NAME
|
|
$myname - populate the target root file system
|
|
|
|
SYNOPSIS
|
|
$myname OPTIONS -s source_root -d destination_root
|
|
|
|
DESCRIPTION
|
|
$myname will 'populate' your target root file system ('src_dir') with
|
|
libraries from the toolchain (eg. libc.so...), storing the result into
|
|
'dst_dir'.
|
|
|
|
OPTIONS
|
|
-s src_dir
|
|
use 'src_dir' as the un-populated (source) root directory
|
|
|
|
-d dst_dir
|
|
use 'dst_dir' as the place to put the populated root directory
|
|
|
|
-l name1[:name2[...]]
|
|
Always add the specified shared library/ies name1, name2... from the
|
|
toolchain (in the sys-root). Actual library names are searched as
|
|
follows (where 'name' is replaced with the given name) in the
|
|
sys-root directory:
|
|
- libname.so
|
|
- name.so
|
|
- name
|
|
If the file is found, then the SONAME of the library is used, and the
|
|
library is copied with that name. If the library was not found, this
|
|
yields an error (unless -f was given).
|
|
|
|
-L file
|
|
Read 'file' for a list of shared libraries to always add from the
|
|
toolchain. The file should contain one library name per line; text
|
|
after a # is ignored until the end of the line; spaces are ignored;
|
|
empty lines are ignored. Libraries are searched for as with -l.
|
|
|
|
-f force execution: if destination directory already exists, it will be
|
|
removed first; if a specified library (above) was not found, continue.
|
|
|
|
-v Be verbose
