Then I'll re-iterate the question of what version of the libtool
scripts and libtool.m4 he's using. Also, what are the libtool-related
macros called in configure.in? Is AC_LIBTOOL_CXX being called
explicitly (it shouldn't), or is it called implicitly by the
AC_PROG_CXX hook?

Robert sent me his generated libtool script. Part of the CXX
configuration is listed below. It appears that ltconfig wasn't
invoked properly. The C++ compiler was not set when configuring the
C++ tagged configuration.
### BEGIN LIBTOOL TAG CONFIG: CXX
# Libtool was configured as follows, on host boreas:
#
# AR="" AR_FLAGS="" LTCC="gcc" CC="" \
# CFLAGS="" CPPFLAGS="" \
# MAGIC="" LD="" LDFLAGS="" LIBS="" \
# LN_S="ln -s" NM="/bin/nm -B" RANLIB="ranlib" STRIP="strip" \
# AS="" DLLTOOL="" OBJDUMP="" \
# objext="" exeext="" reload_flag=" -r" \
# deplibs_check_method="pass_all" \
# file_magic_cmd="\${MAGIC}" \
# make/ltconfig -o libtool --cache-file=/dev/null --with-gcc
--build=powerpc-ibm-aix4.3.3.0 --add-tag=CXX make/ltcf-cxx.sh
powerpc-ibm-aix4.3.3.0
#
BTW, Robert thanks so much for working on the AIX port! I've been
aching to get that port completed but since I don't have access to an
AIX box I've been waiting for someone to come along to help out. :-)

That's the problem. It should be 'g++', in the CXX configuration.
Remove the `tail -1' and make sure you get two lines, one for the
default configuration and one overrider for CXX.
Then go figure why ltconfig got the wrong value when creating the CXX
configuration. Search for `TAG CONFIG: CXX' to see the configuration
variables passed to ltconfig. Also check what version of libtool
you're using.

It doesn't have to be. libtool should be able to infer the tag from
the command line. What do you get if you run:
../../libtool --tag=CXX --config | grep '^CC=' | tail -1

Hi Robert, I only noticed the following after I posted my last message: On Fri, Sep 15, 2000 at 03:37:37PM -0500, Robert Boehne wrote: > libtool: compile: unable to infer tagged configuration > libtool: compile: specify a tag with `--tag' Are you using a C++ compiler different (even if only by name) from the one libtool was configured with? Specifically, is the "CXX" tagged configuration set up to use "c++" or "g++?" The above message implies that the libtool configured compiler and the compiler passed by automake are different. Is this the case? BTW, the above message is coming from the automatic tagged configuration selection code I mentioned in my last message.

This should be transparent. A couple of months ago I added a feature to libtool that automatically selects which tagged configuration to use, even without the "--tag" argument, to specifically handle the situation you describe above. I'll try to reproduce the problem you're getting but I'm fairly certain that this feature was working a few months ago. -Ossama -- Ossama Othman <[EMAIL PROTECTED]> Distributed Object Computing Laboratory, Univ. of California at Irvine 1024D/F7A394A8 - 84ED AA0B 1203 99E4 1068 70E6 5EB7 5E71 F7A3 94A8
Re: multi-language-branch: --tag=CXX not specified
OK, I don't think I was very clear about what exactly my problem is, When I take the Makefile's that result from running automake, and autoconf, and add --tag=CXX to the C++ variable definitions, the error message goes away and it complies a shared library. This tag should be automaticly put into the Makefile but it is not being done. Now I also have some C source files in the project so it needs to which to use C or C++.

libtool.m4, that should be part of aclocal.m4, hooks into AC_PROG_CXX
some code to automatically add a CXX tag to libtool. If you don't use
AC_PROG_CXX or you're using an incompatible libtool.m4, you will get
an error like this.

It's highly outdated, at this point. Basically, you have to modify
ltcf-cxx.sh. Take a look at it and see if it makes any sense for you
:-)
