Build Identifier: cdt-master-7.0.0-I201003151310.zip When I try to run a helloc project, I see that a error(?) message box gets displayed for a split second then nothing happens. .metadata/.log has the following. !ENTRY org.eclipse.debug.core 4 125 2010-04-30 12:12:07.919 !MESSAGE Error logged from Debug Core: !STACK 0 java.io.IOException: read error at org.eclipse.cdt.utils.spawner.SpawnerInputStream.read0(Native Method) at org.eclipse.cdt.utils.spawner.SpawnerInputStream.read(SpawnerInputStream.java:66) at java.io.BufferedInputStream.read1(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at java.io.FilterInputStream.read(Unknown Source) at org.eclipse.debug.internal.core.OutputStreamMonitor.read(OutputStreamMonitor.java:144) at org.eclipse.debug.internal.core.OutputStreamMonitor.access$1(OutputStreamMonitor.java:134) at org.eclipse.debug.internal.core.OutputStreamMonitor$1.run(OutputStreamMonitor.java:207) at java.lang.Thread.run(Unknown Source) Reproducible: Always Steps to Reproduce: 1. untar eclipse-SDK-3.6M6-linux-gtk.tar.tar 2. install cdt-master-7.0.0-I201003151310.zip via Install New Software.. and select only the first (basic) CDT features. 3. Restart eclipse ./eclipse -clean -data runtime -showlocation -vm [path]/jre1.6.0_17/bin/java -vmargs -Xmx758M 4. Create Hello World ANSI C Project. Build. 5. Run->Run As->Local C/C++ APplication 6. I get the error above.
OK. Looks like everything works if I first selects "Debug As" and set up the debugger before selecting "Run As". Fortunately I figured this out but I'd say this's user-unfriendly.

Fortunately I figured this out but I'd say > this's user-unfriendly. That is not very good. I wonder if this is the same as bug 308905. Do you have EDC installed too? Can you try with one of the latest nightly builds, or wait until Monday for the M7 build.
> Can you try with one of the latest nightly builds, or wait until Monday for the > M7 build. OK. I'll try again with M7 on Monday.
With M7, I get an error box "Problem Occurred" 'Launching 1' has encountered a problem. Plug-in "org.eclipse.cdt.launch" was unable to instantiate class "org.eclipse.cdt.launch.internal.LocalCDILaunchDelegate". Again, if I select the Debug As first, everything works fine. Is EDC included in "CDT Main Features" or "CDT Optional Features"? I only have everything from CDT Main Features installed.

I only have > everything from CDT Main Features installed. I tried your steps exactly and I can't reproduce this. I'm on a Linux 32bit. I installed eclipse M7 then CDT M7 then build a new Hello World C project and then Run-> Run As works fine for me.
Mmm.. >I'm on a Linux 32bit. Me too. I'm on EL5. >I installed eclipse M7 then CDT M7 I tried with eclipse M7 too. I tried installing only CDT Main Features" first then also "CDT Optional Features" (but not Remote Launcher) with it and still got the same error. I'm using JRE1.6.

I can't reproduce but I have a theory. Which perspective are you in when you to the Run As? Do you get an automatic perspective switch during the launch?
Thanks for looking. (Sorry I didn't see this till now). I can not reproduce this any longer myself. Re: perspective I don't remember clearly but I started out in Java perspective and was in C/C++ perspective when I did "Run As". The perspective switch is not automatic for me. I get a prompt when I create a C/C++ project. Right now I tried both cases (Yes and No to the prompt) and still could not reproduce the problem.
Not sure why this is assigned to me.
