11:13 tim-brown: ld: fatal: file mach_dep1.lo: unknown file type
11:13 tim-brown: ld: fatal: File processing errors. No output written to mach_dep.lo
11:14 tim-brown: I think "ld" in the command line refers to what would normally be gnu ld
11:14 tim-brown: when I configure with LD=/usr/sfw/bin/gld -- "ld" is still used in that command
11:15 tim-brown: ./racket/gc/mach_dep1.lo is:
11:15 tim-brown: # mach_dep1.lo - a libtool object file
11:15 tim-brown: # Generated by ltmain.sh - GNU libtool 1.5.24 (1.1220.2.455 2007/06/24 02:13:29)
11:15 tim-brown: 2
11:15 tim-brown: Sun's ld just gacks at it!
11:19 stamourv: Which configure flags did you use?
11:20 tim-brown: ./configure --prefix=/usr/local/racket-5.1.3 LD=/usr/sfw/bin/gld -m64 CC="/usr/sfw/bin/gcc -m64" CXX="/usr/sfw/bin/g++ -m64" --enable-shared
11:20 tim-brown: oops, there's quotes around the LD="...-m64", too
11:20 stamourv: Ok, so nothing that affects the gc.
11:20 stamourv: It seems like the BDW gc is what fails to build.
11:21 stamourv: Can you try adding the `--enable-sgc' flag?
11:21 stamourv: This will cause the Senora gc to be used instead of bdw.
11:21 tim-brown: I use BDW in other software... can I use my own build with racket?
11:22 tim-brown is running config right now
11:22 stamourv: I guess you could, but I don't see a flag for that. And I don't know if we use a straight BDW or a hacked-up one.
11:22 tim-brown: has always bugged me, that
11:22 stamourv: Besides, BDW (and I assume Senora) is only used to build the Racket with precise GC.
11:23 tim-brown: i'm embedding this racket; so i'll need a CGC
11:23 tim-brown: upgrading from plt-4.1.4
11:23 stamourv: Oh, I see.
11:24 stamourv: Then I guess Senora may be worth a shot.
11:24 tim-brown: the simple config string i gave is to just get *something* built
11:24 stamourv: But I would ask on the mailing list about using your own BDW.
11:25 tim-brown: occasionally, I'd like to mix my racket with swi-prolog -- so a shared GC is preferable to two different CGCs is preferable to tho builds of the same CGC
11:26 stamourv: Actually, I found something that may be helpful: `--enable-lt=<prog>'. This allows you to use your own libtool instead of the bundled one.
11:26 tim-brown: will look at that, although libtool is a script? i'm not so hot on the gnu-style toolchain
11:27 tim-brown: or is libtool something like "ld", "gld" "/.../path/ld"
11:27 tim-brown: ?
11:27 stamourv: As for Prolog, if you're not tied to swi specifically, there's Racklog, which is a prolog in Racket. No idea how mature/fast it is, though.
11:27 stamourv: Not sure (libtool).
11:27 tim-brown: will check out libtool
11:28 tim-brown: racklog (at last check) didn't have ! cuts
11:28 (quit) jsj: Ping timeout: 276 seconds
11:28 tim-brown: that was a couple of months ago
11:28 stamourv: I don't think it changed since.
11:28 tim-brown: (i think it was cuts, might have been bags or sets)
11:29 tim-brown: i also have prolog code I need to parse
11:30 stamourv: Found something: src/racket/gc/libtool.m4, line 162.
11:30 rapacity: racklog has cuts ?
11:30 stamourv: No, I was back to the ld issue.
11:30 rapacity: http://docs.racket-lang.org/racklog/cut.html
11:31 stamourv: Oops, replied to the wrong person.
11:31 stamourv: rapacity: Looks like it indeed.
11:32 tim-brown: (racklog) there was _something_ caused me to back away from it
11:32 rapacity: racklog also has bags and sets
11:32 rapacity: hehe
11:33 tim-brown: difference lists?
11:35 tim-brown: dunno. will revisit (it might just have been that it not satisfy my long-established loyalty to Prolog)
11:36 tim-brown: would be proper nice if I could use "Lisp" and "Prolog" in the same environment (for some value of Lisp and Prolog)
11:37 stamourv: I believe Mozart and Ciao are trying to do that. Haven't tried either.
11:38 tim-brown: stamourv: what did you find in libtool.m4?
11:38 tim-brown: oh l.162, not 62!
11:39 tim-brown: got further with sparc build
11:39 tim-brown: in /usr2/other/racket-5.1.3/src/racket/gc2

11:40 stamourv: Would `--enable-shared' fix that?
11:40 tim-brown: maybe
11:40 tim-brown: no... it's already on my config line
11:41 tim-brown: said library is in: ./racket/.libs/libracket-5.1.3.so
11:42 tim-brown: i.e. in ../.libs from where we attempt to run racketcgc
11:42 tim-brown: (although that is invoked with ../racketcgc)
11:42 stamourv: Looks like it's trying to build the precise gc.
11:43 stamourv: Since you don't need it, maybe `--enable-cgcdefault' would work.
11:43 tim-brown: there's a thought
11:43 tim-brown: !
11:44 tim-brown: will find out in a while... this machine predates clockwork
11:48 stamourv: Well, you did say sparc ;).
11:48 stamourv: Victorian or Edwardian?
11:51 tim-brown: afaict it makes no odds... this one's only got a single 500-tooth cog in it
11:53 stamourv: 500 teeth ought to be enough for anybody.
