gdb error while reading shared library symbols Waverley, Massachusetts

There's nothing in the bug report that gives me a clue what is wrong. -- Daniel Jacobowitz Thread at a glance: Previous Message by Date: c++/1701: Error while reading shared library The info files command, described below, lists all the sections and their addresses. On systems with memory-mapped files, an auxiliary file named `filename.syms' may hold symbol table information for filename.

Note You need to log in before you can comment on or make changes to this bug. GDB circumvents the problem by considering the symbol to have the name foo, which may cause other problems if many symbols end up with this name.

It is also the program executed when you use the run command. On HP-UX systems, GDB detects the loading of a shared library and automatically reads in symbols from the newly loaded library, up to a threshold that is initially set but that My guess is your Makefile or asm.s are breaking shared library loading. –poolie Feb 20 '12 at 6:00 add a comment| active oldest votes Browse other questions tagged 11.10 gdb or Error while mapping shared library sections: /lib/ No such file or directory.

The purpose of this two-stage reading strategy is to make GDB start up faster. Omitting filename means to discard information on the executable file.

WDYT? -- Pedro Alves 2010-04-12 Daniel Jacobowitz Pedro Alves Group errors for many missing shared libraries, ported from the symbian-fsf branch. As with files loaded automatically, it only loads shared libraries required by your program for a core file or after typing run. This option is useful when debugging with gdbserver. If so, GDB maps in the symbol table from `filename.syms', starting up more quickly.

Otherwise, symbols must be loaded manually, using the sharedlibrary command. Error while mapping shared library sections: /lib/ No such file or directory. Beyond that threshold, symbols from shared libraries must be explicitly loaded. Implementation of a generic List Putting pin(s) back into chain Unproven vs.

Animal Shelter in Java Is there a Korean word for 'Syllable Block'? Thanks. This error indicates that it does not do so. This can be used if the exec file does not contain section addresses, (such as in the a.out format), or when the addresses specified in the file itself are wrong.

GDB circumvents the problem by treating the inner block as if it had the same scope as the outer block. If you encounter such a problem and feel like debugging it, you can debug gdb with itself, breakpoint on complain, then go up to the function read_dbx_symtab and examine *bufp to Format For Printing -XML -Clone This Bug -Top of page First Last Prev Next This bug is not in your last search results.

Do not add to the section table here. Type "show warranty" for details. I have read many other posts on here (and various other places on the internet) about this, however, I cannot seem to find a solution. See the descriptions of the file options `-mapped' and `-readnow' (available on the command line, and with the commands file, symbol-file, or add-symbol-file, described below), for more information.

GDB automatically loads symbol definitions from shared libraries when you use the run command, or when you examine a core file.
