[kaffe] Problem with gc_pgbits

[daniel at fh-konstanz.de]

Hello list!

I want to port kaffe-1.0.7 on arm7 with eCos as OS. I have taken the
kaffe-1.0.7, because this version was adapted for ecos from www.sinby.com.

I have built an eCos library; after this step, I have configured kaffe by
starting ‘configure’ with following option and environment variable settings:

whereis_ecosbase="/usr/local/Projekt/version_install"
whereis_arm_elf="`which arm-elf-gcc`/../../"
whereis_gcclib="`find ${whereis_arm_elf} -type d -name include | grep gcc-lib`"
whereis_kaffeh="/usr/local/kaffe-1.0.7_for_eCos-2.0/kaffe/kaffeh/kaffeh_for_1.0.7.exe"
export KAFFEH=${whereis_kaffeh}
export ECOS_ENV_DIR=${whereis_ecosbase}
export LDFLAGS="-nostartfiles -Ttarget.ld -nostdlib -L$ECOS_ENV_DIR/lib "
export OPTS="-O2 -Wall"
export CFLAGS="-mcpu=arm7tdmi -mbig-endian -malignment-traps -g $OPTS"
export CPPFLAGS="-I$ECOS_ENV_DIR/include -nostdinc -D__ECOS"
export COMMAND_PREFIX=arm-elf
export LD=$COMMAND_PREFIX-ld
export NM=$COMMAND_PREFIX-nm
export AR=$COMMAND_PREFIX-ar
export RANLIB=$COMMAND_PREFIX-ranlib
export CPP=$COMMAND_PREFIX-cpp
export OBJCOPY=$COMMAND_PREFIX-objcopy
export LD_LIBRARY_PATH=/usr/local/lib/

mv -f config.cache config.cache.old
make clean

sh configure --with-engine=intrp --with-includes=${whereis_gcclib}
--host=arm-ecos --build=i686-cygwin --with-staticlib --with-staticbinary
--with-staticvm

There is also a "config.frag" file in the directory "/config/arm/ecos/", which I
have modified with the following options:

After running the configure script, I wanted to build it with ‘make’. I get
following errors while running the makefile:

Can anybody analyse, why this error appears? I have checked the "gc-incremental"
file, but it includes the "mem-gc"-file, which include the necessary "gc_pgbits"
–Integer variable.
Thank you so much for answering!
