And I was NOT refering to INRIA distributions particularly, but generally available packages including those from third parties. Above it is said ledit is writtin in camlp4, another package I've had trouble installing. I'm now using the CDK release of Ocaml. Perhaps that comes bundled with p4: root@pelican] ~/ledit/ledit-1.8>make ocamlc -pp "camlp4r pa_extend.cmo q_MLast.cmo" -I `camlp4 -where` -c pa_local.ml/bin/sh: camlp4: command not found sh: camlp4r: command not found Preprocessing error make: *** [pa_local.cmo] Error 2 No, it looks like it doesn't. So I build camlp4 (no problems). Now I can build ledit (although it isn't clear that I should run 'make install' to use it). I try ledit ocaml and I have line editing. So this time, I have no problems with either camlp4 or ledit. > Also for CamlImages, please report us your problems, we will help you > and fix the library for everybody. OK. I try again. The .configure summary is surprising: Language: ocaml version 3.01 Installed in: /usr/local/lib/ocaml/camlimages External libraries: bmp png jpeg tiff xpm ps Lablgtk: Not found No Lablgtk? Hmm. I have gtk. (My WM is Enlightenment :-) OK, try the make: ocamlc -I corelib -I ppm -I jpeg -I tiff -I bmp -I gif -I png -I xpm -I xvthumb -I ps -I graphics -I freetype -c corelib/camlimages.ml File "corelib/camlimages.ml", line 24, characters 0-3: Syntax error make: *** [corelib/camlimages.cmo] Error 2 Oops. Without even looking, the code is probably using pre 3.01 syntax. I'll check. Here's the file: (* Supported libraries *) let lib_gif = false let lib_png = true let lib_jpeg = true let lib_tiff = true let lib_freetype = let lib_ps = true (* External files *) let path_rgb_txt = "/usr/X11R6/lib/X11/rgb.txt" let path_gs = "/usr/bin/gs" (* They are written in ML, so always supported *) let lib_ppm = true let lib_bmp = true let lib_xvthumb = true (* Word size, used for the bitmap swapping memory management *) let word_size = 4 Well, the error isn't where the compiler says it is, but the file is small, and the bug is easy to spot: the line lib_freetype = should have 'false' as the value, not a blank. I'll edit it. OK, now it compiles. Try the test as indicated in the INSTALL notes: >root@pelican] ~/camlimages-1.02/test>make test ocamlc -custom -I ../corelib -I ../gif -I ../jpeg -I ../tiff -I ../bmp -I ../ppm -I ../png -I ../graphics -I ../freetype -I ../xpm -I ../xvthumb -I ../ps -cclib "-L../corelib -L../gif -L../jpeg -L../tiff -L../png -L../freetype -L../xpm" img.cma graphics.cma graphic_image.cma freetype.cma gif_img.cma jpeg_img.cma tiff_img.cma bmp_img.cma ppm_img.cma png_img.cma xvthumb_img.cma xpm_img.cma ps_img.cma -o test test.ml /tmp/cc5Dv2bQ.o(.data+0x3c4): undefined reference to `set_Instance_PixelSizes' /tmp/cc5Dv2bQ.o(.data+0x3e4): undefined reference to `get_Big_Glyph_Metrics' /tmp/cc5Dv2bQ.o(.data+0x3f8): undefined reference to `get_Outline_BBox' /tmp/cc5Dv2bQ.o(.data+0x3fc): undefined reference to `get_Face_Properties' /tmp/cc5Dv2bQ.o(.data+0x400): undefined reference to `get_Outline_Contents' collect2: ld returned 1 exit status Error while building custom runtime system make: *** [test] Error 2 Hmmm.

Sigh. I am now using Ocaml to produce software I want other people to use. I also happen to be using a literate programming tool written in Python. I am going to have to ask developers to a) download and install Python b) download and install interscript c) download and install Ocaml d) download and install any other third party packages I might be using e) download and install Felix f) download and install Boost (a public set of C++ libraries) Luckily, Felix is a 'pure Ocaml' program: it only includes a couple of minor hacks that might be platform dependent, so at present, I probably don't need anything under item (d). I provide python scripts to build Felix -- but they'll probably only work under Linux, and probably only on my box. I'm going to have enough trouble making everything work on other platforms (esp. Windows) -- assuming the tool chain above is all correctly installed. So when people say 'use ledit' I have to ask: Why should I have to? Why isn't this functionality standard? Basically, I can't use Ocamlp4 in my project, because it adds yet another step into the tool chain. It looks frightening enough already. I do understand that Ocaml is basically a research project. And it is a superb package for production use as well, a rare combination! And I'm really happy that there is now a comprehensive compilation of third party libraries, (CDK) so that it is possible that step (d) above can be kept empty. -- John (Max) Skaller, mailto:skaller@maxtal.com.au 10/1 Toxteth Rd Glebe NSW 2037 Australia voice: 61-2-9660-0850 checkout Vyper http://Vyper.sourceforge.net download Interscript http://Interscript.sourceforge.net ------------------- Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr
