Versioning of Shared Objects.
|
||||
|
||||
QUICK OVERVIEW
|
||||
|
||||
For a shared object to be versioned the following needs to be done:
|
||||
|
||||
* Version strings consist of 3 parts and a dot: The string "sgi",
|
||||
a decimal number (the major number), a dot, and a decimal number
|
||||
(the minor number).
|
||||
|
||||
* Add the command -set_version sgi1.0 to the command to build
|
||||
the shared object (cc -shared, ld -shared, etc.).
|
||||
|
||||
* Whenever you make a COMPATIBLE change update the minor version
|
||||
number (the one after the dot), and add the latest version string
|
||||
to colon-separated list of version strings, e.g., -set_version
|
||||
sgi1.0:sgi1.1:sgi1.3
|
||||
|
||||
* Whenever you make an INCOMPATIBLE change, update the
|
||||
major version number. Pass this as the version list, e.g.,
|
||||
-set_version sgi2.0. Change the filename of the OLD shared object
|
||||
by adding a dot followed by the previous major number to the filename
|
||||
of the shared object. DO NOT CHANGE the soname of the object.
|
||||
No change to the file contents are necessary or desirable. Simply
|
||||
rename the file.
|
||||
|
||||
* Inter-library dependencies should be fully tracked by libtool.
|
||||
Reminded by Alexandre Oliva. This requires looking up installed
|
||||
libtool libraries for transparent support.
|
||||
|
||||
* Get rid of the sections that try to change behaviour for GNU ld. We
|
||||
really should make our shared library support just depend on the
|
||||
compiler type.
|
||||
|
||||
* Alexandre Oliva suggests that we hardcode paths into libraries, as
|
||||
well as binaries: `... -Wl,-soname -Wl,/tmp/libtest.so.0 ...'.

When people report bugs, ask them to use the @samp{--config},
|
||||
@samp{--debug}, or @samp{--features} flags, if you think they will help

you. These flags are there to help you get information directly, rather

than having to trust second-hand observation.

@item
|

Rather than reconfiguring libtool every time I make a change to
|
||||
@code{ltconfig.in} or @code{ltmain.in}, I keep a permanent
|
||||
@code{libtool} script in my @var{PATH}, which sources @code{ltmain.in}
|
||||
directly.
|
||||
|
||||
The following steps describe how to create such a script, where
|
||||
@code{/home/src/libtool} is the directory containing the libtool source
|
||||
tree, and @code{/home/src/libtool/libtool} is a libtool script that has
|
||||
been configured for your platform, and :

||||
|
||||
@example
