kpathsea libraryNot all TeX distributions install the
kpathsea library, even though they install
applications built with it, and the texmf.cnf
configuration file which controls it.
If the library does not appear to be in your
distribution, then you can obtain and build it yourself.
The library is distributed as part of the
web2c (Unix TeX source) distribution, which
you can find at
<ftp://ftp.tug.org/tex/web2c.tar.gz>, or mirrored
on CTAN sites (for example at
<http://www.tex.ac.uk> in directory systems/web2c).
Take a copy of the library (this is a big
distribution), and unpack it. Go into the
kpathsea directory and do the usual
`./configure; make; make install' routine.
With (some?) older distributions of the library this
appeared not to work, and you had to go to the parent of
the kpathsea directory, delete the web2c
directory (which is the bulk of the distribution), then
configure and build it as usual, ignoring the warnings
about the missing main texmf tree.
