-
-This package contains my ELF dynamic linkers (ld-linux.so.1), dynamic
-linker library (libdl.so.1) and utilities (ldconfig and ldd) for Linux.
-
-You need Linux kernel 2.0.0 or later with ELF support compiled in
-(i.e. not loaded as a module) to use this package.
-
-The dynamic linker is used to bootstrap programs and load shared
-libraries at startup. The dynamic linker library is used to
-dynamically load shared libraries after a program is running.
-Ldconfig is used to automatically update the symbolic links to shared
-libraries and build the cache file used by the dynamic linker. Ldd is
-used to list the shared libraries used by a program.
-
-Please see the included manual pages for further details.
-
-To install, simply run "sh instldso.sh" as root. Ready-to-go versions
-of all end-products are provided so nothing should need to be compiled
-or linked. If you are still using libc5 as your primary development
-library, you should use the "--devfiles" option when running
-instldso.sh to install the file needed to compile with libdl.
-
-ELF versions of gcc, binutils and libc are now required to compile
-everything, including the old, unsupported, a.out dynamic linker.
-Finally, an optimization level of O2 or higher must be used to compile
-ld-linux.so and libdl.so due the use of inline functions.
-
-Notable contributors to this package include Eric Youngdale, Peter
-MacDonald, Hongjiu Lu, Linus Torvalds, Lars Wirzenius, Mitch D'Souza,
-Rik Faith, Andreas Schwab and Adam Richter (not necessarily in that
-order).
-
-###################### IMPORTANT NOTICES #############################
-
-A.OUT SUPPORT:
-
-As of ld.so-1.9.0, the old, a.out dynamic loader is no longer
-officially supported. The code is still included and built, but I
-make no promises that it will work. I will accept patches for it,
-but they will not be tested by me.
-
-GLIBC (AKA LIBC6) SUPPORT:
-
-As of ld.so-1.9.0, the main focus of this package is to ease the
-transition to libc6. No significant, new features are expected to be
-added. If you need new features, switch to libc6.
-
-Except for libpthread.so, the sonames of the core libraries provided
-with libc6 have been chosen so they do not conflict with those
-provided by libc5 and ld.so. However, the current plan is not use
-new, nonconflicting sonames for other libraries such as ncurses and
-X11. This presents two problems. First, libraries using the same
-soname for both libc5 and libc6 can not be placed in the same
-directory. Second, the dynamic linkers need to make sure not to load
-a library for the wrong version of libc.
-
-The first problem is easy. Just move the old, libc5-based libraries
-to new directories (e.g. /lib/libc5-compat, /usr/lib/libc5-compat,
-etc.) and add those directories to /etc/ld.so.conf. Then install the
-new, libc6-based versions in the standard places.
-
-The second problem is more difficult. Ideally, the dynamic linkers
-would be changed to perform a complete dependency analysis on every
-library to be loaded to make sure the wrong versions aren't used.
-This approach doesn't seem worth the added complexity, especially
-since we now have symbol versioning for ELF libraries. Instead a
-simpler approach will be used, at least initially.
-
-Ldconfig has been modified to perform a (currently simple) dependency
-analysis on libraries and to store an indication in /etc/ld.so.cache
-of whether a library is for libc5, libc6 or an unknown libc. The
-dynamic linkers then only need to make a simple check at run-time to
-make sure they don't load the wrong version of a library.
-
-The dynamic linker for libc5 provided in this package, has already
-been modified to use the new information in /etc/ld.so.cache. For
-glibc versions 2.0.1 and earlier, the dynamic linker for libc6 needs
-the patch contained in glibc.patch. You should apply the patch and
-rebuild glibc before using the new ldconfig.
-
-As stated above, the dependency analysis currently done by ldconfig is
-rather simple. Basically, it looks for the sonames used by the
-various versions of libc, libm and libdl. For any approach using a
-dependency analysis such as this to work, it is very important that
-shared libraries be built with complete dependency information. This
-can be done by using the appropriate -l options when running 'gcc
--shared'. For example, when building libfoo.so which depends on libc
-and libbar, you should add -lbar and -lc gcc command line.

- exited abnormally.
-
-Changes in version 1.7.11:

- the handle returned from dlopen(0, *).
-
-Changes in version 1.7.10:

- LD_{ELF_}PRELOAD.
-
- Changed ld.so and ld-linux.so to truncate all variations
- of LD_PRELOAD and LD_LIBRARY_PATH for set[ug]id programs.
-
-Changes in version 1.7.5:
-
- Changed ldconfig to recognize libraries without any
- version number (eg. libXYZ.so).
-
- Changed ldconfig to not generate a corrupt cache when
- the disk is full or other write errors occur.
-
- Changed ld-linux.so to map files with MAP_DENYWRITE to
- keep them from being changed while the file is in use
- (Rick Sladkey).
-
- Changed libdl to not overwrite the scope pointer of a
- library if it was already loaded (H.J. Lu).
-
- Changed ld-linux.so so gdb can be used on constructors
- (Eric Youngdale).

- name at the time it is loaded instead of trying to figure
- it out after the fact.
-
-Changes in version 1.7.0:

- for ELF libraries and make it available to ld-linux.so.
- The soname for DLL libraries is still determined by
- truncating the minor numbers from the image file name.
-
- Changed ldconfig to no longer support the undocumented
- sort options.
-
- Changed ld.so to require a valid cache to find libraries
- in directories specified in ld.so.conf. /usr/lib and /lib

- distributable one (Adam Richter).
-
- Fixed a bug in ld-linux.so where LD_LIBRARY_PATH and
- LD_PRELOAD were not cleared for setuid/setgid programs.

- Fixed a bug in libdl where dlsym would not return the
- correct address of a symbol if it was redefined in another
- library (Oleg Kibirev).
-
- Changed ld-linux.so to use the following order to search
- for libraries: LD_{ELF_}LIBRARY_PATH, ld.so.cache, rpath,
- /usr/lib and /lib.

- Fixed a bug in libdl when closing a library (H.J. Lu).
-
-Changes in version 1.6.2:
-
- Changed the error message printed by ldd when a file is
- not a.out or ELF. It used to only list a.out formats.
-
- Changed ldconfig to no longer cache and set up links for
- ld-linux.so.
-
- Changed ld-linux.so and libdl to not conflict with upcoming
- changes in kernel header files.
-
- Changed ld-linux.so to not print preloaded libraries.
-
-Changes in version 1.6.1:

- Changed ldconfig to use stdout instead of stderr when
- printing the cache.
-
-Changes in version 1.5.3:
-
- LD_PRELOAD enhancements (Tristan Gigold).
-
- LD_PRELOAD patch for linux-68k (Andreas Schwab).
-
-Changes in version 1.5.2:
-
- More ELF changes (Mitch D'Souza).
-
- Changed ldconfig to also update the link for ld-linux.so.
-
-Changes in version 1.5.1:
-
- More ELF and LD_PRELOAD changes (Mitch D'Souza).
-
-Changes in version 1.5.0:
-
- Chnaged all executables to QMAGIC (Mitch D'Souza and Rick
- Sladkey).
-
- Added preliminary support for ELF to ldd and ldconfig (Eric
- Youndale and H.J. Lu).
-
- Added support for LD_PRELOAD to ld.so (Mitch D'Souza).
-
- Removed the "advertising" clause from the copyright notices
- in all source files.
-
-Changes in version 1.4.4:
-
- Changed ldconfig to support QMAGIC libraries.
-
- Fixed a bug in ld.so where some of the error messages had
- transposed arguments.
-
-Changes in version 1.4.3:
-
- Fixed an obscure bug in ld.so where an index was not being
- incremented when a library was not found using the cache.
-
-Changes in version 1.4.2:
-
- Changed ldconfig to issue a warning and continue instead
- of an error and exiting when a link can't be updated.
- This is useful when some libraries are imported on read-
- only file systems, such as an NFS mounted /usr.
-
- Changed ld.so to be more robust in searching for libraries.
- A library is not considered found unless it can actually be
- loaded. If a library is not found using the cache, the
- standard directories are searched as in pre-cache versions.
-
-Changes in version 1.4.1:
-
- Fixed minor Makefile problems.
-
- Added support for linux-68k.
-
- Fixed a bug in ld.so where libraries with absolute paths
- were not handled correctly.
-
- Changed ld.so to ignore the directory in the names of
- shared libraries by default. This allows older libraries
- with absolute paths, such as the XView libraries, to take
- advantage of the cache support.
-
- Added a minimal usage message to ldconfig.
-
-Changes in version 1.4:
-
- Fixed bug in ld.so where minor version numbers were not
- reported correctly when a minor version incompatibility
- was found.
-
- Fixed bug in ldconfig where libraries with subversion
- numbers greater than 9 were not compared correctly.
-
- Added Mitch D'Souza's support for suppressing warning
- messages from ld.so about minor version incompatibilities.
-
- Added Mitch D'Souza's support for using a cache to speed
- up searching for libraries in the standard directories.
-
- Added Mitch D'Souza's support for a debugging version of
- ld.so. Link with -lldso if you think you are experiencing
- dynamic linker problems.
-
-Changes in version 1.3:
-
- Added support for libraries using absolute pathnames. If I
- had known that the XView libraries used them, I would have
- added this earlier.
-
- Fixed a bug handling old libraries using a pathname beginning
- with '/' or '/lib/'.
-
-Changes in version 1.2a:
-
- Fixed a minor bug in ldd which caused all files, specifically
- scripts, to be recognized as binaries. Thanks to Olaf Flebbe
- for reporting it.
