XThis is an experimental implementation of shared libraries for 386BSD. This
Ximplementation has the following properties:
X
X - No kernel extension is necessary. Just the shared libraries need to be
X installed in order to run programs using them.
X
X - The shared libraries follow the approach used in System V: Shared libraries
X are linked to fixed addresses and mapped in the address space at this
X fixed address.
X There are no symbols resolved at load-time as in AIX 3.x and SunOS.
X
X - This package includes makefiles and programs that create shared version of
X the C and X11 libraries and an extended version of the startup file crt0.o
X
X - It also includes patches for the cc and g++ commands in order to link to
X the shared version of the libc unless started with "-static". The shared
X version of the libX11 must be explicitly specified as "-lX11_s".
X
X
XThe package is installed like this:
X===================================
X
X log-in as root and type
X
X make
X make install
X make patch
X
XThe first make creates the shared libraries. The second make creates the direc-
Xtory /shlib and copies the shared libraries in there. It also installs the
Xfiles crt0_s.o, libc_s.a, and libX11_s.a in directory /usr/lib. The third make
Xpatches, recompiles and installs the commands cc and g++. It assumes the source
Xcode for cc and g++ installed in /usr/src/usr.bin/.
X
XIf you don't have X11 installed, you might want to remove "libX11" from the
Xtop-level makefile before starting the installation.
X
X
XDeinstalling the package
X========================
X
XIn order to get rid of this shared library package, log-in as root and type
X
Xeither
X make deinstall
Xto switch back the the old cc and g++ programs that link statically
X
Xor
X make remove
Xto switch back as above and to remove the files in /usr/lib needed for linking
Xto shared libraries
X
Xor
X make remove-all
Xto do all the above and to remove all shared libraries. After make remove-all,
Xall programs linked to shared libraries won't run anymore.
X
X
XLinking to Shared Libraries
X===========================
X
XThe main requirement to keep in mind when using shared libraries is that all
Xreferences in shared libraries must be resolved within the same or another
Xshared library.
X
XPrograms that undump their data segment, notably GNU emacs and MIT scheme, don't
Xrun when linked with shared libraries.
X
X
XCreating a Shared Library
X=========================
X
XA shared library can be created by making a directory, adding the directory
Xname to the top-level makefile and setting up the files
X Makefile
X mkshlib
X sharedlibs.c
Xin the directory.
X
XThere are some topics to decide upon:
X - text and data segment address
X - existing shared libraries used by the new shared library
X - version number of shared library
X
XBoth existing libraries, libc and libX11, can be consulted as examples for
Xthese topics.
X
X
XTODO
X====
X
XA few extensions are highly desirable. The main limitation of the current
Xappoach is that after any change to some functions in a library its sharable
Xlibrary is very likely to differ in some of its exported addresses. Therefore,
Xeither the old shared library has to stay around or all programs using it need
Xto be relinked.
X
XThere are some extensions that make the addresses exported by a shared library
Xless dependent on the library's internals:
X
X - Use a branch table for all globally accessible functions included in the
X library. The addresses of the branches are exported. They don't change when
X any function changes size.
X
X - Don't export all symbols, accept a list of symbols to export. Most symbols
X in the data segment don't need to be exported.
X
XAnyway, it's working as is. Maybe there's any volounteer willing to do the
Xextensions.
X
XEnjoy,
X Joerg
