I'm writing a package that I hope to make available on CRAN. The package interfaces to the FAME database via a .so file supplied by FAME, which should be loaded in the package .onLoad() function. Unfortunately, so far as I know, there is no standard location where this .so file can always be found. So I need to have some way for the package installer to indicate where the file can be found. Also, FAME needs stuff from either the Motif or LessTif library, so I have to make sure that one of them can be found via the LD_LIBRARY_PATH. (Just why FAME needs this stuff when there's no user interface involved is a question to be pondered for the ages.) So I need a way for the package installer to supply the locations of the FAME hli library (the .so file) and the location of the Motif/LessTif library directory. How should I do this? I'd rather not assume that either the installer or the package writer (me) know much about autoconf. Can I get away with a simple text file in the 'inst' directory, or will CRAN reject my package if I do it that way? Jeff
