This is a BETA release of a completely rewritten GNU linker.
|
|
It is distributed with other "binary utilities" which should
|
|
be in ../binutils. See ../binutils/README for more general notes,
|
|
including where to send bug reports.
|
|
|
|
There are many new features of the linker:
|
|
|
|
* The linker uses a Binary File Descriptor library (../bfd)
|
|
that it uses to read and write object files. This helps
|
|
insulate the linker itself from the format of object files.
|
|
|
|
* The linker support a number of different object file
|
|
formats. It can even handle multiple formats at once:
|
|
Read two input formats and write a third.
|
|
|
|
* The linker can be configured for cross-linking.
|
|
|
|
* The linker contains a control language.
|
|
|
|
* There is a user manual (ld.texinfo), as well as the
|
|
beginnings of an internals manual (ldint.texinfo).
|

|
Installation
|
|
============
|
|
|
|
See ../binutils/README.
|
|
|
|
If you want to make a cross-linker, you may want to specify
|
|
a different search path of -lfoo libraries than the default.
|
|
You can do this by setting the LIB_PATH variable in ./Makefile.
|
|
|
|
To build just the linker, make the target all-ld.
|
|
|
|
Porting to a new target
|
|
=======================

Known problems
|
|
==============
|
|
|
|
HP/UX 9.01 has a shell bug that causes the linker scripts to be
|
|
generated incorrectly. The symptom of this appears to be "fatal error
|
|
- scanner input buffer overflow" error messages. There are various
|
|
workarounds to this:
|
|
* Build and install bash, and build with "make SHELL=bash".
|
|
* Update to a version of HP/UX with a working shell (e.g., 9.05).
|
|
* Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in
|
|
genscripts.sh with "sh ${srcdir}..." (no parens) and make sure the
|
|
emulparams script used exports any shell variables it sets.
