The main build guy (who has been helping me) is on vacation this week, so I had
to try to figure out this myself.
It seems one of the most important aspects of the "configure" command is the
"--target" option ....... and I was not using this option previously. Anyway,
I asked around and it seems the CPU-MANUFACTURER-OS we are using is
"mipsel-uclibc-linux" so I added the "--target" option to my "./configure"
command as follows:
./configure \
--prefix=$(BUILDROOT)/usr/local \
--srcdir=$(BUILDROOT)/netsnmp \
--with-default-snmp-version="3" \
--with-sys-contact="contact" \
--with-sys-location="location" \
--with-logfile="$(BUILDROOT)/netsnmp/var/log/snmpd.log" \
--with-persistent-directory="$(BUILDROOT)/netsnmp/var/net-snmp" \
--disable-embedded-perl \
--without-perl-modules \
--host=localhost \
--target=mipsel-uclibc-linux \
--with-cc=$(CC) \
--with-linkcc=$(CC) \
--with-cflags="-x c" \
--with-ldflags="-x none" \
--with-endianness=little;
** Note: I am not sure if the "--host=localhost" option setting is correct, but
this was set our main build guy over here so I am assuming it is correct.
Anyway, after running the "./configure" command, there were still similiar
compiler errors being produced (shown below). Is there reason to believe my
cross-compilation setup might still be incorrect?
Here shows the "snmpd.c" module being compiled:
/bin/sh ../libtool --mode=compile mipsel-uclibc-g++ -I../include

I looked in the email archives and found this reply from you on 6/28:
Subject: Does a patch exist --> "mibgroup/mibII/at.c:727: error
The "-Ulocalhost -Dlocalhost=localhost" suspiciously looks like your
(cross-)compilation setup didn't specify a correct target. See
http://www.freesnmp.com/net-snmp/faqs/#cross for some more information.
Again, this is in no way specific to Net-SNMP.
Seems like your reply was during the same day Magnus' replied as well (which I
did not receive either). I probably did not receive any of those postings
that day due to some problem I guess ..... not sure what could have happened.
None of these emails were in my "delete" queue either, so I know I did not
accidently delete them.
I understand how you would intepret me as "not trying", but please understand I
never received this email for some unknown reason. As a result, I can not try
recommendations I never received. I guess I will always need to check the
email archives first before posting.
Anyway, I have now obviously have found your email and will get together with
our build people and try to look into your recommendation. I do appreciate
your help. It is not my intent to be bothersome to others on this forum.
Thanks.

The last email response I received from you was the following:
"This is likely a problem with your cross-compilation setup. I'd suggest
to take this up with your build team and/or the cross-compilation
toolchain people."
I am not familiar with what cross-compilation stuff you were referring to, but
I have been working for two days with our build person to try to resolve all
compiler issues. I have tried everything people here have recommended (most
recently Magnus' recommendations). Have you posted new emails to the group?
If so, I have not received any. I will once again look in the email archives
to see if I have missed any responses (as I did not ever receive Magnus' email
response on how to solve the "error stray" errors until I looked into the
email archives).
Please believe me, I am trying all recommendations and do appreciate
everyone's help. I am trying to resolve this stuff by myself, and only ask
questions when I just can not figure out where to go next.

It still doesn't look as if you've even recognized (let alone tried) the
suggestions I've been giving you here twice. Similar things have
happened with suggestions from other people on this list. Why? May I
suggest you work on improving in this regard if you expect further help?
