I tripped over this while trying to build a local release ..

imb@toshi:/home/imb> pkg --version
1.17.1

Is this expected?


Why $$ instead of $? $ isn't expanded in '' expressions, so doubling isn't
necessary
unlike in make... With single quotes it works for me:

% pkg --version | awk -F. '{print $1 * 10000 + $2 * 100 + $3}'
11603
% pkg --version
1.16.3

In awk $$n is $($n), so $$ in this context would evaluate $1 to 1 and then
$1 to be 1. And then $2 to be 16
and then $17 to be 0 and then $3 to be 1 and then $1 to be 1 which leads to
10001.

What prompted the question was my (obviously poor) attempt to debug and resolve this failure when attempting to build a release for i386 on an amd64 ..

make -C /usr/src/release  obj
make -C /usr/src/release  ftp cdrom memstick.img mini-memstick.img
mkdir -p dist
cd /usr/src/release/.. && make TARGET_ARCH=i386 TARGET=i386 distributeworld DISTDIR=/usr/obj/usr/src/i386.i386/release/dist make[3]: "/usr/obj/usr/src/i386.i386/toolchain-metadata.mk" line 1: Using cached toolchain metadata from build at vm01.auburn.protected-networks.net on Wed Jul 28 18:01:01 UTC 2021
