28 $myname will 'populate' your target root file system ('src_dir') with
29 libraries from the toolchain (eg. libc.so...), storing the result into
34 use 'src_dir' as the un-populated (source) root directory
37 use 'dst_dir' as the place to put the populated root directory
40 Always add the specified shared library/ies name1, name2... from the
41 toolchain (in the sys-root). Actual library names are searched as
42 follows (where 'name' is replaced with the given name) in the
47 If the file is found, then the SONAME of the library is used, and the
48 library is copied with that name. If the library was not found, this
49 yields an error (unless -f was given).
52 Read 'file' for a list of shared libraries to always add from the
53 toolchain. The file should contain one library name per line; text
54 after a # is ignored until the end of the line; spaces are ignored;
55 empty lines are ignored. Libraries are searched for as with -l.
57 -f force execution: if destination directory already exists, it will be
58 removed first; if a specified library (above) was not found, continue.
