On the one hand, gv is a postscript viewer and has no control over what fonts it might be asked to display. On the other hand, gv is intended to be run under X11, so maybe it should require the most basic X11 fonts. gv requires ghostscript which requires ghostscript-fonts-other and urw-base35-fonts which should provide a fallback from Helvetica to Nimbus. Perhaps for older apps and documents urw-base35-fonts-legacy could or should (also) be included? Could that solve the problem, or would it still require xorg-x11-fonts-dpi{75,100)? -- La perfection est atteinte, non pas lorsqu'il n'y a plus rien à ajouter, mais lorsqu'il n'y a plus rien à retirer. -- Antoine de Saint-Exupéry -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
Re: Frequent Warning messages using gv
Thank you. Installing these two packages has done the trick, at least for the several files that previously generated warning messages.

I'm not familiar with gv, but this looks like you're trying to process documents that incorporate Helvetica, in a way that requires having the font files, without having the font files. Helvetica is a trademark, and the font files are under copyright, so no Cygwin package is going to be able to include the fonts or even include substitutes with matching filenames. You *might* be able to add symlinks from the missing Helvetica files to more readily available metric-identical alternatives you already have access to, e.g. Arial, MS Sans Serif, or Liberation Sans. Otherwise I suspect you need to either avoid processing files that incorporate fonts you don't own, or buy copies of the relevant Helvetica typefaces. Something I might try first is researching how fontconfig can allow you to set up substitutions.

Frequent Warning messages using gv
