Where can I get the qt documentation ?

Documentation is located in the binary release and also online. See doc.trolltech.com

qt3 from cvs failes to compile ?

If you check out qt from CVS you have to first issue an 'make -f Makefile.cvs'. This generates the missing symbolic links to the header files.

The next step is to configure with the correct options. You can use the script config.cygwin-thread. This seems to be needed for KDE 3.x.

The next problem I had was linking. If it's missing the Library libdl.a, you can create a symbolic link to /lib/libcygwin.a in /lib or /usr/lib. This fakes the ld library. Alternatively you can also remove the -ldl option from mkspecs/cygwin-g++/qmake.conf.

(Note: Current cvs releases already contains the last mentioned fix)

For additional informations about compiling see the compiling page.

How do I configure printing with qt ?

QT by default uses the lp command for printing, so the current qt printing support provides this command by using the ghostscript interpreter.

QT/cygwin releases newer than 3.2.3-3 already have installed the printer support, but for older releases, see the following steps:

• Copy and paste the following command into a bash shell, than press RETURN and CTRL-D to close the cat command:

   
  $ cat >/opt/qt/3.2/bin/lp
  #!/bin/sh
  PRINTER="\\\\ntserver02\\BrotherH"
  #PRINTER="lpt1:"
  PRINTER_TYPE=deskjet
  PAPER_SIZE=a4
  
  LOG_FILE=/var/log/$0.log
  INFILE=/tmp/$0.1$$
  TMPFILE=/tmp/$0.2$$
  
  # save data into temporary file 
  cat >>$INFILE
  
  # convert postscrupt data into target format 
  GS_PARAMS="-q -sPAPERSIZE=$PAPER_SIZE -sDEVICE=$PRINTER_TYPE -sOutputFile=$TMPFILE -dNOPAUSE -dBATCH $1"
  echo "gs $GS_PARAMS" >>$LOG_FILE
  gs $GS_PARAMS >>$LOG_FILE 2>&1
  RESULT=$? 
  rm $INFILE
  
  # in case of errors
  if test "$RESULT" != "0"; then
    exit $?
  fi
  
  if test -f $TMPFILE; then
          echo "/usr/bin/lpr -l -d $PRINTER $TMPFILE" >>$LOG_FILE
          /usr/bin/lpr -l -d $PRINTER $TMPFILE >>$LOG_FILE 2>&1
          echo "rm $TMPFILE" >>$LOG_FILE
          rm $TMPFILE >>$LOG_FILE 2>&1
  fi
  exit $?
  

• change the variables PRINTER AND PRINTER_TYPE in the lp script as you need. You may consult the ghostscript documentations for supported printer types.
