tru64平台下cxx编译，出现ld:Unresolved:错误

caoronghai

我用的编译选项是
COPTIONS = -c -g -pt -pthread -D_XPG4_EXTENDED -Wall -DRWSTD_MULTI_THREAD -D_REENTRANT
CFLAGS   = $(COPTIONS) $(CINCDIRS) $(USEROPTS)
LDFLAGS  =  -o $(OUTPUT)
INCLUDEDIR = -I/usr/ccs/lib/cmplrs/cxx/V6.3-018/include/cxx/
LINK_WITH=  -lpthread -lm -lrt
# Compilation rules
#
CC = cxx
LD = cxx

警告和错误如下：
cxx -o processmonitor.o -c -g -pt -pthread -D_XPG4_EXTENDED -Wall -DRWSTD_MULTI_THREAD -D_REENTRANT -I/usr/ccs/lib/cmplp
cxx: Warning: ../snmp/snmp++/include/snmp_pp/uxsnmp.h, line 372: integer
          conversion resulted in truncation
                       const int fd = INVALID_SOCKET);

我分析应该是缺少联接的一些选项，如何解决阿？
