hi ericP ... gcc 4.4 ears?
18:14:34 [ericP]
some
18:15:08 [ericP]

anyone near presbrey to see if my 53s turn-around exceeded his attention span?
18:38:43 [presbrey]
haha sorry right here
18:38:55 [presbrey]
I sent you some build output
18:40:24 [presbrey]
i have u always-on-top'd now ;)
18:44:37 [ericP]
now i can sell this channel to spammers
18:45:01 [presbrey]
its upset about FilterHolder
18:45:13 [presbrey]
lib/SPARQLfedParser/SPARQLfedParser.ypp:174: error: ISO C++ forbids declaration of ‘FilterHolder’ with no type
18:45:46 [danbri]
danbri has quit (Read error: 110 (Connection timed out))
18:46:10 [presbrey]
though it seems to be defined about up at 107
18:47:15 [presbrey]
does it have to say w3c_sw::FilterParser ?
18:47:32 [ericP]
if it's a question of uncertain inclusions (class Foo; vs. class Foo { ... };) i debug it by running the same compile line but with s/-c -o foo.o/-E/ and checking to see if the full defn
18:47:53 [ericP]
exactly the question i was asking myself
18:48:45 [ericP]
note "} // namespace w3c_sw" below it
18:48:51 [ericP]
seems like it's in a namespace
18:49:12 [ericP]
ahh, the invocation
18:49:41 [ericP]
everything else is in w3c_sw, so it seems like that error would have been tripped ages before
18:50:23 [presbrey]
yeah I tried being more explicit and it said "invalid use of ‘::’
18:50:23 [presbrey]
"
18:51:04 [ericP]
ahh, that's suspicious
18:52:00 [ericP]
try std::stack<int> instead
18:52:12 [ericP]
(just to exercise that same syntax)
18:53:30 [ericP]
is it easy to give me an account? (mailed you my ssh key)
18:53:47 [presbrey]
ok sure
18:54:51 [presbrey]
give me about 20 mins
18:55:55 [ericP]
sure
19:14:37 [presbrey]
the system im playing with swobjects on now is firewalled so I'm installing a fresh machine at MIT we can share
19:15:31 [presbrey]
its almost finished, 524/644 packages. maybe 5 more minutes
19:20:19 [ericP]
wow, ambitious
19:20:38 [presbrey]
hah well we'll want a sparul test server anyway
19:21:46 [presbrey]
its a virtual machine anyway
19:33:49 [presbrey]
ericP, try root@dig.xvm.mit.edu
19:34:29 [presbrey]
I'm running make in a `screen -xS swobjects` session there
19:35:12 [ericP]
got a password prompt
19:36:00 [presbrey]
.ssh/authorized_keys2, right?
19:36:17 [ericP]
debug1: Next authentication method: publickey
19:36:17 [ericP]

19:36:17 [ericP]
debug1: Authentications that can continue: publickey,gssapi-with-mic,password
19:36:29 [ericP]
try getting rid of "2"
19:36:59 [presbrey]
ok go for it
19:37:10 [ericP]
again
19:37:11 [presbrey]
nope huh

19:40:45 [presbrey]
works now, right?
19:42:10 [ericP]
worky
19:43:13 [presbrey]
i am building in /root/src/swobjects/
19:43:35 [presbrey]
dlib in /usr/local/include/dlib
19:43:42 [ericP]
tx
19:43:52 [ericP]
mind if i build in emacs?
19:43:57 [presbrey]
no go for it
19:44:17 [presbrey]
u might have to yum install
19:44:33 [ericP]
don't know yum
19:44:42 [ericP]
tx
19:46:36 [ericP]
pretty
19:46:37 [presbrey]
ooh nice make color coding
19:46:48 [presbrey]
screen is so cool
19:48:51 [presbrey]
yeah I'm not familiar with -E hmm
19:49:09 [ericP]
just dumps the preprocessor output
19:51:14 [ericP]
hmmm
19:51:43 [ericP]
can i table this for 20 mins while i get a piece of email out?
20:06:27 [ericP]
oof, that was one of the hardest emails i've written
20:08:43 [ericP]
oof, this is going to be difficult
20:08:58 [ericP]
i think 4.3 allowed you to have references to incomplete types
20:09:24 [ericP]
so i thought that was ok in C++ (and in fact, a good thing from a data/complexity hiding perspecitive)
20:13:02 [ericP]
re: errors like "error: #endif without #if", older bison's included a "#ifndef PARSER_HEADER_H" at the top
20:13:31 [ericP]
need to figure out when that behavoir changed and add some sensitivity to the code

presbrey, ears on for SPARUL?
20:39:11 [ericP]
do you expect to take advantage of: INSERT { GRAPH <g1> { <s1> <p1> <o1> } GRAPH <g2> { <s2> <p2> <o2> } } ?
21:01:01 [lkagal]
lkagal has quit ()
21:11:05 [presbrey]
ericP, no. single implied {graph <REQUEST_URI>}
21:11:21 [presbrey]
would be harder to stack mod_sparul with mod_authz_webid if you can change more than one graph with a single request
21:12:41 [presbrey]
feel free to use that server to debug that compiling issue at your convenience
21:12:56 [presbrey]
that issue is way beyond my scope
