Running CWEAVE.exe and CTANGLE.exe on MPlib sources (under Windows)
by Graham Douglas 05 May '10

05 May '10

Hi All I guess one is for Taco... Hope OK to ask this here. I'd like to build MPlib as a DLL using the discussion you posted here: [reproduced below] http://www.dw.tug.org/pipermail/metapost/2010-April/001917.html (reason: to probe a bit more into the btex...etex + makempx stuff) (For this build I want to use visual C++) I've tried to run both ctangle.exe and cweave.exe on the .w sources. These exes were both built during the MPlib build. No matter what I try to do, they both fail with the errors below. From a pure DOS shell or an Mysys bash shell --- simple paths or not. Is this caused by Default CHANGEFILE is /dev/null; --- which confuses windows? Any suggestions would be great :-) Could I just use the code from the MPlib build process as output to \build\texk\web2c\ =--> Are these files identical to what you would get from running ctangle.exe or are they processed during the build process? \MPlib\build\texk\web2c\memio.c \MPlib\build\texk\web2c\mp.c \MPlib\build\texk\web2c\mpost.c \MPlib\build\texk\web2c\mpxout.c \MPlib\build\texk\web2c\psout.c \MPlib\build\texk\web2c\svgout.c Apologies for what must be quite trivial questions for you Taco but the whole Web2c paradigm is still rather alien to me so I would value your comments, as always. Warm wishes Graham ================================ $ cweave c:/mpxout.w This is CWEAVE, Version 3.64 (Web2C 2010/dev) ! Cannot open change file NUL. (l. 0) (That was a fatal error, my friend.) G:\MPlib\source\texk\web2c\mplibdir> ctangle G:\MPlib\source\texk\web2c\mplibdir\mpxout.w This is CTANGLE, Version 3.64 (Web2C 2010/dev) ! Cannot open change file NUL. (l. 0) (That was a fatal error, my friend.) =============================================================== > 1) How to build MP as *.dll (win) or *.so (linux)? Metapost consists of two components: a library and an executable driver. The library is built from am/libmplib.am, the executable from am/mplib.am. The library consists of avl.c, memio.w, mp.w, psout.w, and svgout.w, this does all the real work except the TeX connection and file searching. The binary has mpxout.w and mpost.w, and connects the library to kpathsea. There is also lmplib.c. This file creates bindings to the library component from lua, and could be used as an example. If this is too obscure for you, see manual/mplibapi.tex for the official documentation. The current build system does not support creating a dynamic library (because it is derived from the TeXLive build system which does not need that) but the general approach is fairly straightforward: run 'ctangle' on memio.w, mp.w, psout.w, and svgout.w, then compile the resulting C files + avl.c into a dynamic library using whatever methods you need for your platform. > 2) I don't need an TeX-ability with MP (no texts at all). How to > build MP without TeX connection (kpathsea and others)? This is automatic if you only build the library part: when the relevant callback functions are not set, the library disables btex .. etex processing and will only be able to use files from the current working directory. Best wishes, Taco Pasted from <http://www.dw.tug.org/pipermail/metapost/2010-April/001917.html>

MPlib and btex...etex
by Graham Douglas 02 May '10

02 May '10

Hi All I have a quick question about the behaviour of btex...etex. The code below works perfectly until I include any mp code which make use of btex...etex. I keep getting errors like this: >> mapmax.mp >> mapmax.mpx ! Unable to make mpx file. l.383 l abel.bot(btex $\reals$ etex, q+(0,-b)); I am running a slightly older version of LuaTeX on Windows Vista Version beta-0.53.0-2010032719 I am NOT using ConTeXt but simply using a version of Plain. Just for the record I do all MetaPost PS --> PDF with a call to GhostScript via a Lua binding. I think that in the "old days" all the btex/etex stuff was handled by a set of calls to an external program which processed the DVI -- makempx or something like that?? Can anyone tell me how MPlib now handles btex...etex so that I can try to figure out why it might be failing. I'm not sure but it may be that some calls to making temporary files are failing, but that's just a guess. Any insights into the low level btex...etex machinery would be great. Many thanks to all and best wishes Graham ===== ========================================== Test MP code ========================================== local function finder(name, mode, ftype) local found if mode=="w" then found = name else found = kpse.find_file(name,ftype) end if found then print("MPlib finder: " .. name ..
