Build Identifier: Version: Helios Service Release 1, Build id: 20100917-0705 After downloading both the CDT and JDT, each were unpacked unquely (for example, folders eclipse-cpp and eclipse-java). I tested each by launching eclipse.exe with in each folder. No tweaks were made to either installation - this is stock out-of the-box. Launching the C++ IDE results in the Java IDE running. To ensure I did not cross wires, I performed the download/unpack/launch a second time. The IDE is clearly JAVA. See attached. Java and C++ development co-installations or side-by-side installations seem like a common case. In my particular case (I realize the world does not revolve around me), I need an Android C/C++ shared object (crypto and image processing) coupled with a Android Java program (GUI). Finally, I'm new to Eclispe, so if I have missed something, please accept my apologies. I did try to RTFM at http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/heliossr1 and http://www.eclipse.org/downloads/packages/eclipse-ide-cc-developers/heliossr1. Reproducible: Always Steps to Reproduce: 1. Download and unpack JDT. Unpack to a unique name. 2. Download and unpack CDT. Unpack to a unique name. 3. Run eclipse.exe from JDT unpack location. Take all default settings. 3. Run eclipse.exe from CDT unpack location. Take all default settings.

It looks like you are using the same workspace with both installations. When you open the same workspace with C/C++, it tries to open in the last perspective which is Java, but you don't have the Java plugins in this installation (notice the < > in <Java> perspective). Unless you really want to separate the two installations, I suggest that you use the Java package and install CDT from the Helios update site, in Help > Install new software, work with: Helios. Under Programming Languages, check C/C++ Dev tools. You could also do it the other way around, install the CDT package, then install JDT from Help, etc.

Moving to a single .../eclipse/ and adding software was the trick. I wondered how Fedora did it so gracefully. Trying to locate information on a topic with no known keywords is frustrating ("no known" due to my ignorance of the environment). By the way, unpacking a C++ download and a Java download into the same directory has ill effects. I tried it because I did not know what I was looking for. Jeff
