  24 # Workaround for "the pixman problem" with netbsd-5 native X. The
  25 # problem is that if the order of rpath options isn't right when
  26 # linking client programs (right being /usr/pkg before /usr/X11R7),
  27 # the native pixman library gets pulled in instead of the pkgsrc one,
  28 # and then the link fails with undefined symbols from cairo; these are
  29 # symbols that are present only in the newer pkgsrc pixman. The
  30 # problem with rpath options and ordering is complicated by there
  31 # being multiple ways of writing them (-R, -Wl,-rpath, etc.) and as
  32 # many packages just blat out flags from various sources they don't
  33 # necessarily match or come out in the right order.
  34 #
  35 # Some cases of "the pixman problem" were solved with one set of
  36 # changes a month ago or so, but other packages still fail for the
  37 # reasons cited. In the absence of a wrappers-based general solution
  38 # to keep the order correct, most or all remaining instances can be
  39 # solved by explicitly adding the necessary pixman lib to the link
  40 # line instead of pulling it in via cairo's dependency on it. Or at
  41 # least, this fixes the build. It should also make the right things
  42 # happen during library search (I think) but that's less clear. I hate
  43 # ELF.
  44 #
  45 # The best way to explicitly add pixman to the link line is to hack it
  46 # into cairo's .pc file. This is what we do here.
  47 #
  48 # Note that this hack is also required for 5.99 earlier than whatever
  49 # point the necessary updates to X were applied. I'm assuming this is
  50 # old enough that nobody's going to care.
