Hi,

1. I wrote the recipe .bb to install the nano editor, the contents given
below,


 1 SUMMARY = "GNU nano- editor"

  4 HOMEPAGE = "https://www.nano-editor.org/"
  5 BUGTRACKER = "https://savannah.gnu.org/bugs/?group=nano"
  6
  7 SECTION = "console/utils"
  8 PRIORITY = "OPTION"

 12
 13 DEPENDS = "ncurses"
 14
 15 PV_MAJ = "${@bb.data.getVar('PV',d,1).split('.')[0]}"
 16 PV_MIN = "${@bb.data.getVar('PV',d,1).split('.')[1]}"
 17
 18 SRC_URI = "https://www.nano-editor.org/dist/v${PV_MAJ}.${PV_MIN}/nano-$
{PV}.tar.gz"
 19 #SRC_URI = "https://www.nano-editor.org/dist/v2.3/nano-2.3.1.tar.gz"

 21 SRC_URI[md5sum] = "af09f8828744b0ea0808d6c19a2b4bfd"
 22 SRC_URI[sha256sum] =

 26 RDEPENDS_${PV} = "ncurses"


2. When I run the bitbake nano, the am getting the error as given below,

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

3. Could not get the solution, any help here. Any patches needs to appy
