18:30 samth: eli: what do you think is wrong w/ HOST_RACKET_BUILD_ROOT?
18:30 samth: something like that is needed for cross-compiling w/ 3m
18:33 eli: samth: I don't know which part is needed, or what you mean by "cross-compiling w/ 3m", but using the current directory is asking for trouble, and another issue is that (IIRC) paths are all relative to the source makefile.
18:33 samth: eli: he's cross-compiling racket
18:33 samth: but the target racket can't run on the host machine
18:33 samth: so there needs to be some version of racket to use for xform
18:33 eli: In short, this looks like something that would break if configure is used inside or outside the build tree.
18:34 samth: normally, racket uses the cgc version of racket that it just built to bootstrap
18:34 eli: That's cross-compiling period (I don't see 3m-specificeness here), but what I said still makes it broken regardless.
18:34 samth: but if the C compiler is compiling to another architecture, then that won't work
18:35 samth: the complication is only needed for 3m, b/c racket isn't part of the build process for cgc
18:35 samth: the current makefiles are all doing stuff relative to the current directory
18:37 eli: I have no idea how that's relevant.  If stuff in the makefiles is not relative to the current directory, then things are broken.
18:37 eli: Referring to something outside of the current build directory should be done by a new environment variable that points to that outside place.
18:37 (quit) mithos28: Quit: mithos28
18:37 eli: "Complication" is also an odd word for something that looks like it's broken.
18:37 (quit) lucian_: Remote host closed the connection
18:39 samth: that's exactly what that variable is doing -- pointing to someplace that might be outside the current directory
18:39 samth: but might also be in the current directory
18:40 eli: That sounds even more straightforwardly wrong.

18:42 eli: Yes, and you don't understand what I'm suggesting.

18:44 (join) mithos28
18:44 offby1: I bet there is
18:44 offby1: I'd be interested to hear how
18:44 samth: sheikra: see `read-syntax'
18:45 offby1: sheikra: and see http://planet.racket-lang.org/package-source/dyoo/bf.plt/1/4/planet-docs/manual/index.html for a nicely-written example of how to use it
18:45 rudybot: http://tinyurl.com/63997l7
18:45 offby1: (among some other things)
18:45 sheikra: samth: thanks!
18:46 samth: sheikra: then use `syntax-line', `syntax-column', etc
18:47 samth: eli: so the host version might be either the just-built cgc version, which is in the source tree
18:47 samth: or some other version, which would be outside the source tree
18:49 sheikra: samth: great
18:50 eli: samth: No, the just-built cgc version is *not* in the source tree.
18:50 samth: right, sorry, it's in the build tree
18:51 samth: which is also where the makefile is
18:51 sheikra: Do I open a file with open-input-file first then use read-syntax?
18:51 samth: sheikra: yes
18:54 sheikra: This is what I did ... (define f1 (open-input-file "t1.ss")) (define s1 (read-syntax f1)) ...

18:58 sheikra: I don't want the number of lines in the file. I want a list of sexps, with their line, col, start, end index information
18:58 eli: samth: Yes, it's in the build tree, which is why adding a "CURDIR" variable is bogus.  Instead, it could run racketcgc as usual or, when some environment variable is specified, from there.
18:58 (join) dnolen
18:59 jonrafkind: sheikra, what is a line?
18:59 samth: sheikra: `port-count-lines!' enables line/column/character information for that port
18:59 samth: eli: that's exactly what it's doing
19:00 eli: sheikra: You're missing an argument -- see the docs.  (You need something like (read-syntax 'foo <input-port>))
19:00 eli: samth: No, that's not what it's doing -- it makes it always use $CURDIR.
19:00 sheikra: eli: oh, but what should 'foo be?
19:01 jonrafkind: actually he wanted (with-input-from-file "t1.ss" (lambda () (read-syntax)))
19:01 jonrafkind: oh nevermind, you're right
19:02 samth: eli: isn't that CURDIR at build time -- therefore, in the build tree?
19:02 eli: sheikra: 'foo should be the name of the port -- the common convention would be (object-name <input-port>)
19:03 eli: samth: That's exactly why I started with "questionable" -- if that's what CURDIR is, then it is not needed; the fact that it was makes it suspicious and very likely broken.
19:03 sheikra: eli: ah, ...
19:04 samth: as in, instead of using CURDIR, you'd use "" ?
19:04 sheikra: eli: I just have a line "(lambda (x) x)" in the file t1.ss, and I want a sexp returned from the parser, with all the location information for (lambda (x) x), lambda, (x), and x ...

19:07 riddochc: Heya. I'm having problems building racket-textual-5.1.1 on solaris, with --disable-libffi.
19:08 riddochc: In particular, this is what I get from part of the main configure script, when it calls the configure script in foreign/libffi:
19:08 riddochc: === configuring in foreign/libffi (/ma/home/criddoch/racket-textual-5.1.1/src/build/foreign/libffi)
19:08 riddochc: configure: running /bin/bash ../../../foreign/libffi/configure '--prefix=/ma/home/criddoch/'  '--disable-gracket' '--enable-usersetup' '--disable-libffi' --cache-file=/dev/null --srcdir=../../../foreign/libffi
19:08 riddochc: configure: WARNING: unrecognized options: --disable-gracket, --enable-usersetup, --disable-libffi
19:11 riddochc: So, foreign.o gets built, but it fails when trying to link - likely, because there really is no libffi to link to.
19:23 samth: riddochc: those warnings aren't a problem
19:23 samth: but it ought to not try to link that at all
19:23 riddochc: Maybe not, but it still tries to link, and fails.
19:24 samth: riddochc: you need to use --disable-foreign
19:24 samth: --disable-libffi is about whether it uses the system or bundled version of libffi
19:25 riddochc: Oh. I was using disable-libffi because there isn't an installed libffi... I suppose I should have just let it figure it out for itself.

19:34 riddochc: Good question.  Perhaps it couldn't find ar.
19:34 riddochc: This is a pretty wonky solaris setup.
19:34 riddochc: Just a guess.
19:36 riddochc: Yeah, ar isn't found.  And it looks like it can't find a header necessary for file locking, in racket/src/port.c.  implicit definition of flock, FLOCK_EX undeclared, etc.
19:36 riddochc: Okay, looks like I have bigger problems.  Thanks for the help. ;)
19:36 riddochc: Without ar, I suspect I'm out of luck on this anyway.
19:37 jonrafkind: well yea but why dont you have ar
19:37 jonrafkind: isnt that pretty standard?
19:38 riddochc: Heck if I know.  Solaris.  Heh.
19:40 riddochc: I live in linux-land most of the time.  In fact, the entire reason I was trying to build racket is because I can do something approaching what I'd otherwise do with shell scripts, but the differences between solaris and gnu tools... well.
19:41 riddochc: Sed doesn't have -i.  I don't know how sed is usable at all, without that.  Just as an example.
19:41 jonrafkind: yes the bsd toolset is an abomination
19:41 jonrafkind: but you can just install the gnu tools
19:41 bremner: solaris is not NSF
19:41 bremner: err bsd
19:41 riddochc: BSD is another beast altogether, I thought.  Another branch of the unix history.
19:42 bremner: sunos was bsd
19:42 riddochc: And yes, I could just install the gnu tools, if I could build them, which without 'ar' or sysadmin privileges seems extremely unlikely.
19:43 riddochc: Maybe ar is just in an sbin directory somewhere.  In any case, this obviously isn't a racket problem.
19:43 jonrafkind: i thought solaris, osx, and freebsd all shared the same basic tools
19:44 riddochc: It's... complicated, jonrafkind. But, I do want to say, cheers for racket - The 'fold-files' function alone makes racket a nice shell-script replacement, or sysadmin tool.
19:45 jonrafkind: does it descend into sub-directories?
19:46 (quit) sheikra: Quit: Leaving
19:46 riddochc: Yes, it does.
19:47 riddochc: And it's a proper fold, too, so I can accumulate properties of any group of files/directories I need.
19:48 lisppaste: riddochc pasted "demo of fold-files" at http://paste.lisp.org/display/122612
19:50 riddochc: First command-line-arg is turned into a regex, second is a path.  This finds the total file size of all files matching that regex in that path, and subdirectories.
19:50 riddochc: There may be a better way to do this, but this was the first thing I came across that looked like it would do what I wanted.
19:52 jonrafkind: yea looks good
19:52 riddochc: It's likely that bash or zsh has some clever way of doing the same, but this was pretty easy to do.
19:52 jonrafkind: now i have to see if python's os.walk can do it :p
