Re: [ptxdist] Runtime dependencies generation

["Benoît BURNICHON" <Benoit.BURNICHON@airtag.com>]

Thanks a lot, it was exactly what I needed to know.

Btw, a very small hack to have barebox-XXX.ipk package selected (which in my case contains bareboxenv utility for target)

In menu, although barebox bootloader is selected, it is not seen by the Kconfig:
/home/bburnichon/workspace/ptxdist-2011.01.0/rules/mypackage.in:5:warning: 'select' used by config symbol 'MYPACKAGE' refers to undefined symbol 'BAREBOX'

Rules/barebox.in:
------8<---------8<---------8<---------8<---------8<---------8<---------8<---------8<---------
## SECTION=shell_and_console

+config BAREBOX
+        tristate
+
config BAREBOX_TARGET_BAREBOXENV
        prompt "Install target bareboxenv"
+        select BAREBOX
        tristate
        help
          To be able to modify barebox's settings at Linux's runtime enable
          this item. It will install the 'bareboxenv' tool to /sbin
