Compiler error

[rbuxton]

Hi all:

I am new in Asterisk and trying to port it to IXP425.
I got the following error:

/usr/local/bin/arm-linux-gcc -mbig-endian -g -o asterisk -Wl,-E io.o sched.o logger.o frame.o loader.o config.o channel.o translate.o file.o say.o pbx.o cli.o md5.o term.o ulaw.o alaw.o callerid.o fskmodem.o image.o app.o cdr.o tdd.o acl.o rtp.o manager.o asterisk.o ast_expr.o dsp.o chanvars.o indications.o autoservice.o db.o privacy.o astmm.o enum.o srv.o dns.o aescrypt.o aestab.o aeskey.o utils.o db1-ast/libdb1.a editline/libedit.a tinytcap/libtermcap.a stdtime/libtime.a -lpthread -lm -ldl

collect2: ld returned 1 exit status
make: *** [asterisk] Error 1

Someone told me it was due to old glibc (i am using 2.2.5). But I tried to upgrade to 2.3.3. It is same. Any comments?

Thanks
