IDEA-19242 Debugger fails starting on linux

Issue is visible to: All Users

When trying to use the flex debugger on linux, several problems arise:

1. "fdb" script not executable

When clicking "Debug" on a flex configuration, IDEA does nothing at all. A look into the logfile showed me this:

I listed the file, and found it had 644 as rights, missing the x-bit, hence not being executable. Okay, I made it executable, which took me a step further.

Shouldn't IDEA either (a) show the error message instead of being silent, or (b) execute "fdb" script as a shell, like this "/bin/sh -c fdb", which circumvents the need for x-bit on a linux box?

2. Next, clicking Debug, shows a dialog telling me:

Flex Debugger Error
"Unexpected debugged player communication problem".

And the log shows nothing...

Environment: Linux, ubuntu 7.10.
JDK: 1.6.0_06

Issue was resolved

Are you using FireFix 3 as browser?

Firefox2 on ubuntu.
Why is the browser important here?

For second problem you are reporting ("Unexpected debugged player communication problem"),
fdb launches browser for the debugger, if 'fdb' replies with 'session disconnected' just after startup then such error is reported. The problem started to appear under FireFox 3

Ahh, okay.
But I am running firefox2.
Please tell me if I can provide more debugging info.

Sure, but I am not quite sure what you mean by "launching fdb with your swf / wrapper / url" ??

Please, execute from command line '/usr/local/flex/current_sdk3/bin/fdb <your url to wrapper / swf>' similar as you do in IDEA debug

Oups, output was "File not found: flashplayer" :-)
I then took path to standalone player and put into PATH variable, and then output is:

The problem has shifted now, with latest build (#8810). Now, the run dialog tells me "No valid flex SDK is specified for module", even though it is.
I tried recreating the flex sdk and assign again to each module, but the problem persists.
I will attach screenshot shortly.
