Revision 1.1 - (show annotations) (download) (as text)
Wed Oct 10 01:20:09 2001 UTC (17 years, 6 months ago) by ite
Branch: MAIN
CVS Tags: HEAD
File MIME type: text/x-chdr
* Refactored the tree (especially src/modules.c) to use the libltdl
  wrapper. Modules are configured to be lt_dlopened or dl_preopened (if
  the system doesn't support shared libraries).
* Should compile modules on more SunOs environments and on Beos too.
* Libtoolized the package: modules and internal libraries build system
  more protable than ever.
* Wiped out old makefiles in favour of automake and Makefile.am's
  files.
* Misc cleanups.
* Updated bootstrap script
* Moved doc/AUTHORS to ./AUTHORS
* Updated config.guess and config.sub
* Changed misc/ to ./ temporairly
* Got rid of misc/modconfig, and more in general of the old module
  configuration stuff, in favor of an incoming ./configure parametrized
  choice.
* Moved configure macros from aclocal.m4 to acinclude.m4 since aclocal.m4
  is now generated by aclocal on bootstrap.
* Removed no more necessary macros like EGG_EXEEXT because of
  libltdl+automake power ;P
* Removed EGG_CHECK_LIBSAFE_SSCANF macro that wasn't necessary anymore
  after gettext support.
* Added preliminary EGG_DEBUG_OPTIONS macro.
* Heavily stripped EGG_CHECK_OS macro and got rid of some system
  specific defines that were dead because of libltdl.
* Updated .cvsignore files.
* Improved make dist target.
* make static is gone in favor of ./configure --disable-shared.
* make debug is gone in favor of future ./configure --with-debug
  options.
* Others targets are gone in favor of more GNU standard targets.
* Updated po/eggdrop.pot.
# Egglib is now compiled and linked in the core.
* Moved compress.mod's specific configure macros to the top configure script.
* Switched to gettext 0.10.40 and pre-gettextized the devel tree.
