dvipng: Installation outside the texmf tree
2.4 Installation outside the texmf tree
=======================================
In some cases, a dvipng binary installed outside the texmf tree will not
be able to find virtual fonts, or the PostScript font maps (normally
used by dvips). This may be because _only_ $SELFAUTOLOC, $SELFAUTODIR,
and $SELFAUTOPARENT are used in the texmf tree configuration file
'texmf.cnf'. If so, give the switch '--enable-selfauto-set' to
'./configure'. This will make dvipng adjust these three internally so
that kpathsea thinks that dvipng _is_ installed in the texmf tree.
