Re: Debugging a Vlc dll with GDB.

[personel personel <lepascal01@yahoo.com>]

Hello Daniel,


I tried:

    gdb -silent -e VLCTest.exe -s VLCTest.exe == "no
                     debugging symbols found"

   (gdb) break libvlc_new
    No symbol table is loaded. use the file command 


As you can see, gdb does not ask me if I want to set a
pending breakpoint. Why? It cant read any symbol table
so how can it knows that the function is not into
VLCTest.exe but in a DLL?

If you have another suggestion, I would be pleased.

Thank you,

abraxis
