# Net-SNMP 5.7.3
# ==============
# Prerequisites:
# procps
# Perl (unless --disable-embedded-perl and --without-perl-modules are passed)
# OpenSSL
# CUPS' lpstat (or lpr, lpr-ng, ...)
# Python (for the bindings in ./python/)
# MySQL (for MySQL trap logging)

# If you don't have OpenSSL installed in the usual source-installed place
# (/usr/local/ssl), like if you're using a distribution package that puts it
# under the /usr prefix, you can leave off the --with-openssl part.

# To build the Python bindings, either pass --with-python-modules to
# configure (requires the 'setuptools' module), or install them manually
# below

# If you are 64-bit and have a /usr/local/ssl/lib64, put the following at the
# beginning of the configure line:
# LDFLAGS=-L/usr/local/ssl/lib64

# Slackware's package uses --prefix=/usr --sysconfdir=/etc, etc.
# If you want to match paths with that

# Configure the build - 64-bit:
test $(uname -m) = 'x86_64' &&
./configure \
--with-openssl=/usr/local/ssl \
--libdir=/usr/local/lib64 \
--mandir=/usr/local/man \
--docdir=/usr/local/doc/net-snmp \
--with-defaults --with-python-modules --with-mysql

# Configure the build - anything else:
test $(uname -m) != 'x86_64' &&
./configure \
--with-openssl=/usr/local/ssl \
--mandir=/usr/local/man \
--docdir=/usr/local/doc/net-snmp \
--with-defaults --with-python-modules --with-mysql

# Build it

# If you did not use --with-python-modules, but want to install the Python
# bindings:
cd python
python build
su -c "python install"
cd ..

# Become root to remove old files and to install it

# If you're upgrading from ucd to net snmp, remove the old ucd files:
test -d /usr/local/include/ucd-snmp && rm -r /usr/local/include/ucd-snmp
test -d /var/ucd-snmp && rm -r /var/ucd-snmp
rm -f /usr/local/lib/libsnmp* /usr/local/lib/libucdagent* \
# And don't forget to wipe the ucd-snmp tarball and source too.

# If you're replacing a snmpd that was installed into the /usr prefix,
# with config files in /etc/snmp, back up that config file and zap the
# directory
test -f /etc/snmp/snmpd.conf &&
( mkdir -p -m 0700 ~/backup
   cp -a /etc/snmp/snmpd.conf ~/backup/snmpd.conf-$(date +%Y%m%d)
   rm -r /etc/snmp )

# You may also want to wipe out /usr/local/share/snmp to make sure
# everything in there is current.  I blow mine away (unless I customize
# files in there) and only back up my snmpd.conf:
test -f /usr/local/share/snmp/snmpd.conf &&
( mkdir -p -m 0700 ~/backup
   cp /usr/local/share/snmp/snmpd.conf ~/backup/ )
test -d /usr/local/share/snmp && rm -r /usr/local/share/snmp

# Before continuing, be aware that if you're upgrading net-snmp, any daemons
# that are running that are linked against the libnetsnmp* shared libraries
# may need to be rebuilt to be linked against the new version of the
# libraries.  For example, and older version's libraries may be named
# libnetsnmp*.so.9, but this one's will be libnetsnmp*.so.15
# Try 'lsof /usr/local/lib*/' to see what they are, if any.
# Either rebuild those apps, or skip the part below that removes old
# versions of the shared library files before running 'make install'.
# Some apps that can use libnetsnmp*.so are:
# Apache + PHP
# cyrus-imap
# freeradius
# and some non-daemon apps that may be running that can use it are:
# Wireshark

# Remove the Slackware package, if there is one

# If you still have yours, change the path from /usr to /usr/local.
# Here is one that is already fixed:
# Make sure something like /etc/rc.d/rc.M is going to start that script
# on boot-up or snmpd won't start.
# If you don't want to use that one, or if your Slackware doesn't
# have anything in /etc/rc.d/rc.M
## Add something like this to /etc/rc.d/rc.local to start it on boot-up
#if [ -x /usr/local/sbin/snmpd ]; then
#  echo "Starting net-snmp..."
