Specifically, on ELF and SunOS systems, ld will search a directory for a library called libnamespec.so before searching for one called libnamespec.a. (By convention, a ".so" extension indicates a shared library.) Each warning consists of a pair of lines: the first describes the symbol just encountered, and the second describes the previous symbol encountered with the same name. Even when ld is configured to support alternative object formats, you don't usually need to specify this, as ld should be configured to produce as a default output format the most In addition to the options common to all targets, the i386 PE linker support additional command line options that are specific to the i386 PE target. this content
The GNU linker ld is meant to cover a broad range of situations, and to be as compatible as possible with other linkers. This option is only meaningful on ELF platforms which support shared libraries. -Bsymbolic-functions When creating a shared library, bind references to global function symbols to the definition within the shared library, Information forwarded to [email protected], Stefan Völkel
Non-option arguments are object files or archives which are to be linked together. This happens when an "ld -shared" link includes a shared library as one of the input files. The address will only be changed if it not explicitly specified; that is, if the "SECTIONS" command does not specify a start address for the section. --warn-shared-textrel Warn if the linker filename is simply a flat file, with one symbol name per line.
This is typically used when creating shared libraries to specify additional information about the version hierarchy for the library being created.

Normally the linker will add a DT_NEEDED tag for each dynamic library mentioned on the command line, regardless of whether the library is actually needed or not. --as-needed causes a DT_NEEDED more like that. Can cats leave scratch marks on cars? thx!
You may use this option multiple times on the command line: it affects library searching for -l options which follow it. -Bgroup Set the "DF_1_GROUP" flag in the "DT_FLAGS_1" entry in share|improve this answer answered Apr 21 '14 at 16:35 Netch 1,9541510 add a comment| up vote 2 down vote Use gcc -rdynamic or -Wl,--export-dynamic (the -Wl tells to send the next If it wishes to call the system function, it should call "__real_ symbol ".

Note - symbols whose values are computed by an expression which involves a reference to a previous value of the same symbol may not have correct result displayed in the link https://github.com/rvm/rvm/issues/2757 If the dynamic linker resolves any symbols from the filter object, it will first check whether there is a definition in the shared object name. Rdynamic Note - this option does not enable linking against shared libraries. For example, --trace-symbol foo and --trace-symbol=foo are equivalent.

Since the offset in base-register relative mode is fixed and relatively small (e.g., 16 bits), this limits the maximum size of the constant pool. Unique abbreviations of the names of multiple-letter options are accepted.
We document -rdynamic as the way to pass down -export-dynamic, so if the -e handling is on-purpose ... Unfortunately, some C libraries use this practise, so you may get some warnings about symbols in the libraries as well as in your programs. This option allows you to find potential problems from combining global symbols. As a GNU extension, it is possible to allow their use in executable images as well, or to (probably pointlessly!) disallow it in object files, by using these two options.
What is the first movie to show this hard work message at the very end? The file may itself contain additional @file options; any such options will be processed recursively. -a keyword This option is supported for HP/UX compatibility. On such a system, to link a file "hello.o": ld -o

This switch requests ld to use the traditional format instead. The default behaviour can be restored with --copy-dt-needed-entries. [email protected] - #install gem rake...

Aside from its flexibility, the GNU linker is more helpful than other linkers in providing diagnostic information.
Note that those options are only available for ELF systems. --hash-size=number Set the default size of the linker's hash tables to a prime number close to number. ld accepts Linker Command Language files written in a superset of AT&T 's Link Editor Command Language syntax, to provide explicit and total control over the linking process. Copying from repo to src path... Display the linker script being used by the linker. --version-script=version-scriptfile Specify the name of a version script to the linker.
This option should be used with caution as it overrides the search path that may have been hard compiled into a shared library.
