Re: Right way: define, build and install

[Jone]

But I am ashamed! :)

1. xfce4-cpugraph-plugin.scm

(use-modules (ice-9 match)
             (srfi srfi-1)
             (guix gexp)
             (guix packages)
                         (guix build)
             (guix licenses)
             (guix git-download)
  (define-public xfce4-cpugraph-plugin
  (package
    (name "xfce4-cpugraph-plugin")
    (version "1.0.5")
    (source (origin
              (method url-fetch)
              (uri (string-append "http://archive.xfce.org/src/panel-plugins/";
                                  name "/" (version-major+minor version) "/"
                                  name "-" version ".tar.bz2"))
              (sha256
               (base32
                "1izl53q95m5xm2fiq7385vb1i9nwgjizxkmgpgh33zdckb40xnl5"))))
    (build-system gnu-build-system)
    (native-inputs `(("pkg-config" ,pkg-config)
                     ("intltool" ,intltool)))
    (inputs `(("glib" ,glib)
              ("gtk+" ,gtk+-2)
              ("libxfce4util" ,libxfce4util)
              ("libxfce4ui" ,libxfce4ui)
              ("xfce4-panel" ,xfce4-panel)))
    (home-page
     "https://goodies.xfce.org/projects/panel-plugins/";)
    (synopsis "cpugraph")
    (description
     "TEST")
    (license (list gpl2+ lgpl2.0+))))
)

2. Then in terminal

GUIX_PACKAGE_PATH=/home/jone/sys.cfg/build/my/ guix package -i 
xfce4-cpugraph-plugin

ERROR: In procedure %resolve-variable:
libxfce4util: unbound variable
