I think this should rather go under "Hardware handling" like
smartmontools or hdparm.

It also uses iconv (to figure out how to print a degrees celsius sign,
gaah), so you need to add:

       select BR2_PACKAGE_LIBICONV if !BR2_ENABLE_LOCALE

And add it to HDDTEMP_DEPENDENCIES. A quick test shows that it forgets
to link with it, so it needs some help:

ifeq ($(BR2_PACKAGE_LIBICONV),y)
HDDTEMP_DEPENDENCIES += libiconv
HDDTEMP_CONF_ENV += LIBS="-liconv"
endif

It also needs a small patch to build without gettext as it
unconditionally calls:

  setlocale (LC_ALL, "");
  bindtextdomain (PACKAGE, LOCALEDIR);
  textdomain (PACKAGE);

Those needs to be inside #ifdef ENABLE_NLS conditionals.

And finally there's code in backtrace.c that breaks when building with
uClibc on i386 (as uClibc also defines __GLIBC__ for compatibility but
doesn't provide backtrace functionality by default):

#if defined(__i386__) && defined(__GLIBC__)

These patches should preferably be upstreamed, but as the latest (beta!)
release is 10 years old by now, the project seems pretty dead.

The savannah status is also listed as Orphaned/Unmaintained.

The source files contain the "(at your option) any later version"
wording, so this should be GPLv2+

Like Thomas mentioned, this is already taken care of in target-finalize.


The big question is how to handle hddtemp.db?

The tarball doesn't contain the file, so hddtemp doesn't do anything
sensible:

sudo ./target/usr/sbin/hddtemp /dev/sda
hddtemp: can't open /usr/share/misc/hddtemp.db: No such file or directory

The file is available on the upstream website, but it is not versioned -
So that is not suitable for Buildroot:

http://www.guzu.net/linux/hddtemp.db

Either we:

- Convince upstream to version this file (and preferably include it in
  the tarball) - But as the project seems dead this might be hard

- Apply the Debian patch which includes (an older version of?)
  hddtemp.db. Notice that Debian also patches various things in the
  code, so please check that the changes make sense in the context of
  Buildroot:
  http://http.debian.net/debian/pool/main/h/hddtemp/hddtemp_0.3-beta15-52.diff.gz

- We include hddtemp.db in package/hddtemp. It isn't really nice, but
  the file is relatively small (29K)

Given the missing hddtemp.db, how have you tested this package?
