Public bug reported:
I'm trying to draw a simple chemical structural formula using LaTeX
style chemfig.sty (included in texlive-science), however upon displaying
the graphic all the elements are superimposed on top of each other. I'm
using LyX as a frontend, I've added \usepackage{chemfig} to the LaTeX
Preamble, and I've input the following LaTeX:
\chemfig{C([2]H)([4]H)([6]H)C([2]H)([6]H)H} <--This aformentioned
ChemFig structural diagram is an example from section 3.1 of the ChemFig
documentation v1.0f published Feb 24, 2012. I thought this might be an
issue with my LaTeX installation, so I removed/purged and reinstalled:
# sudo apt-add-repository ppa:texlive-backports/ppa
# sudo apt-get autoremove --purge texlive texlive-science texlive-pictures
texlive-pictures-doc texlive-latex-extra-doc texlive-generic-extra
texlive-science-doc libreadline5 tex-gyre libruby1.8 tk8.4 tcl8.4 libkpathsea6
libptexenc1 ruby ruby1.8 ttf-marvosym libgraphite3 tex* libdigest-sha*
# sudo apt-get autoremove
# sudo apt-get clean
# sudo apt-get update
# sudo apt-get autoclean
# sudo apt-get check
# sudo rm -rf /etc/texmf
# sudo rm /var/lib/dpkg/info/tex*
# sudo dpkg --purge --force-all tex*
# sudo apt-get -f install
# sudo apt-get install texlive-latex-recommended texlive-latex-extra
texlive-science texlive-generic-extra perl-tk libdigest-sha-perl
Even upon reinstalling texlive and related packages, the problem of
ChemFig graphics superimposing upon itself into a garbled mess persists.
It matters not if I export with pdflatex. Please see attached graphic,
it shows the display of the previous mentioned example on the left, and
another example from the ChemFig documentation on the right:
\chemfig{[:30]RC[::60]C([::60,,,,rddbond]O)[,,,,lddbond]N([::60]H)[::60]CR}
