All of the changes to readline's config.h were created by the ./configure in 
readline's directory - I didn't edit anything myself (I don't actually have 
much idea of what these options mean.)

I do have a "termcap.h" in /usr/include/ncurses/. (I found this using 
"locate"), and octave's configure does find it. How do I found out if 
/usr/include is in the compile path? Also, I see that configure describes my 
fortran libraries as 
 Fortran libraries: -lg2c -lm 
-L/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66 
-L/usr/i386-redhat-linux/lib -lm
but neither of the redhat directories exists - there is only a 
i586-mandrake-linux directory. Could this be part of the same problem?

I did test this quite carefully - I copied the tree to a new directory, and 
run the top level "make clean".Then I uninstalled the 
zlib1-devel-1.1.3-15mdk.rpm and ran "./configure" and "make liboctave". 
Compile failed.
Once again I ran "make clean". I reinstalled zlib1-devel-1.1.3-15mdk.rpm and 
then ran "./configure". Running "make liboctave" completed, as described in 
the previous email (I repeated these steps as I wrote this).

Here is a list of the files in zlib1-devel:
/usr/include/zconf.h
/usr/include/zlib.h
/usr/include/zutil.h
/usr/lib/libz.a
/usr/lib/libz.so
/usr/share/doc/zlib1-devel-1.1.3
/usr/share/doc/zlib1-devel-1.1.3/ChangeLog
/usr/share/doc/zlib1-devel-1.1.3/README
/usr/share/doc/zlib1-devel-1.1.3/algorithm.txt
/usr/share/man/man3/zlib.3.bz2

If you have any other tests you would like me to run, please let me know.

bye
Thomas
