| Re: [cdt-dev] External build tool: Cannot run program "bjam": Unknown reason |

I guess that at some point there will be an exec which tries to invoke an external process called "bjam". If that fails, you should be able to get some information
about what "Unknown reason" means. (But I'm just shooting in the dark here.) /Jesper From: cdt-dev-bounces@xxxxxxxxxxx [mailto:cdt-dev-bounces@xxxxxxxxxxx]
On Behalf Of Steve Lorimer I have no idea what I'm looking for though. Any suggestions? On 31 March 2016 at 03:17, Jesper Eskilson <Jesper.Eskilson@xxxxxxx> wrote: You can tell strace to filter out uninteresting events. For example "-e trace=process" will only
include system calls which involve process management. You can also filter on specific system calls, e.g. "-e trace=chmod". Without filtering, strace output quickly becomes unusable. /Jesper From:

Hmm - my strace output is up to 2 GB now without the issue cropping up... not sure this is feasible. On 30 March 2016 at 14:30, Jesper Eskilson <Jesper.Eskilson@xxxxxxx> wrote: The strace-output does not seem to cover e.g. the spawner process. Did you use the "-f" option to
strace to have it follow child processes? Eclipse will spawn a helper process called "spawner" which does the actual system call to start the subprocess, and there is no mention of this in your strace output. /Jesper From:

$ strace eclipse 2> /tmp/eclipse.strace.out It seems to stop during launching and then the following message is the last returned wait4(15567, log4j:WARN No appenders could be found for logger (org.eclipse.jgit.util.FS). log4j:WARN Please initialize the log4j system properly. Please see log attached Any insight greatly appreciated! Thanks Steve
