Take a look at the syslog file where LOG_LOCAL0 messages are redirected to see if you get hint about the exit cause -- that could be a simple "address already in use" if you have another process listening on tcp/8080. Otherwise you can place a breakpoint at app_run and "step" (or "next") to catch the exact position where the process exit's. Let us know, t.

Thank you! But my ultimate goal is to run klone on a target running qnx. I modified the Makefile you gave me to add "MAKL_PLATFORM = qnx-ppcbe" and got lots of compilation errors. Version 2.0.1pre4 works OK with qnx(but having debugging problems). I also tried the other debugging method (using syslog and dbg()) with Version 2.0.1pre4 and qnx. All I got in my syslog is the following(no debugging info): Jul 14 17:54:48 nto : [wrn][6328357:broker.c:105:broker_create] CGI support disabled, use --enable_cgi to enable it Jul 14 17:54:48 nto : [wrn][6328357:broker.c:112:broker_create] File system support disabled, use --enable_fs to enable it Is there a version that both supports qnx and has no debugging problems?

I've no GPIB experience, so I'm not the most qualified person to give a sensible advice, anyway, it sounds like a good idea :) Has GPIB any standard hi-level API ?

Thank you! But my ultimate goal is to run klone on a target running qnx. I modified the Makefile you gave me to add "MAKL_PLATFORM = qnx-ppcbe" and got lots of compilation errors. Version 2.0.1pre4 works OK with qnx(but having debugging problems). I also tried the other debugging method (using syslog and dbg()) with Version 2.0.1pre4 and qnx. All I got in my syslog is the following(no debugging info): Jul 14 17:54:48 nto : [wrn][6328357:broker.c:105:broker_create] CGI support disabled, use --enable_cgi to enable it Jul 14 17:54:48 nto : [wrn][6328357:broker.c:112:broker_create] File system support disabled, use --enable_fs to enable it Is there a version that both supports qnx and has no debugging problems?

Sorry Ying, in these very days we are completely restructuring our test environment, so I have no way to test the QNX build environment.

I've no GPIB experience, so I'm not the most qualified person to give a sensible advice, anyway, it sounds like a good idea :) Has GPIB any standard hi-level API ? In such case you could start from a simple RPC-style HTTP mapping. ciao, t.
