llvm dev - Oct 2004 - [LLVMdev] RESOLVED: [LLVMbugs] [Bug 451] Libtool does not create libNAME.$(SHLIBEXT) files when building dynamic libs

I'm forwarding this bug resolution because it has a pretty wide impact on
LLVM
developers. This bug (451) has been resolved (well, works for me anyway). If 
you have reconfigured your build tree since October 4th, you need to 
reconfigure again. The bug produced shared objects that don't have a .so 
extension. Reconfiguring will fix this problem. The notes below show what was 
needed to be fixed.

FOR THOSE RUNNING AutoRegen.sh:

For this to work reliabily, you MUST have the following auto* tools in your
path:

autoconf: 2.59
aclocal: 1.9.2
autoheader: 2.59
automake: 1.9.2
libtool: 1.5.10

Other combinations *might* work, but its unlikely (I've tested nearly all of
them). Note that automake isn't needed by AutoRegen.sh UNLESS you're
trying out
the --with-automake flag (on AutoRegen.sh). However, you still MUST install 
automake 1.9.2 even if you're not using --with-automake because that is how
you
get aclocal 1.9.2 which is needed by autoconf.

The difficulty I had turned out to be the name of "mklib" instead of
"libtool".
The Makefiles use "mklib" but I was constantly regenerating libtool
under
various circumstances. The real problem was our version of ltmain.sh which
didn't match our version of libtool.m4. Both these files have been committed
as
well as changes to the AutoRegen.sh script. Commits are here:

Bug resolved.

NOTES FOR FUTURE:

When upgrading the version of libtool, you must do the following:

1. configure/build/install libtool with --prefix=<PFX>
2. Copy <PFX>/share/aclocal/libtool.m4 to llvm/autoconf/m4/libtool.m4
3. Copy <PFX>/share/libtool/ltmain.sh to llvm/autoconf/ltmain.sh
4. Adjust the llvm/autoconf/m4/libtool.m4 file to ensure that the variable
    default_ofile is set to "mklib" instead of "libtool"
5. Possibly adjust llvm/autoconf/m4/libtool.m4 to get rid of autoconf
    warnings related to obsolete autconf features (e.g. AC_TRY_LINK)
