Hello,
Some time back I posted a question regarding how to determine what
ports/packages would need to be installed on my machine when I install a
new (new to the local machine) port.
For example, if I do not presently have openoffice installed... what
will get installed when I 'make install clean' it? Note that I want the
differences between what is needed to build/run the port and what is
already present on the machine.
At the time no one responded with a clear way to do this... so I finally
had a few minutes to write a script to do it for me. I thought someone
else might find it useful... So I'm posting it here for comments and
thoughts (be gentle, I'm new to awk).
I find it useful, especially for laptops... which may have a small HDD
and little memory. I generally try to install the minimum necessary to
do my work.
#! /bin/sh
# Script to determine the differences between what is necessary for
# a port, and what is already present on the local machine.
make pretty-print-build-depends-list | \
awk '{
count = 0
pkgs = ""
for(i=5; i<=NF-2; i++) {
pkg = $i
if (index(pkg, "\"") == 1)
{pkg = substr(pkg, 2, length(pkg)-1)}
if (index(pkg, "\"") > 1)
{pkg = substr(pkg, 1, length(pkg)-1)}
if ( system("pkg_info -e " pkg) == 1) {
pkgs = pkgs " " pkg
count++
}
}
if ( count ) {
print "You need the following (build) perequisites:"
print pkgs
}
else {
print "All (build) prerequisites are present."
}
}'
make pretty-print-run-depends-list | \
awk '{
count = 0
pkgs = ""
for(i=5; i<=NF-2; i++) {
pkg = $i
if (index(pkg, "\"") == 1)
{pkg = substr(pkg, 2, length(pkg)-1)}
if (index(pkg, "\"") > 1)
{pkg = substr(pkg, 1, length(pkg)-1)}
if ( system("pkg_info -e " pkg) == 1) {
pkgs = pkgs " " pkg
count++
}
}
if ( count ) {
print "You need the following (run) perequisites:"
print pkgs
}
else {
print "All (run) prerequisites are present."
}
}'
