[HTCondor-users] building HTCondor 7.9.6 on Mac OS fails, _res_9_init undefined

[Leo Singer <lsinger@xxxxxxxxxxx>]

Hi,

I am having some difficulty building HTCondor 7.9.6 on Mac OS. In fact, I am attempting to update the MacPorts package. The build fails here:

Undefined symbols for architecture x86_64:
  "_res_9_init", referenced from:
      DaemonCore::refreshDNS()       in libcondor_utils_7_9_6.a(daemon_core.cpp.o)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[2]: *** [src/condor_shadow.V6.1/condor_shadow] Error 1

I'm no expert on CMake internals, but the file src/condor_shadow.V6.1/CMakeFiles/link.txt, which seems to contain the linker command, does not contain a '-lresolv' flag. It seems like it should, because this is where res_9_init is defined:

$ nm /usr/lib/libresolv.dylib | grep res_9_init
000000000000dc4c T _res_9_init

Is this a plausible diagnosis? If so, is there a workaround?

Thanks,
