[kaffe] kaffe & diet libc

[Martin Pohlack]

Hi,

I'm currently investigating which libc to port do DROPS in order to port 
kaffe to it. My first candidate is "diet libc".

My first step, was to configure the following way:

CC="diet gcc -nostdinc -D_BSD_SOURCE" ./configure --disable-nls

The next "make all" fails in replace/ with the following error:

In file included from ifaddrs_linux.c:37,
                  from getifaddrs.c:30:
/mnt/erwin/mp26/dietlibc/include/errno.h:539: warning: `__set_errno' 
redefined
getifaddrs.c:23: warning: this is the location of the previous definition
In file included from getifaddrs.c:30:

In file included from getifaddrs.c:30:
ifaddrs_linux.c:47: net/ethernet.h: No such file or directory
make: *** [getifaddrs.lo] Error 1



I circumvent this by manually issuing the last libtool call with "-Ulinux":

/bin/sh ../libtool --mode=compile diet gcc -nostdinc -D_BSD_SOURCE 
-Ulinux -DHAVE_CONFIG_H -I. -I. -I../config -I../include  -I.. -I.. 
-DKVER='"1.1.x-cvs"' -I/home/mp26/erwin/kaffe/./kaffe/kaffevm 
-I/home/mp26/erwin/kaffe/./kaffe/kaffevm/systems/unix-jthreads 
-I../config -I../include  -DKAFFE_VMDEBUG  -g -O2 -Wall 
-Wstrict-prototypes -c -o getifaddrs.lo `test -f 'getifaddrs.c' || echo 
'./'`getifaddrs.c


The again "make all" in kaffe/ :

Any ideas? Or has anyone succesfully compiled kaffe with "diet libc"?
