[ECOS] Re: [kaffe] Problem of porting kaffe to ecos on ARM 7 hardware target

[daniel at fh-konstanz.de]

Hello list!

i have taken the 'nostdinc' option into the CPPFLAGS again. 

PATH=$PATH:/usr/local/Diplomarbeit/gnuarm-3.4.3/arm-elf/bin:/usr/local/Diplomarbeit/gnuarm-3.4.3/bin:
export PATH
export
KAFFEH=/usr/local/Diplomarbeit/kaffe-1.1.5/kaffe-native/kaffe/kaffeh/kaffeh
export LDFLAGS="-nostartfiles -Ttarget.ld -nostdlib
-L/usr/local/Diplomarbeit/Project/Kaffe_V1/version1_install/lib"
export CFLAGS="-mcpu=arm7tdmi -mbig-endian -malignment-traps -Wall
-WI,--gc-sections -g -O2"
export
CPPFLAGS="-I/usr/local/Diplomarbeit/Project/Kaffe_V1/version1_install/include
-nostdinc -D__ECOS"
export 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

When i did 'configure
--with-includes="/usr/local/Diplomarbeit/gnuarm-3.4.3/arm-elf/include/
/usr/local/Diplomarbeit/gnuarm-3.4.3/lib/gcc/arm-elf/3.4.3/include"
--host=arm-ecos --build=i686-linux --without-classpath-gtk-awt
--enable-pure-java-math --with-gc=kaffe                                        
                                  '  in the 'kaffe-crossing' directory, i get
following errors after finishing the configure-script:

checking how to run the C preprocessor... arm-elf-cpp
configure: error: C preprocessor "arm-elf-cpp" fails sanity check
See `config.log' for more details.
configure: error: /bin/sh
'../../../../../kaffe/kaffevm/boehm-gc/boehm/configure' failed for
kaffe/kaffevm/boehm-gc/boehm


in 'config.log' i find some errors:

Whats the problem? Is the problem the arm-elf-gcc 3.4.3 compiler?

Thanks for answering
