We could drop the patch or we could update the patch to add '-ldl' to LIBS in
build system. I'm undecided, and atm extremely burnt out with real life work,
so am looking for some advice.
08_pcsc_dynamic.patch is untested by anyone, not very beautiful looking. Also
it seems up to me to push to upstream, which I'm not totally confident about.
Further to the problem, upstream build system seems not to add '-ldl' to LIBS
for BSD configurations. For example:
$ grep -A1 -B1 '\-ldl' wpa_supplicant/Makefile
ifndef CONFIG_DRIVER_BSD
LIBS += -ldl
endif
--
ifneq ($(CONFIG_L2_PACKET), freebsd)
LIBS += -ldl
endif
I do not know why this is the case, and I think this will come up if I was to
push this patch upstream. There are multiple places in which this linker flag
gets added to LIBS for non BSD configurations which is why we did not witness
this build failure on linux before now.
Attached is what I drafted up in working copy of pkg-wpa SVN in response to the
FTBFS notifications some days ago, comments about how to proceed are very
welcome. I know Stephan's inclination is to drop the patch and let someone
with the hardware and know how fix up the problem in the future.
Thanks, Kel.
