ktrace/kdump are not available any more on Mac OS X (since 10.5).
I found "dtruss" - but got into a catch-22:
1. Running 'rm' as-is gives error:
$ $D/rm -r $D/a $D/b
/Users/admin/Projects/coreutils-8.20.90-e27bfd/src/rm: unable to record
current working directory: Too many open files
2. Running with 'dtruss' requires root:
$ dtruss $D/rm -r $D/a $D/b
dtrace: failed to initialize dtrace: DTrace requires additional privileges
3. Running with 'sudo', 'rm' doesn't fail:
$ sudo dtruss $D/rm -r $D/a $D/b 2>/tmp/rm_trace.txt
[ $D/a and $D/b are deleted ]
Attached is the "rm_trace.txt" file, but it won't show failure...
I'm not familiar with MacOS, so any suggestions are welcomed.
Pádraig:
running "make check" in gnulib-test directory failed 8 tests (attached).
I can try instrumentations and other tests, but please tell me how to run them.
