I found this package for latex that gives me the ability to typeset organic structural formulae and reaction schemes for chemistry. I'm having trouble with installing it though.

I read through the installation steps in the manual and it tells me that I need to edit the install.cfg.UNIX file which contains:

[PATH]
BINDIR=/usr/local/ochem
M4BINDIR=/usr/bin
INCDIR=/usr/local/ochem
DVIPSDIR=/usr/local/tetex/dvips/ochem
STYLEDIR=/usr/local/tetex/tex/latex/ochem
MODULDIR=/usr/local/ochem
DOCDIR=/usr/local/ochem/doc

[SYSTEM]
SYSTEM=UNIX

So I edited the file to this:

[PATH]
BINDIR=/usr/share/ochem
M4BINDIR=/usr/bin
INCDIR=/usr/share/ochem
DVIPSDIR=/usr/share/texmf-texlive/dvips/ochem
STYLEDIR=/usr/share/texmf-texlive/tex/latex/ochem
MODULDIR=/usr/share/ochem
DOCDIR=/usr/share/ochem/doc

[SYSTEM]
SYSTEM=UNIX

When I try to install the package, it says that it works, but when I try to typeset one of the examples, it tells me that it can't find ochem.sty. I then tried navigating to the directories that the install was supposed to make and they didn't exist. So I made the directories manually and tried the install again. I still get the missing ochem.sty error.

Did I edit install.cfg.UNIX correctly? My latex distribution is texlive 2009 on Ubuntu 10.10.

NOTE: I did try running sudo texhash and it still doesn't work.

EDIT: I did try running the install script as root, but it didn't work. Then I made the directories manually, and that didn't work either.

Here is the link to the package that I downloaded: http://www.2k-software.de/download/ochem_40d.zip

  • Probably a silly question: did you run the install script as root (or via sudo)? That it didn't create the directories makes me wonder about that. – Loop Space Dec 13 '10 at 21:55
  • Welcome to TeX.stackexchange! Please add a link to the package (the ochem package on ctan doesn't contain a file named install.cfg.UNIX) – Caramdir Dec 13 '10 at 21:55

    Maybe install.cfg.UNIX should be renamed to install.cfg? – Caramdir Dec 13 '10 at 21:56
  • Would you be willing to try another package? chemfig uses Tikz, and is part of TeX Live. – Torbjørn T. Dec 13 '10 at 23:08

    @Mica: this is not relevant here, since ochem is not included in TeX Live. – mpg Dec 14 '10 at 1:35

The following shell script install ochem from CTAN and the one you linked successfully into my TeXLive 2010 installation under Ubuntu Linux 10.10.

You most likely need to adjust the TEXLIVE and the BIN variables.

#!/bin/bash -x

TEXLIVE=/usr/local/texlive/2010/texmf-dist
SCRIPTS=$TEXLIVE/scripts/ochem
DOCS=$TEXLIVE/doc/latex/ochem
SOURCES=$TEXLIVE/source/latex/ochem
PACKAGE=$TEXLIVE/tex/latex/ochem
BIN=/usr/bin

mkdir -p $SCRIPTS
mkdir -p $DOCS
mkdir -p $SOURCES
mkdir -p $PACKAGE
chmod +x *.pl
cp *.pl *.pm $SCRIPTS
cp *.ps manual/* readme.txt $DOCS
cp *.tex *.inc $SOURCES
cp *.sty $PACKAGE

# Install scripts
cd $BIN
# Link makePics:
ln -s $SCRIPTS/makePics.pl makePics

# Generate wrapper for 'chemie.pl'
# Needs to get started with the '$SCRIPTS' folder as include folder
echo '#!/bin/sh' > ./chemie
echo "/usr/bin/env perl -I$SCRIPTS $SCRIPTS/chemie.pl" >> ./chemie
chmod +x ./chemie

# Ensure proper owner and permissions:
chown -R --reference=$TEXLIVE $SCRIPTS $DOCS $SOURCES $PACKAGES
chmod -R --reference=$TEXLIVE $SCRIPTS $DOCS $SOURCES $PACKAGES
chmod +x $SCRIPTS/*.pl
