Hi Jussi,

first of all, thanks for the very quick reply.

So do you mean, $PREFIX/lib must be in your library path or otherwise
added manually? That will work, for sure: If I add $PREFIX/lib to
DYLD_LIBRARY_PATH (MacOS X) or to LD_LIBRARY_PATH (Linux), everything
works fine.

However, allow me a short statement why this is not a good behavior.
Please don't misunderstand this as nagging, I'm glad that you invest
your time and work into cuneiform and I'm grateful to use it as free and
open source software. So please read this as a constructive criticism.

"make" is supposed to create a local binary in the source directory.
This binary includes all the necessary information about where to find
it's dynamical libraries. That works fine with cuneiform 0.8.0 and 0.9.0
equally. According to Unix conventions, "make install" then not only
copies the libs to  $PREFIX/lib and the binaries to $PREFIX/bin but also
ensures that the dynamical libs are found under the new location
$PREFIX/lib by the binary.

cuneiform 0.8.0 obeys to these conventions:

cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_INSTALL_PREFIX=/my/cuneiform08 ..
make
./cuneiform

Cuneiform for Linux 0.8.0
Usage: ./cuneiform[-l languagename -f format --dotmatrix --fax -o result_file] imagefile

make install
/my/cuneiform08/bin/cuneiform

Cuneiform for Linux 0.8.0
Usage: ./cuneiform[-l languagename -f format --dotmatrix --fax -o result_file] imagefile

That's fine. However, cuneiform 0.9.0 unfortunately abandons this
convenient and conventional behavior:

cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_INSTALL_PREFIX=/my/cuneiform09 ..
make
./cuneiform

Cuneiform for Linux 0.9.0
Usage: ./cuneiform [-l languagename -f format --dotmatrix --fax -o result_file] imagefile

make install
/my/cuneiform09/bin/cuneiform

dyld: Library not loaded: libcuneiform.0.9.0.dylib
  Referenced from: /tmp/usr/bin/cuneiform
  Reason: image not found
Trace/BPT trap

Even if you don't consider this a bug, why is this at least undesirable?
It's true: If one uses the standard prefix, this will in most cases
work, as then $PREFIX/lib is in the library path. However, imagine
someone wants to install to /usr/local instead, or into the local home
directory? I don't think common ubuntu users, for instance, will have
any of this in their library path and might be quite confused by the
message shown above.

Moreover, concepts like Macports which rely on standard GNU conventions
are faced with enormous difficulties with such a behavior as in 0.9.0
(the standard prefix of Macports is definitely not in the lib path), not
to mention more exotic Unix systems with quite non-standard packaging
systems.

I would therefore suggest to retain the behavior of version 0.8.0 in
future versions of cuneiform. You will save users who need to compile
themselves or packagers a lot of painstaking work.


Best, 

Tobias

MacOS X: dynamical libraries not found after installation of cuneiform 0.9.0

Status in Linux port of Cuneiform: New

Bug description:
I'm trying to make a Portfile for cuneiform 0.9.0 on MacOS X. Therefore, I need to call make install with non standard prefixes. When I use such a non standard prefix, like this:

cmake -DCMAKE_BUILD_TYPE=debug -DCMAKE_INSTALL_PREFIX=/tmp/usr/ ..
make

everything compiles fine, and

./cuneiform
works:

Cuneiform for Linux 0.9.0
Usage: ./cuneiform [-l languagename -f format --dotmatrix --fax -o result_file] imagefile

However, after

make install

cuneiform is installed into the right directory according to the prefix, but the binary doesn't find it's own dynlibs anymore:

/tmp/usr/bin/cuneiform
dyld: Library not loaded: libcuneiform.0.9.0.dylib
  Referenced from: /tmp/usr/bin/cuneiform
  Reason: image not found

For cuneiform 0.8.0, everything works fine, no matter what prefix I give.
