Hi All,
I've been trying to compile Ocropus 0.4 for a while now with no
success. There are two problems I encounter.
Issue 1:
./build --with-tesseract=/home/davidt/software/tessercat-2.04 --with-
iulib=/home/davidt/software/iulib/ --prefix=/home/davidt/software/
ocropus-0.4/
This fails with:
checking for exit in -liulib... no
configure: error: no iulib; please install iulib first (see INSTALL)
looking at config.log I get:

I'm not really sure what this error means, however I can hack around
it by commenting out the 'char exit ();' line and changing the 'exit
();' line to be 'exit (0);'. This allows build to compete fine.
Upon issuing 'make' everything goes well for a while and then I get:

make[1]: *** [ocropus] Error 1

make: *** [all-recursive] Error 1
My understanding is that such an error indicates that the linker can't
find iulib, but as you can see its clearly included on the command
line with '-L'.
Given both errors seem to relate to not being able to find iulib I
imagine they're related but I don't really have any idea how to solve
the issue when iulib compiled and checked fine and is clearly
included.
Thanks for the help.
