this will be used for ldb module loading
|
|
In this case we test if the -Wl,-h,%s works and if so use this form

On Solaris with sun studio compiling an executable with -liconv even if
there is no libiconv.so or libiconv.a will work but not for a shared
lib.
This problem leads to build problem as the linker won't be able to find
libiconv when building shared lib as liconv is wrongly specified

we need to incorporate the module objects too
|
|
these aliases are no longer needed, and can cause a lot of confusion
|
|
this is needed for the symbols.py extension

give a clear error on an unknown dependency in a grouping library

we still need the STATIC_xx_MODULES define when there are no static
modules. It contains just the sentinal.

this is part of an effort to reduce the amount of automatic dependency
munging we do. When working on the correct dependency tree for Samba
it is easier to add the right dependencies in the wscript files than
rely on them being added by the waf rules. This change removes the
automatic dependency of modules on their subsystem. Many modules don't
actually need this dependency anyway, so it is better to add it where
they are needed (for example, for ldb modules)

this adds checking of the symbols in all our object files, libraries
and syslibs. It will form the basis in future for a lot more checks,
but for now it just checks basic rules like not allowing us to use
symbols that are in system libs.
Currently this is enabled only if you use the --symbol-check option,
(or use make with SYMBOLCHECK=1) but I intend to make this always
enabled once it has had more testing.

this makes it easier to perform symbol checking before the link
stage. The two new build groups symbolcheck and syslibcheck will be
used by the symbols.py extension
|
|
this produces clearer output on errors
|
|
when we display a rule with no inputs, just call the original display
function

this is a useful function for the new symbols code, so separate it out
of samba_deps.py

when we detect a library loop, try to display the paths between the
two libraries. This should make it easier to fix.

this makes it easier to add project rules that are only run in

this should solve a problem with creating alias modules with Sun CC.
Thanks to Matthieu for the idea, and Thomas for the waf code

It's sometimes needed to specifiy the soname directly.

moved it out of the general waf build as the s3 waf build cannot yet
handle linking with -Wl,-no-undefined

the pidl generated python code can generate dependencies between two
python modules, so we have to allow this for now
|
|
this is rather strange, but we get build errors without it. There may
be a bug in the waf python tool, or I may misunderstand how to use it
|
|
this flag was not being propogated to our link rules, so we were not
in fact enforcing no undefined symbols in libraries.

it is never correct to list a dependency on a python module

this prevents a loop between SOCKET_WRAPPER and replace in the s3 waf
build
|
|
'private_library' better captures what we are trying to get at when we
bundle a library
|
|
a grouping library is one which 'groups' a set of subsystems. This
means that if a target depends on a subsystem that is within a
grouping library then that dependency is replaced with a dependency on
the grouping library.
This gives us a powerful method to avoid duplicated object files
between libraries.

this fixes a problem with libnss_winbind.so.2. Thanks to Jelmer for
spotting this.
|
|
we now create a base library, and then create the alias modules as
wrappers around that base. That prevents double instantiation of any
object files in the modules

these do not need to be expanded in break_dependency_loops()
|
|
this is for libraries where we make no promises about the API, but
where we wish it to be a library to allow our binaries to use common
code.
These libraries always get the project suffix added to the library
name, to ensure we are in a separate namespace
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>

make the variable names a lot clearer, and restrict the expansion of
subsystem deps to object style subsystems and modules. If a subsystem
or a module is built as a library then we don't need to expand the
dependencies across that boundary
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
|
|
these options make it easier to examine our depenency tree, by showing
any objects linked into more than one library, and by showing the
dependency tree for a chosen target
|
|
|
|
this prevents an install triggering a new check of the project rules
on the next build

this should help with MacOSX .dylib libraries
