Building GCC on Tru64 4.0f

["Gasperi Michael" <michael at gasperi dot priv dot at>]

Hi,

I'm having troubles compiling gcc (gcc-4.2-20070905) on Tru64 4.0f, I
think ld cannot find the required includes - sounds very simple but I
already made links to /usr/local/include so that it points to the right
headers - it looks like

-rw-r--r--   1 root     system      5749 Jul 13  2001 FlexLexer.h
drwxr-xr-x   6 root     system      8192 Aug 16  2002 g++-v3/
-rw-r--r--   1 root     system     82613 Oct  5 09:50 gmp.h
-rw-r--r--   1 root     system      4289 Dec 27  2002 iconv.h
-rw-r--r--   1 root     system      1385 Dec 27  2002 libcharset.h
-rw-r--r--   1 root     system     10477 Dec 27  2002 libintl.h
-rw-r--r--   1 root     system      6113 Oct  5 10:18 mpf2mpfr.h
-rw-r--r--   1 root     system     37375 Oct  5 10:18 mpfr.h
drwxr-xr-x   2 root     system      8192 Aug 16  2002 net/
-r--r--r--   1 root     system      3161 Jul 13  2001 pcap-namedb.h
-r--r--r--   1 root     system      4912 Jul 13  2001 pcap.h
drwxr-xr-x   7 root     system      8192 Aug 16  2002 php/
lrwxrwxrwx   1 root     system        20 Oct  8 09:39 sys@ ->
/usr/sys/include/sys/
-rw-r--r--   1 root     system      7810 May 15  2002 zconf.h
-rw-r--r--   1 root     system     40900 May 15  2002 zlib.h

-> it's the sys link which contains the required headers

I also tried to set the environment variables

LD_LIBRARY_PATH=/usr/sys/include
and
CFLAGS=/usr/sys/include

Thanks in advance
