- .Os
- .Sh NAME
- .Nm check-lib-depends
- .Nd scan port for shared libraries
- .Sh SYNOPSIS
- .Nm check-lib-depends
- .Op Fl fimoqx
- .Op Fl B Ar destdir
- .Op Fl d Ar pkgrepo
- .Op Fl D Ar directory
- .Op Fl O Ar dest
- .Op Fl S Ar VAR Ns = Ns Ar value
- .Op Fl s Ar source
- .Op Ar package ...
- .Sh DESCRIPTION
- .Nm
- scans a port or package for shared libraries, and verify that all of them
- are properly recorded.
- .Pp
- .Nm
- can either scan files from a built port after the
- .Ar fake stage
- from the
- .Ev WRKINST
- directory, or look directly inside a
- .Ar package .
- .Pp
- Likewise, it can also verify dependencies off installed packages,
- or figure them out directly from the port directory.
- .Pp
- .Nm
- actually consists of two distinct stages:
- .Bl -bullet
- .It
- scan all binaries inside a package to extract libraries and rpaths,
- using
- .Xr objdump 1
- or
- .Xr ldd 1 .
- .It
- compare those libraries against the port's registered dependencies
- and report problems.
- .El
- .Pp
- The options are as follows:
- .Bl -tag -width keyword
- .It Fl B Ar destdir
- Scan files under
- .Ar destdir .
- .It Fl d Ar pkgrepo
- Look for all needed packages under directory
- .Ar pkgrepo .
- .It Fl D Ar directory
- Create debug log files under
- .Ar directory
- that show in more details the run of
- .Xr objdump 1 .
- .It Fl f
- Give full reports of every file that requires a missing library.
- .It Fl i
- Read packing-list from standard input.
- .It Fl m
- Always show progress-meter, even if not run from terminal.
- .It Fl o
- Scan binaries using
- .Xr ldd 1 ,
- which also works for old a.out binaries, instead of
- .Xr objdump 1 ,
- which only works for
- .Xr elf 5
- binaries.
- .It Fl O Ar dest
- Save result of first stage in file
- .Ar dest .
- .It Fl q
- Be quiet, do not emit
- .Sq Extra:
- wantlibs unless there's also an actual problem.
- .It Fl S Ar var Ns = Ns Ar value
- recognize list of libraries listed in a variable, and replace said list
- with variable value.
- For instance,
- .Fl S Ar LIBCXX Ns = Ns Ar stdc++
- will replace
- .Sq stdc++
- with
- .Sq ${LIBCXX}
- in
- .Ev WANTLIB
- lists for compatibility with both clang and gcc.
- .It Fl s Ar src
- Don't scan, directly read result of first stage from file
- .Ar src .
- .It Fl x
- Don't show progress-meter, even if run from terminal.
- .El
- .Pp
- If no
- .Ar package
- is given, and the
- .Fl i
- option is used,
- .Nm
- will retrieve the packing-list from stdin, and scan the package according
- to other options.
