Title: Symbol file
Post by: antonien on February 05, 2011, 04:27:53 pm

Looking at the search section, I am not the only guy who get stuck with that warning :

Code

ERROR: Symbol file could not be found.  Defaulted to export symbols for ntdll.dll -

I couldn't find a definite answer in the search : is it possible to cope with it ? Where can I find that symbol file ?

Thanks in advance for the answer.
I'll google for it in the mean time and if I find the answer, I'll post it.

Best regards

Which compiler? If it is gcc you can't, because it doesn't support MS style debug info.

Thanks for the reply.
It is cdb.

Read the cdb manual...
There should be a command that tells the debugger to load the symbols from MS's symbol servers.
Another option is to download it yourself and place it, where the debugger can find it.

p.s. can you paste the debugger's debug log ( Settings -> Compiler & Debugger -> Debugger -> Display debug log).
p.p.s. please use code tags

Thanks for the answer. Debug log is :

Obviously, symbol path is set to my program directory.
Do I have to write something in the Dubugger initialization commands ? Where to put the symbol path ?
I did put a "_NT_SYMBOL_PATH" with my "c:\CB nightly build\Symbols" symbol path as an environment variable but it doesn't work.
Id doesn't work either with the "srv*c:\symbols*http://msdl.microsoft.com/download/symbols" setting for "_NT_SYMBOL_PATH".

Thanks in advance.

I removed any "space" character from my symbol path and put it in c:\Symbols. To be sure, I declared it as a _NT_SYMBOL_PATH environment variable.
I declared it in the "Projetc>Properties>Debugger>Additional debugger search dirs" and now it is recognized as symbol search path by the debugger... but it fails again and again !
