Gdb manually load shared library

step 3: In your build directory, decompress www.doorway.ru and extract the source files from the archive. Once the files have finished extracting, change your working directory to the gdb directory that was automatically created in your build directory. $ build gzip -d www.doorway.ru $ build tar xfv gdbtar $ build cd gdb Library Name Specifies the library to load debugging symbols for. Regular Expression When specified, GDB will load the symbols for all currently loaded libraries matching the specified expression. Remarks. Normally, GDB will load the shared library symbols automatically. You can control this behavior using set auto-solib-add command. However, in some cases (e.g. .  · $ gdb executable_name core_file_name (gdb) The above command will load the core file for the executable and prompts a gdb shell. You can use gdb backtrace or other commands to examine what really happened. Note that the core_file will be ignored, if the executable is running under gdb.

Remarks. The info sharedlibrary command is only valid when the debugged application has already started.. If the info sharedlibrary command reveals that some of the symbols for the currently loaded libraries are not loaded, you can load them manually using the sharedlibrary command.. Examples. This example shows a sample output of the info sharedlibrary command. This should show all the gdb messages we send and receive and I'd be interested in seeing if we can determine why that shared library is not being loaded. The additionalSOLibSearchPath is calling set solib-search-path underneath to set the path, which according to the gdb documentation should give it a location on where to load the shared library. Stopped due to shared library event (no libraries added or removed) Loaded '/lib64/ld-linux-xso.2'. Symbols loaded. [Inferior 1 (process ) exited with code ].

The symbols should be loaded on the memory address where the shared library is loaded. Following is an example of loading the symbols: start gdb ~$ gdb www.doorway.ru GNU gdb (Ubuntu ubuntu1~) Copyright (C) Free Software Foundation, Inc. (gdb) info sharedlibrary No shared libraries loaded at this time. Create break point (on main or any other place) and start the debug.
