unixware 7

[jgarriga@saincotrafico.com]

Hi,
  I want to use xvnc in a SCO Openserver Unixware 7.1.1, and I have the
  next compilation problem:

  The first step is well performed
  xmkmf
  make World

  But when I compiled the Xvnc :
  cd Xvnc
  make World

  I got the following messages at the end:
  rm -f libvnc.a
  /usr/ccs/bin/ar cq libvnc.a init.o sockets.o kbdptr.o cmap.o draw.o

  written to Xvnc
  *** Error code 1 (bu21)
  UX:make: ERROR: `all' not remade because of errors (bu14)

  And of course the Xvnc binary is not created.
  I read the same problem in the list (august 2000) but I don4t find the
  solution.
  Could somebody help me?
  In advance thank you
