Should update the release notes with this.
PR was not targeted to any particular release. Changing target milestone to 2.1
Changing target milestone. Will be fixed in next release.
Fixed in the head and 2.0.1 by returning the Gnu makefile generator if nothing is specified for the target
Han, if this works for you now, could you mark the defect verified? Or send me your toolchain and I'll try it.
Verified fixed. I've tried building your target definition, Han, that doesn't have the line: makefileGenerator="org.eclipse.cdt.managedbuilder.makegen.gnu.GnuMakefileGenera tor" and there isn't any more NPE in the log. Can you mark this defect verified as I don't have the button, not being the reporter. Thanks
