tlbuild: xdvik package
6.5.3 The 'xdvik' package in 'texk/xdvik'
-----------------------------------------
This package is maintained as part of the TeX Live tree with sources in
its own directory ('texk/xdvik/'). The fragment
'xdvik/ac/withenable.ac' contains
dnl extra_dirs = texk/xdvik/squeeze
KPSE_ENABLE_PROG([xdvik], [kpathsea freetype2], [x])
m4_include(kpse_TL[texk/xdvik/ac/xdvik.ac])
thus specifying dependencies on the 'kpathsea', 'freetype', and X11
libraries. The M4 comment (following 'dnl') signals the subsidiary
'squeeze/configure.ac'. This is needed because the main executable
'xdvi-bin' (to be installed as, e.g., 'xdvi-xaw') is for the 'host'
system whereas the auxiliary program 'squeeze/squeeze' has to run on the
'build' system; in a cross compilation, these differ.
The additional fragment 'ac/xdvik.ac' is also included by
'configure.ac' and supplies the configure option '--with-xdvi-x-toolkit'
also seen at the top level.
