build shared versions of libraries
building defaults to off until clang is updated. current clang does not handle -shared, necessary to change the ld invocation to build shared libraries properly. a new clang should be installed and MKPIC defaults to no unless the newer clang is detected. changes: . mainly small imports of a Makefile or two and small fixes (turning things back on that were turned off in Makefiles) . e.g.: dynamic librefuse now depends on dynamic libpuffs, so libpuffs has to be built dynamically too and a make dependency barrier is needed in lib/Makefile . all library objects now have a PIC (for .so) and non-PIC version, so everything is built twice. . generate PIC versions of the compat (un-RENAMEd) jump files, include function type annotation in generated assembly . build progs with -static by default for now . also build ld.elf_so . also import NetBSD ldd

.Sh NAME
|
||||
.Nm ldd
|
||||
.Nd list dynamic object dependencies
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Fl o
|
||||
.Op Fl f Ar format
|
||||
.Ar program ...
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
displays all shared objects that are needed to run the given program.
|
||||
Contrary to
|
||||
.Xr nm 1 ,
|
||||
the list includes
|
||||
.Dq indirect
|
||||
dependencies that are the result of needed shared objects which themselves
|
||||
depend on yet other shared objects.
|
||||
Zero, one or two
|
||||
.Fl f
|
||||
options may be given.
|
||||
The argument is a format string passed to
|
||||
.Xr rtld 1
|
||||
and allows customization of
|
||||
.Nm ldd Ns 's
|
||||
output.
|
||||
The first format argument is used for library objects and defaults to
|
||||
.Qq "\et-l%o.%m =\*[Gt] %p\en" .
|
||||
The second format argument is used for non-library objects and defaults to
|
||||
.Qq "\et%o =\*[Gt] %p\en" .
|
||||
.Pp
|
||||
These arguments are interpreted as format strings a la
|
||||
.Xr printf 3
|
||||
to customize the trace output and allow
|
||||
.Nm
|
||||
to be operated as a filter more conveniently.
|
||||
The following conversions can be used:
|
||||
.Bl -tag -width xxxx
|
||||
.It \&%a
|
||||
The main program's name
|
||||
.Po also known as
|
||||
.Dq __progname
|
||||
.Pc .
|
||||
.It \&%A
|
||||
The value of the environment variable
|
||||
.Ev LD_TRACE_LOADED_OBJECTS_PROGNAME
|
||||
in a.out and the program name from the argument vector from elf.
|
||||
.It \&%o
|
||||
The library name.
|
||||
.It \&%m
|
||||
The library's major version number.
|
||||
.It \&%n
|
||||
The library's minor version number (a.out only, ignored in elf).
|
||||
.It \&%p
|
||||
The full pathname as determined by
|
||||
.Nm rtld Ns 's
|
||||
library search rules.
|
||||
.It \&%x
|
||||
The library's load address
|
||||
.El
|
||||
.Pp
|
||||
Additionally,
|
||||
.Sy \en
|
||||
and
|
||||
.Sy \et
|
||||
are recognized and have their usual meaning.
|
||||
.Pp
|
||||
The
|
||||
.Fl o
|
||||
option is an alias for
|
||||
.Fl f
|
||||
.Ar \&%a:-l\&%o.\&%m =\*[Gt] \&%p\en ,
|
||||
which makes
|
||||
.Nm
|
||||
behave analogously to
|
||||
.Ic nm Fl o .

.Sh HISTORY
|
||||
A
|
||||
.Nm
|
||||
utility first appeared in SunOS 4.0, it appeared in its current form
|
||||
in
|
||||
.Nx 0.9a .
|
||||
.Sh BUGS
|
||||
The
|
||||
a.out
|
||||
.Nm
|
||||
actually runs the program it has been requested to analyze which in specially
|
||||
constructed environments can have security implications.
