15:52.09caen23brlcad: nice, i didn't know about that website :D
15:52.38brlcadit's the old koders.com site, but they bought them out / replaced them
15:53.32caen23bookmarked it, thanks
15:54.53brlcadof course a good ol' google search for "filetype:c hostname" along with other keywords can help, but be careful to not just pull code you find (plagerism and licensing concerns of course) but to just use it to learn
15:56.22caen23hmm… can i not use gethostname in unistd.h? do i have to rewrite that from scratch?
15:58.24brlcadyou can use it if it's available ... but it may not be depending on compilation settings
15:58.36brlcadlooks like it's posix 2001
15:59.04brlcadthe way to test is to add the function to the top-level CMakeLists.txt file and then wrap the usage in #ifdef HAVE_GETHOSTNAME
16:02.05brlcadsrc/libbu/progname.c and src/libbu/fchmod.c are other examples where we do this
16:02.25caen23what i'm currently doing is, if i'm on windows, i include winsock2.h. otherwise, unistd.h. works on mac, and i'm currently testing on deb. i'll then test on windows. i'm guessing it's older operating systems that are not posix 2001 and should be tested on?
16:03.16brlcadsee if what you need is in bin.h (networking) or bio.h (i/o)
16:03.25brlcadthose can be included without ifdef
16:04.21brlcadanything that's not part of c89 should usually be tested for, even some c99 constructs
16:04.29brlcadposix functions often fall in that boat
16:05.06caen23hmm… bio seems to include winsock2, and bin includes unistd :-?

16:06.03brlcadsounds like you have that reversed
16:07.05caen23yes, i do. but i'm thinking of including both bin and bio instead of what i'm currently doing (checking if i'm on win or not)

16:08.01brlcadso gethostname may be safe to use outright
16:08.05brlcadit's POSIX.1
16:08.10brlcadwhich started in c89
16:09.32caen23i also thought of seeing how python does it, if they use those headers or not
16:10.23brlcadif it works on windows, mac, bsd, and linux, that should be good enough to avoid a cmake function test
16:11.27brlcadwindows would have been the tricky risky one
16:11.49caen23i can test on windows, mac and linux, but i know that os x is based on a flavour of bsd, so doesn't it count as working on bsd? :D

23:04.26javamonnSo, can anyone help me work out an issue with subversion? I can't get it to pick up the changes I made to the checked out project. I think this is because I used a script to overwrite the files, and I guess it doesnt show that in the history. Is there a way I can get diff to look at all files, regardless of whether it shows they've been edited?
23:05.18javamonnIt's interesting because as soon as I go in and add a space to a file I edited with the script, it will show up on the diff with the appropiate edit.
23:06.38javamonnIt just wont pick up those edits made by the script for some reason, I guess since it doesn't show that the file has been edited.

23:43.04``Erik'svn diff' at the root should show all the changes, regardless of what program made them
23:43.19``Erikif the script creates new files, you'll need to do an 'svn add' to them
23:47.03javamonnDo I just navigate to the root and type svn add with the path? I mean they have the same name as the old version, but the way I wrote the script it would delete the file, then rewrite it with the appropiate changes.
23:47.43javamonnBut I checked out a fresh version, and it won't pick up the changes if I run a simple perl find and replace script, so I dont know whats going on
