! LaTeX Error: File `algorithm2e.sty' not found.

During yet another LaTeX project on my MacBook, I added some algorithms to my paper. After checking a couple of examples online, and discussing with a colleage I decided to go with algorithm2e over others such as algorithm, algorithmic, algorithmicx, program and pseudocode[1].

However I got the following error "! LaTeX Error: File `algorithm2e.sty' not found." Since I am using macport, to resolve this I needed to install the texlive-science package by executing sudo port install texlive-science, and all was good again.

Springer Lecture Notes in Computer Science (LNCS) style

When working on a recent paper for a conference, I was required to produce it using the Spring Lecture Notes in Computer Science (LNCS) style. Being naive, I assumed TeX would automatically download the required package... unfortunately I got the following error "LaTeX Error: File `llncs.cls' not found." So I had to install the class manually. Here are the instructions for installing it on Mac OS X for latex from macport.

1. Download the llncs2e.zip package from the Springer website [1]
2. Unzip the file into the tex-live distribution location for macport, i.e. /opt/local/share/texmf-texlive-dist/tex/latex
3. Rebuild the ls-R databases using TeX by executing sudo texhash
4. To get the bibliography style setup, change directory by using cd /opt/local/share/texmf-texlive-dist/bibtex/bst
5. Make a directory to hold the style sudo mkdir splncs; cd splncs
6. Either copy or link the files sudo ln -s ../../../tex/latex/llncs2e/*.bst .

TexLive
If you are using a variant of TexLive such as MacTex, then you can copy the style files (*.bst) into "/usr/local/texlive/2012/texmf-dist/bibtex/bst/splncs" and the tex files into "/usr/local/texlive/2012/texmf-dist/tex/latex/llncs" and finally to update the ls-R database use "sudo /usr/local/texlive/2012/bin/x86_64-darwin/texhash"

IEEETrans on Mac OS X with texlive

While compiling a journal paper, I got the following error message "I couldn't open style file IEEEtran.bst"

The IEEETrans TeX distribution can be manullay installed by using the packages from CTAN [1] or  IEEE [2]. However since I use macports, I just had to;

1. sudo port install texlive-publishers
