hello, [it's very long,but i just want to ask questions more detaied,thanks for reading
on!]
i have been working on porting kaffe 1.1.4 to an xscale pxa255 linux board for
about one month.first i tried to use --with-awt=X,the cross compile process really
produced out an ARM version of kaffe,and with libawt.so(somthing like that).but at last i give up ,because i foud that my target board doesn't surport Xlibs. then i turned to use
--with-awt=qt,but unfortunately,i haven't get the cross process going well. here is it,hope someone be kind enough to help me out,thanks!
There is apparently a nasty problem with kaffe on xscale: the assembler code in config/arm directory uses some instructions for doubles and floats that aren't available on xscale, afaik.
step 2:
when enter into kaffe-1.1.4,use
CFLAGS="-D__XSCALE__" NM=arm-linux-nm AR=arm-linux-ar CC=arm-linux-gcc
./configure --with-awt=qt --disable-debug --enable-pxa --host=arm-linux --enable-pure-java-math KAFFEH=/usr/local/kaffe/bin/kaffeh
--with-rt-jar=/usr/local/kaffe/jre/lib/rt.jar --with-threads=unix-jthreads
--prefix=/usr/local/java --with-staticlib --with-staticvm --with-staticbin
--enable-static=yes
see,the options i used are too long,they are collected from the mailing archeve .but it still can't work .when i use make,error turned on.

Ah, okay. See http://www.kaffe.org/doc/kaffe/FAQ.cross-compiling . You need to have kaffe build and installed on the build platform, in order to use the local kaffeh.
quoting from the document:
"It does not work! ================= The way how to supply options to configure is roughly ok, but it is not enough. Because, include files needed to compile some library files are generated automatically while build, and 'jar' file is also generated while build. These files need runnable (on build computer) 'kaffeh' and 'kaffe' to generate.
To do that, you first have to make and install 'native' kaffe, and totally you may have three directories. In this document I use 'kaffe-1.1.0' where you store the source code, 'kaffe-native' where you make native kaffe, and 'kaffe-m68k-linux' where you make cross compiled kaffe.
Then, you have
. --- kaffe-1.1.0
+- kaffe-native
+- kaffe-m68k-linux
and, you first visit 'kaffe-native' and do '../kaffe-1.1.0/configure' and
'make; make install' first. Then you copy generated 'rt.jar' in somewhere
by
cp libraries/javalib/rt.jar /tmp/rt.jarAnd then, you can
CC=m68k-linux-gcc NM=m68k-linux-nm AR=m68k-linux-ar \
../kaffe-1.1.0/configure --host=m68k-linux --build=i686-linux \
--with-rt-jar=/tmp/rt.jar
"Of course, this raises the question whether we should not simply check in the header files into CVS to make it easier to (cross-)compile kaffe since that seems to be a regular stubling block.
I am really drunken mad for that,because i have tried many many times,with different options,and i really need it. i saw some body see CVS kaffe is better now ,but unfortunately,i can't access to CVS kaffe[sorry i don't know how to access,i tried cvs -d :pserver:[EMAIL PROTECTED]:/cvs/kaffe login ,but always timeout.and i can't download anything from ViewCVS / CVSWeb---you see now ,i am a really newbie to linux world,about 2 months.]
I'll put up a snapshot of CVS tomorrow, and send you a link. I'm just running late for a bis right now :(
i hope this helps a little,
cheers, dalibor topic
