[kaffe] Problem to generate kaffe binary with ecos on arm7 processor

[daniel at fh-konstanz.de]

Hello list!

I want to port kaffe-1.1.5 on an embedded os called "eCos". As hardware platform
i use an arm 7 processor. Before configuring the kaffe-1.1.5 source code, i have
built an ecos library with the "arm-elf-gcc" cross compiler version 3.3.
The next step is to make and install 'native' kaffe. I have created three
directories:
'kaffe-1.1.5, where i stored the source code, 'kaffe-native' where i made native
kaffe, and 'kaffe-crossing', where i made cross compiled kaffe.

I changed the directory into 'kaffe-native' and did '../kaffe-1.1.5/configure'
and 'make; make install'. 

The next step was to create a cross compiled binary. First, i have set my
environment for cross-compiling:

KAFFEH=/usr/local/Diplomarbeit/kaffe-1.1.5/kaffe-native/kaffe/kaffeh/kaffeh

LDFLAGS="-nostartfiles -Ttarget.ld -nostdlib
-L/usr/local/Diplomarbeit/Project/Kaffe_V1/version1_install/lib"

CFLAGS="-mcpu=arm7tdmi -mbig-endian -malignment-traps -Wall -WI,--gc-sections -g
-O2"

CPPFLAGS="-I/usr/local/Diplomarbeit/Project/Kaffe_V1/version1_install/include
-D__ECOS"

CC=arm-elf-gcc
export LD=arm-elf-ld
export NM=arm-elf-nm
export AR=arm-elf-ar
export RANLIB=arm-elf-ranlib
export CPP=arm-elf-cpp
export OBJCOPY=arm-elf-objcopy


After setting the environment, i have copied the directory
'kaffe-1.1.5/kaffe/kaffevm/systems/unix-pthreads' in the same directory and
named it with 'ecos-native' without modifiing the files in it.

I have adapted the 'config.sub' files in
'kaffe-1.1.5/kaffe/kaffevm/boehm-gc/boehm' and in 'kaffe-1.1.5/libltdl' by
adding 'ecos' as os machine and the 'configure' file in 'kaffe-1.1.5'. 

Then i changed into the 'kaffe-crossing' directory and did:

'../kaffe-1.1.5/configure --host=arm-ecos --build=i686-linux
--without-classpath-gtk-awt --enable-pure-java-math

The 'configure' script wis ok, but when i try to do 'gmake' after configuring, i
get some errors like this:

Can anybody help me. Do i have to add an additional configure option?
Thanks for helping!
