dedicated server error

I tried to open a dedicated server and i got this error:
error: Failed to open/read local data from file/application
Add “-debug” to the ./srcds_run command line to generate a debug.log to help with solving this problem

CRASH: Wed Jan 5 19:53:05 IST 2011
Start Line: ./srcds_linux -console -game garrysmod +maxplayers 12 +map gm_construct -autoupdate -debug
End of Source crash report
