Hi, Ralf.

Yes, I do exactly this already. On a Linux machine the invocation I use is:

==================================================
$ sh ./autogen.sh # wrapper to the autotools.
$ mkdir build && cd build
$ ../configure --prefix="$PWD/installedqdvi" QTDIR='/usr/local/Qt4'
$ make
==================================================

which works perfectly.

Also works.

==================================================
$ (cd build && make maintainer-clean)
$ rm -fr build
$ sh ./autogen.sh
$ mkdir build && cd build
$ ../configure --prefix="$PWD/installedqdvi" QTDIR='/usr/local/Qt4'
$ make dist
...
tardir=qdvi-4.0cvs && /bin/sh /home/angus/qdvi/trunk/config/missing --run tar 
chof - "$tardir" | GZIP=--best gzip -c >qdvi-4.0cvs.tar.gz
tardir=qdvi-4.0cvs && /bin/sh /home/angus/qdvi/trunk/config/missing --run tar 
chof - "$tardir" | bzip2 -9 -c >qdvi-4.0cvs.tar.bz2
{ test ! -d qdvi-4.0cvs || { find qdvi-4.0cvs -type d ! -perm -200 -exec chmod 
u+w {} ';' && rm -fr qdvi-4.0cvs; }; }

$ ls
boost   config.log     include  libtool   msvc  qdvi-4.0cvs.tar.bz2
config  config.status  lib      Makefile  qdvi  qdvi-4.0cvs.tar.gz
==================================================

The problem is with "make distcheck" which fails with:

==================================================
$ make distcheck
...

==================================================

It fails because "make all" visits the qdvi/kdelibs subdirectory and generates 
kconfig_compiler before returning to the qdvi directory where it is actually 
used. "make distcheck" doesn't visit the qdvi/kdelibs subdirectory first.

You can see the offending Makefile.am here:
http://cvs.sourceforge.net/viewcvs.py/qdvi/qdvi/qdvi/Makefile.am?view=markup

Adding
  DIST_SUBDIRS = $(SUBDIRS)
as Harlan suggested has no apparent effect.
