The keyword argument must be one of the strings archive, shared, or default. -aarchive is functionally equivalent to -Bstatic, and the other two keywords are functionally equivalent to -Bdynamic. The --reduce-memory-overheads switch may be also be used to enable other tradeoffs in future versions of the linker. --build-id --build-id=style Request creation of ".note.gnu.build-id" ELF note section.

The contents of the note are unique bits identifying this linked file. The difference between -rpath and -rpath-link is that directories specified by -rpath options are included in the executable and used at runtime, whereas the -rpath-link option is only effective at link Compute the kangaroo sequence How to deal with sewage on a map with no water anywhere more hot questions question feed default about us tour help blog chat data legal privacy This is only meaningful when generating dynamically linked ELF executables. why not find out more
Already have an account? Use -Bdynamic for this. -o output --output=output Use output as the name for the program produced by ld; if this option is not specified, the name a.out is used by default. If it wishes to call the system function, it should call "__real_ symbol ".
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut. How does NumPy solve least squares for underdetermined systems? See --entry and --undefined. The assumption is that the user knows what they are doing and deliberately wants to link in these unknown input files.
In such a case it is possible to use unintentionally a different search path than the runtime linker would do. Xlinker Why do train companies require two hours to deliver your ticket to the machine? AUDITLIB is not checked for existence, nor will it use the DT_SONAME specified in the library. navigate here Merging a common symbol with a previous larger common symbol.
The BeOS kernel for example patches shared libraries at load time to select whichever function is most appropriate for the current architecture. If this option is not specified, an absolute file is produced. Note that this will fail to work with object file formats which do not support arbitrary sections. For instance, a frequent use of ld is to link standard Unix object files on a standard, supported Unix system.

In Harry Potter book 7, why didn't the Order flee Britain after Harry turned seventeen?
On some platforms, the --relax option performs global optimizations that become possible when the linker resolves addressing in the program, such as relaxing address modes and synthesizing new instructions in the Why is absolute zero unattainable? Index User list Rules Search Register Login Welcome to the forums. It seems to be passed > as -e xport-dynamic to the linker now, resulting in an undefined symbol > for me with a trivial hello-world. -export-dynamic was passed down by an
date: invalid date '2016-10-16' reading through the definition of `\cfrac` in AMSMath How can I make LaTeX break the word at the end of line more beautiful? All rights reserved. If you do this, you should not put the definition of "__real_malloc" in the same file as "__wrap_malloc"; if you do, the assembler may resolve the call before the linker has Why must the speed of light be the universal speed limit for all the fundamental forces of nature?
A link map provides information about the link, including the following: • Where object files are mapped into memory. • How common symbols are allocated. • All archive members included in If you need more elaborate expressions, consider using the linker command language from a script. Debian distribution maintenance software pp.
Note: Although a writable text section is allowed for PE-COFF targets, it does not conform to the format specification published by Microsoft. --no-omagic This option negates most of the effects of If you use "dlopen" to load a dynamic object which needs to refer back to the symbols defined by the program, rather than some other dynamic object, then you will probably Normally, the linker will not produce an output file if it encounters errors during the link process; it exits without writing an output file when it issues any error whatsoever. -nostdlib For options whose names are multiple letters, either one dash or two can precede the option name; for example, -trace-symbol and --trace-symbol are equivalent.
These include :- Python 2.7 with development kit and several modules used by code_aster (numpy, qt4, etc)- a recent GCC (>=4.8) with Fortran support- QT4- binutils, coreutils (those provided by MacOS Specifies a list of archive libraries from which symbols should not be automatically exported. Future releases of ld may support similar functionality for other architecture families. -b input-format --format=input-format ld may be configured to support more than one kind of object file. See the -( option for a way to force the linker to search archives multiple times.
If no binary input files at all are specified, the linker does not produce any output, and issues the message No input files. This is the same as the previous case, except that the symbols are encountered in a different order.
This feature permits the linker to link against a file which appears to be an object or an archive, but actually merely defines some symbol values, or uses "INPUT" or "GROUP" If a symbol in that archive is needed to resolve an undefined symbol referred to by an object in an archive that appears later on the command line, the linker would As a result, you have many choices to control its behavior. This option may be used more than once.
The default behaviour can be restored by using the command line switch --check-sections.

Note---if the linker is being invoked indirectly, via a compiler driver (e.g.
initfirst This option is only meaningful when building a shared object. So you can fix this with your own means (e.g. Options that take values may be separated from their values by either a space or an equals sign. --add-stdcall-alias If given, symbols with a stdcall suffix (@nn) will be exported as-is
