[Ikvm-developers] Problem with mono default profiler
|
From: Michael B. <mb...@gm...> - 2009-03-17 15:59:16

Hi All,
I am trying to profile a mixed Java/C# application running on Linux (Fedora
Core 10) using the Mono default profiler.
(I have not had any luck using the Mono Logging profiler or Valgrind.)
Please see my system information and stack trace below.
My run script looks like the following:
#!/bin/sh
export MONO_IOMAP=all
export MONO_REGISTRY_PATH=/home/mbaker/.mono/registry
mono --trace=M:Microsoft.Win32.KeyHandler:Drop --debug --verbose
--profile=default:stat,alloc,file=prof.out hrc.exe
I don't think either Mono environment variable has an affect on my run.
I think my program is dying on the first line of this method (quoted below),
but I don't know the cause.
Since my program does not exit cleanly, I do not get the profiler output.
Any help or insight is greatly appreciated.
Mike
