Port Postgres on the Acme system FOXBOARD

Hi !

For my project I would like to port the PostgreSQL on the Acme system FOXBOARD (http://www.acmesystems.it/?id=4).  I have to cross-compile the sources with the CRIS architecture (gcc-cris compiler already installed on my computer). I work with version 8.2.5 of Postgres. And it is impossible to find an example of cross-compilation.

I have tried to use the command ./configure with many arguments :

 ./configure --host=cris-axis-linux-gnu --prefix=/home/romain/postgresql_out/ CC="/usr/local/cris/bin/gcc-cris -mlinux" --without-readline --without-zlib

 But when I launch the command make it tells me :

/usr/local/cris/bin/gcc-cris -mlinux -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -fno-strict-aliasing -I../../src/include -D_GNU_SOURCE   -c -o localtime.o localtime.c
/usr/local/cris/bin/gcc-cris -mlinux -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -fno-strict-aliasing -I../../src/include -D_GNU_SOURCE   -c -o strftime.o strftime.c
/usr/local/cris/bin/gcc-cris -mlinux -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -fno-strict-aliasing -I../../src/include -D_GNU_SOURCE   -c -o pgtz.o pgtz.c
/usr/local/cris/cris-axis-linux-gnu/bin/ld -r -o SUBSYS.o localtime.o strftime.o pgtz.o

Do somebody have any information on how to do the cross-compilation and to solve my problem ?

Thanks a lot.
