how to test for linux base version? (googleearth)

[Juergen Lock-2]

I just got reminded to add a linux base version check to astro/google-earth
(It now needs recent linux libstdc++.so.6 with GLIBCXX_3.4.9 that only
is in f9 or f10, you can do
        objdump -T /compat/linux/usr/lib/libstdc++.so.6 |grep 'ABS.*GLIBCXX'
to check) - and was wondering how to best check for that in a port.
This is what I came up with so far:

Index: Makefile
===================================================================
RCS file: /home/pcvs/ports/astro/google-earth/Makefile,v
retrieving revision 1.35
diff -u -p -r1.35 Makefile
--- Makefile 24 Sep 2009 21:01:36 -0000 1.35

+.endif

 do-extract:

  @${CP} ${DISTDIR}/${DIST_SUBDIR}/${DISTFILES} ${WRKSRC}

 Anyone have a better idea? :)

 Thanx,

First of, I'd recommend leaving f9 alone (I'm going to deprecate all
linux base ports except fc4 and f10 soon).

I'm not sure if it's better but just an other idea:
-----
.if ${OSVERSION}<7000XX  /*** XX should be find out ***/
IGNORE FreeBSD>=7.X is needed with Linux emulation 2.6.x.
.elif ${OSVERSION}<800076 && \
        ! defined (OVERRIDE_LINUX_NONBASE_PORTS) ||
        ! (${OVERRIDE_LINUX_NONBASE_PORTS} == f10)
IGNORE= you need to use non-default linux ports (define OVERRIDE_LINUX_BASE_PORT=f10 and OVERRIDE_LINUX_NONBASE_PORTS=f10)
.endif
-----

This check is not strict either. The thing is that both BASE and NONBASE
variables should be defined and have f10 value for OSVERSION<800076.

I have an item at my TODO list to switch to using USE_LINUX=f10[+] or
similar but it's not the highest priority and ENOTIME now...

Ah Ok.  (Does f10 work well enough on 7.x yet?)

 In the meantime I found emulators/linux-systemsimcell does something
similar, and it uses ${OSVERSION}<700055 for the first check.  Does
that look alright?  (seems to be the last OSVERSION before 7.0-R from
looking at
        http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/book.html#FREEBSD-VERSIONS
)

 Heh yeah I guess that'd be useful here...

 Anyway, thanx, :)

It works pretty well with 7.2. I have heard that it might not with 7.1,
but I don't have any 7.1 systems, so that is hear-say. My 7.2 system
does Flash and Skype fine. I think it might do RealPlayer, but I'm not
completely sure on that. (It works on 8.0, though.)

Well, there is no choice anyway. We do have fc4 and f10 infractructure
ports. I think it's wise to use apropriate base ports. I don't think
there is any difference between f9 and f10 linux base ports.

If someone shows a difference (i.e. possibility to use f9 but not
f10 linux base port under 7.x I may change my mind).

We discussed those checks with the maintainer and his checks were good
(for his software). I can't say more than that, sorry.

Oh I was more thinking of f8 since we have nonbase ports for that too...

 Ok.  Maybe I should just commit it like that, I guess it's kinda
unlikely someone who's running a FreeBSD _desktop_ still uses something
as old as 7.0 anyway.

Hm, but it were you who said that only f9 and f10 base ports had
libstdc++.so.6 with apropriate symbols. ;-)

About f8 ports. Almost all current linux ports play well with f10
ports at 7.2, 8.0 and 9-CURRENT. Only one exception I'm aware is
acroread9 (a linux syscall should be implemented). If those ports
(f8) are usefull for 7.0 and 7.1 (6.x doesn't have apropriate
kernel sources) then they should stay until 7.0 and 7.1 are EOLed.

Oh yeah, that comment was meant more in general, not for this
specific port.
