[Mark]

I'm trying to compile 3.0.4 on solaris 8 and keep running into this error.. gcc version is 3.0

setenv CFLAGS "-Wall"
./configure --prefix=/opt/sw/samba/3.0.4 --with-acl-support --with-syslog 
make proto
make


and i get this error

Using FLAGS =  -Wall -I./popt -Iinclude -I/root/source/samba-3.0.4/source/include -I/root/source/samba-3.0.4/source/ubiqx -I/root/source/samba-3.0.4/source/smbwrapper  -I. -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/local/include -I/root/source/samba-3.0.4/source    
      LIBS = -lsec -lgen -lresolv -lsocket -lnsl -ldl -liconv
