lhs2tex, Haskell Platform and cygwin
I just downloaded a fresh copy of Haskell Platform, and successfully got cabal to update itself. I installed smallcheck-0.4 successfully too. But then I tried to install lhs2tex, which 'worked' until the point of saying: Linking dist\build\lhs2TeX\lhs2TeX.exe ... Installing executable(s) in C:\Program Files (x86)\Haskell\bin setup.exe: The program mktexlsr is required but it could not be found And I do have 'mktexlsr' in my cygwin PATH (where I was running 'cabal install lhs2tex'). It's true that mktexlsr isn't in my Windows PATH. I would have thought someone else would have encountered this already, but my google searchers found other (long fixed) problems with lhs2tex under cygwin, but not this one. Jacques
From a runhaskell Setup.hs ... install it did have a couple of
Hi Jacques Does it install properly by the runhaskell Setup.hs configure / build / install? I re-installed it this way a couple of weeks ago and it never mentioned mktexlsr. problems which don't relate to your problem but seem worth enumerating here on the mailing list (so a Google search should pick them out). Unless lhs2TeX has been updated recently, it uses the old exceptions so I had to edit FileNameUtils.lhs. Also (on Windows) if your TeX installation has a space in the path, getting poly style to work will be challenging - the Setup.hs file has (had?) logic to reject 'bad' paths. Finally on Windows I was getting this error - the problem is actually with Windows and TeX (not lhs2TeX): ! Undefined control sequence. l.30 }\SkipToFmtEnd ? q OK, entering \batchmode Where the lhs2TeX manual gives these command to generate a file: $ lhs2TeX -o HelloWorld.tex HelloWorld.lhs $ pdflatex HelloWorld.tex On Windows, you need an intermediate step: $ lhs2TeX -o HelloWorld.tex HelloWorld.lhs $ dos2unix HelloWorld.tex $ pdflatex HelloWorld.tex Best wishes Stephen

No, it doesn't. I first run into issues with exceptions-related issues (as you did), which I solved via runghc Setup configure --constraint="base<4" But the install still failed on mktexlsr. So I tried runghc Setup configure --constraint="base<4" --with-mktexlsr="C:\\cygwin\\bin\\mktexlsr" runghc Setup build runghc Setup install but now I get a new error related to mktexlsr, namely $ runghc Setup install Installing executable(s) in C:\Program Files (x86)\Haskell\bin Setup: \cygwin\bin\mktexlsr: runGenProcess: invalid argument (Exec format error) mktexlsr is a /bin/sh script, so it's quite natural that an Exec on that would fail. So I'm still stuck. Thanks for the dos2unix pointer, that would have taken quite a while to figure out. Jacques

Ah ha - yes running mktexlsr is an optional step on page 5 of the lhs2TeX manual necessary to get the "poly" style. I tried a couple of hacks to the Setup.hs file to get poly running, but as I've MikTeX installed in a path with a space (and didn't want to re-install it), I decided I could live without poly and just have the simple styles.

Some success now. Reverting to building by hand, if I 1. edit config.ml to put "" quotes around the name of the GHC executable (since it contains spaces AND () ), 2. edit Makefile to add -package base-3.0.3.1 on to the --make line, things proceed through the build and install stage properly. For doing things by-hand, it would be nice if the 'configure' script automatically put "" quotes aroung the name of the GHC executable when generating config.mk. I took a look to see if I could figure out a patch to do that, but it wasn't obvious enough. Also, it would be nice if there were an lhs2tex version which worked out-of-the-box with base>=4, since hacking the Makefile for that seems, er, sub-optimal? Best would be if cabal was cygwin-friendlier. Unfortunately, that seems to be a lot easier said that done :-(. Now I have to see if 'poly' style *actually* works... Jacques

I've just uploaded 1.15 which should work better on Windows. Sorry, I should have released a new version a long time ago. Please let me know if this works. Cheers, Andres -- Andres Loeh, Universiteit Utrecht mailto:andres@cs.uu.nl mailto:mail@andres-loeh.de http://www.andres-loeh.de
