Hello, For ‘r’, the *Guix Package Info* buffer omits IcedTea from the set of inputs. It shows this:
--8<---------------cut here---------------start------------->8--- Inputs : openblas-0.2.14, cairo-1.14.2, gfortran-4.9.3, icu4c-55.1, lapack-3.5.0, libjpeg-9a, libpng-1.5.21, libtiff-4.0.3, libxt-1.1.4, pcre-8.37, readline-6.3, zlib-1.2.7 --8<---------------cut here---------------end--------------->8--- whereas the recipe has this: --8<---------------cut here---------------start------------->8--- (inputs `(("openblas" ,openblas) ("cairo" ,cairo) ("gfortran" ,gfortran) ("icu4c" ,icu4c) ("icedtea6" ,icedtea6 "jdk") ("lapack" ,lapack) ("libjpeg" ,libjpeg) ("libpng" ,libpng) ("libtiff" ,libtiff) ("libxt" ,libxt) ("pcre" ,pcre) ("readline" ,readline) ("zlib" ,zlib))) --8<---------------cut here---------------end--------------->8--- My guess is that somewhere, the triplet for IcedTea is silently filtered out. Thanks, Ludo’.
