Re^5: LD_LIBRARY_PATH setting

This is higly weird because I would expect that code to go into an endless self-exec loop instead of producing that error message. You never check for the self-restart flag.

Maybe consider adding more debug output, for example two print statements around the exec statement:

...
    print "Rerunning $0 --restarted @ARGV\n";
    exec $0, '--restarted', @ARGV
        or print STDERR "couldn't exec foo: $!";
...

Also, if you put your code in between <code>...</code> tags, it renders and downloads much better.

In the code I originally posted, I included a guard flag that told the program whether it had been restarted. The code that you have not shown does not seem to guard against an endless restart loop, as evidenced by the small and incomplete part of its output that you've shown. Maybe now is a good time to revisit the approach I had outlined in my first program? `if( ! $ENV{PDUPRE_RESTART}) { $ENV{PDUPRE_RESTART} = 1; print "Restarting as '$0, @ARGV'\n"; ... exec $0, @ARGV or print "Exec error when restarting $0 @ARGV: $!"; exit 1; };` [download] Alternatively, if you want to keep the `--restarted` command, maybe you can check `@ARGV` whether it contains `--restarted`? `if( ! grep { /^--restarted$/ @ARGV) { print "Restarting as '$0 --restarted @ARGV'\n"; exec $0, '--restarted', @ARGV or print "Exec error when restarting $0 @ARGV: $!"; exit 1; };` [download] Again, you can help us help you diagnosing things better by posting a twenty-line self-contained example that reproduces the behaviour you're seeing.

OK, Thank you. Now, it works Patrick Dupre Universite du Littoral, FR Dunkirk	[reply]
