Dear R developers, there is a problem if cairo is present but pango is not. The configure script tells very little about pango, there are two lines in the middle: checking whether pkg-config knows about cairo and pango... yes checking whether cairo including pango is >= 1.2 and works... yes But the final recap does NOT tell anything about pango, only about cairo: Additional capabilities: PNG, JPEG, TIFF, NLS, cairo, ICU The problem is, if cairo is present but pango is not, sometimes we are unable to plot, as R gives the message: |Path drawing not available for this device See here for more information: https://stackoverflow.com/a/45717473/1719931 If instead pango-devel is installed together with cairo-devel, the problem disappears and we are able to plot. I would request the configure script to be more explicit on whether pango is also present, by putting it in the list of "Additional capabilities" if it is present (next to cairo). So we know whether we will have problems in plotting or not. Best regards and thanks for your attention. | [[alternative HTML version deleted]]
