About a week ago I posted this massage to the libtool mailing but I have
yet to receive any replies.
I could REALLY use some help here. I understand I am using a
developmental version and will be willing to work with you to help improve
libtools.
Maybe I should just not use the CXX language features and just some how
make sure all the right libraries get linked in and just avoid using
global variables which require initilization...
Please give me some guidance here.

Subject: Shared libraries w/ C++ and libltdl.

I am having all sorts of problems with shared libraries and C++ with the
multi-lang. branch.
PROBLEM 1
1) On many platforms libtool can create shared libraries for C but not for
C++
2) On many of the platforms which libtool does know how to create C++
shared libraries libstdc++ is not compiled as a shared library, nor is it
compiled with PIC support. This means that linking the shared library
fails miserably because it will try to link the non PIC code into the
shared library.
So my question is
1) Is there a way to force libtool NOT to link it as a C++ library if it
can't do it as a shared library. IE don't fall back to only making a
static library.
2) Is there a way to force libtool NOT to link in libstdc++ but STILL link
it using c++?
In either case I would like the C++ libraries to be specified in the .la
files so that they will get statically linked in by libtool when a C program
uses my libraries.
PROBLEM 2
Is they a way to do the ldpreloding stuff that is 100% transparent to
programs linking with my libraries using libtool? I want the end user to
have to doing noting but "libtool --mode=link ... -l<My library>" and have
libtool automatically preload the necessary modules and set up the data
structure automatically so that the end user does NOT have to call
LTDL_SET_PRELOADED_SYMBOLS().
Thanks in advance. Any advice you can give me would really help me out
with my Pspell (http://pspell.sourceforge.net) project.
