Unable to find files
....................

  If a program complains it cannot find fonts (or other input files),
any of several things might be wrong.  In any case, you may find the
debugging options helpful.  Note: Debugging.

   * Perhaps you simply haven't installed all the necessary files; the
     basic fonts and input files are distributed separately from the
     programs.  *Note unixtex.ftp::.

   * You have (perhaps unknowingly) told Kpathsea to use search paths
     that don't reflect where the files actually are.  One common cause
     is having environment variables set from a previous installation,
     thus overriding what you carefully set in `texmf.cnf' (Note:
     Supported file formats).  System `/etc/profile' or other files
     such may be the culprit.

   * Your files reside in a directory that is only pointed to via a
     symbolic link, in a leaf directory and is not listed in `ls-R'.

     Unfortunately, Kpathsea's subdirectory searching has an
     irremediable deficiency: If a directory D being searched for
     subdirectories contains plain files and symbolic links to other
     directories, but no true subdirectories, D will be considered a
     leaf directory, i.e., the symbolic links will not be followed.
     Note: Subdirectory expansion.

     You can work around this problem by creating an empty dummy
     subdirectory in D. Then D will no longer be a leaf, and the
     symlinks will be followed.

     The directory immediately followed by the `//' in the path
     specification, however, is always searched for subdirectories,
     even if it is a leaf.  Presumably you would not have asked for the
     directory to be searched for subdirectories if you didn't want it
     to be.

   * If the fonts (or whatever) don't already exist, `mktexpk' (or
     `mktexmf' or `mktextfm') will try to create them.  If these rather
     complicated shell scripts fail, you'll eventually get an error
     message saying something like `Can't find font FONTNAME'. The best
     solution is to fix (or at least report) the bug in `mktexpk'; the
     workaround is to generate the necessary fonts by hand with
     Metafont, or to grab them from a CTAN site (*note unixtex.ftp::).

   * There is a bug in the library. Note: Reporting bugs.
