Bug 2723

Two related items:

If baselib != "lib", there is a check in

> python package_do_shlibs() {
>          import re, pipes
>
>          exclude_shlibs = d.getVar('EXCLUDE_FROM_SHLIBS', 0)
>          if exclude_shlibs:
>                  bb.note("not generating shlibs")
>                  return
>
>          lib_re = re.compile("^.*\.so")
>          libdir_re = re.compile(".*/lib$")

The check should really be (or similar):

re.compile(".*/%s$" % d.getVar('baselib', True))


Then once the additional libraries are found, the ldconfig call will be automatically added..  the second issue happens when this call is made in a filesystem that does -not- contain ldconfig:

The problem is, at least in the case of RPM, the shell is run to check for non-zero return codes.  The [ -x /sbin/ldconfig ] returns non-zero, so the && never runs.. but the status is also never cleared.  This leads to an install failure.

My suggestion is to replace the line with:

if [ -x /sbin/ldconfig ]; then /sbin/ldconfig ; fi
