[Evolution-hackers] libtool madness: creates *.so*T linked against the wrong libs

[Patrick Ohly <Patrick Ohly gmx de>]

Hello,

I try to compile Evolution 2.12.x on Debian Etch, using Paul Smith's
Makefile. I was successful once, but not anymore. The problem is that
"libtool --install" puts e.g. a libebook.so into my installation
directory which was linked against the system's libcamel and not the one
from Evolution 2.12.x.

I traced it down to the install step:

patrick gollum(/scratch/evo-src/evolution-data-server/addressbook/libebook)$ rm .libs/libebook-1.2.so.9.1.0T
patrick gollum(/scratch/evo-src/evolution-data-server/addressbook/libebook)$ /bin/sh ../../libtool --mode=install /usr/bin/install -c  'libebook-1.2.la' '/usr/local/evo-svn/lib/libebook-1.2.la'

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/evo-svn/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
patrick gollum(/scratch/evo-src/evolution-data-server/addressbook/libebook)$ ldd .libs/libebook-1.2.so.9.1.0 | grep camel
        libcamel-1.2.so.10 => /scratch/evo-src/evolution-data-server/camel/.libs/libcamel-1.2.so.10 (0xb7b4d000)
patrick gollum(/scratch/evo-src/evolution-data-server/addressbook/libebook)$ ldd .libs/libebook-1.2.so.9.1.0T | grep camel
        libcamel-1.2.so.8 => /usr/lib/libcamel-1.2.so.8 (0xb7b2c000)

Note how gcc relinks libebook-1.2.so.9.1.0 correctly against
libcamel-1.2.so.10, but then libebook-1.2.so.9.1.0T gets installed. I
had removed that file but libtool must have recreated it - I have no
idea where.

Before I start to dissect the "libtool" script (no, please, please,
spare me), does this look familiar to anyone?
