Hi there!
Ah, that makes some sense. So presumably there hasn't ever been a succe=
ssful build on AIX 6.1 using kerberos. Is it practical to try to build wit=
hout it?
Thank you!
-Ben

Ben,
The change that you referred to as being similar to the build failure on AI=
X is dated Sept 2013.
AIX 6.1 was last updated in November 2013. AIX 7.2 was first released in =
December 2015.
The initial use of krb5_c_make_random_key() was added to OpenAFS in 2007 bu=
t it was for test infrastructure which might not have been built for AIX. =
In the years since additional use of that function has been added to the so=
urce tree. However, it is unclear to me at least whether such changes were=
built on AIX.
The comments on https://gerrit.openafs.org/#/c/14707/3 which was the tip of=
the series that added symbols for AIX 7.2 state that the build on AIX succ=
eeded only if the kernel module was not built and if all linkage was static=
. That change series is a little over a year old.
The last combination that I can find evidence of the AIX kernel module work=
ing was OpenAFS 1.6.5 and AIX 6.1 TL5 which would have been 32-bit. OpenA=
FS 1.6.5 was released in July 2013.
And there was work needed for even that, given the incompatible struct mbuf=
changes that broke things across TL5
I would not expect 7.1 to work without at least some kernel changes.
