problem about .sym file

[enigma19971]

carbide console give following message:
copy "\Symbian\9.2\S60_3rd_FP1_2\EPOC32\BUILD\MobileVideoPlayer\group\IMVP\GCCE\UDEB\hello.exe" "\Symbian\9.2\S60_3rd_FP1_2\EPOC32\RELEASE\GCCE\UDEB\hello.sym"

i am wondering what the .sym file is? why the carbide copy the exe file to be a .sym file,other than a .exe?
in consequence, .pkg file can't locate the .exe. and makesis
failed.

but ,when i use command line: abld build gcce udeb, it's all ok.

i have no ideal how to deal with it.

If i am not wrong the .sym files is used by carbide.C++ for debugging code parsing etc.
