Port of jules 0.0.1 to Icedtea7, and first impression when running on ARM.

[Xerxes Ranby]

Hi

I had some fun trying to get Jules working with the current Icedtea7 trunk.
http://linuxhippy.blogspot.com/2009/11/jules-cairo-binding-001-release.html

Getting jules to build was quite easy. I had to configure icedtea7 with
--disable-xrender so that  it skips to patch openjdk with the xrender
patches currently bundled with icedtea and then manually patched the
openjdk/jdk source dir with the webrev patch from the jules-0.0.1
release, I was delighted to see that the jules patch applied cleanly.
The rest of the build went smooth.

In order to get Jules 0.0.1 integrated into icedtea7 the file paths in 
the jules  webrew patch needs a slight adjust to be openjdk relative 
instead of jdk  relative so the patch can be applied directly on the 
openjdk tree like  other icedtea patches and the old xrender patches.

I hit some issues when running openjdk with the jules renderer on my ARM 
PC-Z1, see the attached  images, basically all menus are empty of 
typefaces and no vector graphics are dawn at all.  the only things that 
seems to be drawn ok where gray panels and some images. Images gets 
funny though when the frame are redrawn after being overlapped by a 
window, see the green glitches in the jules-xrender-arm-redraw-glitch.png .

I beleve these issues are related to the cairo compilation when making
libjules.so, during the compilation these messages got displayed that
seems relevant:
cairo (version 1.9.2 [snapshot]) will be compiled with:

The following surface backends:
   Image:         yes (always builtin)
   Xlib:          no (disabled, use --enable-xlib to enable)
   Xlib Xrender:  no (disabled, use --enable-xlib-xrender to enable)
   Quartz:        no (requires CoreGraphics framework)
   Quartz-image:  no (disabled, use --enable-quartz-image to enable)
   XCB:           no (disabled, use --enable-xcb to enable)
   Win32:         no (requires a Win32 platform)
   OS2:           no (disabled, use --enable-os2 to enable)
   CairoScript:   no (disabled, use --enable-script to enable)
   PostScript:    no (disabled, use --enable-ps to enable)
   PDF:           no (disabled, use --enable-pdf to enable)
   SVG:           no (disabled, use --enable-svg to enable)
   glitz:         no (disabled, use --enable-glitz to enable)
   BeOS:          no (disabled, use --enable-beos to enable)
   DirectFB:      no (disabled, use --enable-directfb to enable)

The following font backends:
   User:          yes (always builtin)
   FreeType:      no (disabled, use --enable-ft to enable)
   Fontconfig:    no (disabled, use --enable-fc to enable)
   Win32:         no (requires a Win32 platform)
   Quartz:        no (requires CoreGraphics framework)

The following functions:
   PNG functions: no (disabled, use --enable-png to enable)

And the following internal features:
   gtk-doc:       no
   gcov support:  no
   test surfaces: no (disabled, use --enable-test-surfaces to enable)
   ps testing:    no
   pdf testing:   no
   svg testing:   no


+++ It is strictly recommended that you do NOT disable the PNG functions

+++ It is strictly recommended that you do NOT disable the PostScript
surface
+++ backend feature.

+++ It is strictly recommended that you do NOT disable the PDF surface
+++ backend feature.

+++ It is strictly recommended that you do NOT disable the SVG surface
+++ backend feature.

*** It is strictly recommended that you enable the native surface backend
*** feature for your platform.

*** It is strictly recommended that you enable the native font backend
*** feature for your platform.

I also noticed that libjules.so can be compiled in combination with 
pixman 0.13 instead of 0.15 by simply lower the requirements during 
configure.

Cheers, and have a great day!
