New Module

Adding a New module to the OO.o build

This process is somewhat complex, an example (adding cairo) is annotated here:

First create a your new module directory eg. libpixman

• makefile.mk - in your module directory. see following example what it should contain, it is important that your tarball is added to the libpixman/download/ directory.

  PRJ=.
  
  PRJNAME=libpixman
  TARGET=libpixman
  
  # --- Settings -----------------------------------------------------
  
  .INCLUDE :	settings.mk
  
  # --- Files --------------------------------------------------------
  
  .IF "$(GUI)"=="UNX"
  TARFILE_NAME=libpixman-0.1.5
  
  CONFIGURE_DIR=
  
  CONFIGURE_ACTION=./configure
  CONFIGURE_FLAGS=
  BUILD_DIR=$(CONFIGURE_DIR)
  BUILD_ACTION=$(GNUMAKE)
  
  OUT2LIB= \
  	$/src$/.libs$/libpixman.so.*
  
  OUT2INC= \
  	$/src$/pixman.h
  
  
  # --- Targets ------------------------------------------------------
  
  
  .INCLUDE :	set_ext.mk
  .INCLUDE :	target.mk
  .INCLUDE :	tg_ext.mk
  .ELSE  
  
  dummy:
  	@echo "Nothing to build for your platform"
  
  .ENDIF
  

• prj/build.lst - see following example and Hacking#prj.2Fbuild.lst detailed description]

  pm	libpixman		:	solenv NULL
  pm	libpixman			usr1	-	u	pm_mkout NULL
  pm	libpixman			nmake	-	u	pm_pixman NULL
  

• prj/d.lst - see following example and [detailed description ]

  mkdir: %_DEST%\inc%_EXT%\pixman
  ..\%__SRC%\inc\pixman.h %_DEST%\inc%_EXT%\pixman\pixman.h
  ..\%__SRC%\lib\libpixman.* %_DEST%\lib%_EXT%\libpixman.*
  
  linklib: libpixman.so.*.*.*
  linklib: libpixman.dylib.*.*.*
  

Extra bits for ooo-build

Of course, you'll need to turn all of the above into patch form for ooo-build; but ooo-build also has some infrastructure to help download the source you need easily; those need setting up:

• configure.in - usualy you want your module to be build conditionaly. inspire yourself by looking how mdb or cairo are handled.

  AC_ARG_ENABLE(cairo,
  [
    --enable-cairo          Enables cairo canvas backend.],
  ,)
  
  ...
  
  if test "$enable_cairo" != "no"; then
     CAIRO_ENABLED=TRUE
     LIBPIXMAN_VER=0.1.5
     GLITZ_VER=0.4.3
     CAIRO_VER=0.5.2
  else
     CAIRO_ENABLED=
     LIBPIXMAN_VER=
     GLITZ_VER=
     CAIRO_VER=
  fi
  AC_SUBST(CAIRO_ENABLED)
  AC_SUBST(LIBPIXMAN_VER)
  AC_SUBST(GLITZ_VER)
  AC_SUBST(CAIRO_VER)
  

• download.in - add your code to download package from network, best if you place the module tarball on ooo.ximian.com in /var/www/packages/SRC680/ directory.

  %SRC_URLS = (
      'binutils-.*'			 => 'http://go-ooo.org/packages/support',
  ...
      'libpixman-*'			 => 'http://go-ooo.org/packages/SRC680',
      'cairo-*'			         => 'http://go-ooo.org/packages/SRC680',
      'glitz-*'			         => 'http://go-ooo.org/packages/SRC680',
  
  ...
  
  if ('@CAIRO_ENABLED@' eq 'TRUE') {
      push @files, ( 'libpixman-@LIBPIXMAN_VER@.tar.gz' );
      push @files, ( 'cairo-@CAIRO_VER@.tar.gz' );
      push @files, ( 'glitz-@GLITZ_VER@.tar.gz' );
  }
  
  download_files (\@files, \%SRC_URLS, '@SRCDIR@');
  

• bin/setup.in - you can set environment variable by autoconf variable values here. the setup is sourced (as in shell terminology) in unpack, so you can use info from configure that way

  ...
  CAIRO_VER=@CAIRO_VER@
  CAIRO_ENABLED=@CAIRO_ENABLED@
  GLITZ_VER=@GLITZ_VER@
  ...
  

• bin/unpack - create a directory for your module in OOo tree, create another download directory for your tarball and copy it there

  ...
  if test "$CAIRO_ENABLED" == "TRUE"; then
      echo "Making symbolic links of libpixman, cairo and glitz at build location"
  
      mkdir -p $OOBUILDDIR/libpixman
      check_tarball $SRCDIR/libpixman-$LIBPIXMAN_VER.tar.gz
      mkdir -p $OOBUILDDIR/libpixman/download
      cp -a $SRCDIR/libpixman-${LIBPIXMAN_VER}.tar.gz $OOBUILDDIR/libpixman/download/
  
      mkdir -p $OOBUILDDIR/glitz
      check_tarball $SRCDIR/glitz-${GLITZ_VER}.tar.gz
      mkdir -p $OOBUILDDIR/glitz/download
      cp -a $SRCDIR/glitz-${GLITZ_VER}.tar.gz $OOBUILDDIR/glitz/download/
  
      mkdir -p $OOBUILDDIR/cairo
      check_tarball $SRCDIR/cairo-${CAIRO_VER}.tar.gz
      mkdir -p $OOBUILDDIR/cairo/download
      cp -a $SRCDIR/cairo-${CAIRO_VER}.tar.gz $OOBUILDDIR/cairo/download/
