[kaffe] Kaffe on YOPY, arm-linux PDA

[Sebastian Mancke]

Hello.

I have successfully cross compiled Kaffe 1.1.0=20
for my arm-linux based PDA: YOPY, from GMate.
(Thanks for the FAQ.cross-compiling)

It seems to work fine.

For correct fonts, i had to update the libX11.so.6 on the YOPY.
(http://familiar.handhelds.org/familiar/releases/v0.5.2/packages/armv4l/x=
libs_4.1-5_arm.ipk)

I will provide the binary package at.:
http://www.mancke-software.de/yopy/java.html

The YOPY has 207 MHz and 64 MB SD Ram
(The ram is used for both: filesystem and working memory.)
Is it possible to optimize Kaffe for such small systems?
For example by compile options for heap sizes=20
or making the binary size smaller?


Sebastian.

During the build procecc I ran in two small problems:

1. I had to remove the line 431 in=20
kaffe-1.1.0/libraries/clib/net/InetAddressImpl.c

2. It inherently uses /usr/lib/libjpeg.so instead of=20
/usr/arm-linux/lib/libjpeg.so
I also tryed to set the lib dirs by the following options:
	LDFLAGS=3D-L/usr/arm-linux/lib/=20
	--with-libraries=3D/usr/arm-linux/lib/
	--with-awtlibpath=3D/usr/arm-linux/lib/
Theese had no affects.
My dirty fix was replacing the PC lib with an link to the arm lib.
