* demo/Makefile.am: Add helldl, made from dlmain.c, to demostrate
|
||||
`-dlopen' usage.
|
||||
|
||||
* demo/dlmain.c: New file to demonstrate preloaded modules.
|
||||
|
||||
* ltmain.sh.in (link): Add `-dlopen' flag to preload dynamic
|
||||
modules, even on static platforms. Use `$NM' and
|
||||
`$global_symbol_cmd' to extract symbols from required files.
|
||||
(dlname): Delete dlname mode entirely. It is rendered obsolete
|
||||
because the `.la' file format is now a public interface.
|
||||
|
||||
* ltconfig.in (NM): New variable for BSD-compatible nm program.
|
||||
(global_symbol_cmd): Pipeline to extract global symbols from the
|
||||
nm output.
|
||||
|
||||
* ltmain.sh.in: The .la file header should depend on `ltmain.sh',
|
||||
not `$PROGRAM'.
|
||||
(link): Make sure $export_dynamic_flag is eval'ed before it is
|
||||
used.

NEWS - list of user-visible changes between releases of GNU libtool.
|

|
||||
New in 1.0a:
|
||||
* Bug fixes.
|
||||
* Full support for dynamically loaded modules, even on static-only
|
||||
platforms, via a new `-dlopen' link flag.
|
||||
* New tests for a BSD-compatible `nm' program, required for dlopened
|
||||
modules.
|
||||
* FIXME: Deleted `dlname' mode, now that the internal structure of `.la'
|
||||
files is a public interface.
|
||||
|
||||
New in 1.0:
|
||||
* Bug fixes.
|
||||
* Better configuration test to find the system linker. The old test
