I'm using LyX 1.6.9 with MikTex on Windows XP.

I want to use the "minted" package (for colored listings). This package uses Pygmentize to color the output. However, to do so, it uses \immediate\write18, which basically runs a command.

By default, Latex is not allowed to execute commands and throws instead the following error:

runsystem(echo testing)...disabled (restricted).

Turns out with Miktex on Windows XP, you must append a flag to the latex command which is to compile your code (cf. Using minted (source code LaTeX package) with emacs/auctex):


Since I'm using LyX, how do I add a flag / switch / option (whatever you call it) to the Latex command which compiles my LyX code?

I am very reluctant to navigating through Windows' CMD for all my further Latex compiling and I'm pretty sure there is a way to add that in LyX. I haven't found anything on their website nor on Google/Duckduckgo.

Any help will be appreciated. Thanks!

Under the Tools menu, choose Preferences. Then, in preferences dialog, under File Handling, in Converters, find the one for converting from TeX to PDF that you use (pdflatex, lualatex, xelatex, ...) and edit its command line.
