hints for compiling Arla on OS X 10.3

[Paul Swenson]

I've successfully gotten the latest alpha build (arla-0.36pre40) to build on Panther using the instructions provided here (#undef HAVE_KRB5 in the two files). Arla installs fine, the kernel modules loads, and I can browse AFS space. The only problem is, Arla didn't seem to compile the aklog command to transfer kerberos tickets to AFS tokens. I linked Arla against the krbafs library so I can use the built-in MIT Kerberos to obtain tickets. In previous releases of Arla in 10.1 and 10.2, this setup would cause aklog to be built along with the rest of the CLI utilities. I've tried building it by hand and via some makefile hacking, and can get it to compile, but it doesn't seem to succeed in obtaining tokens (it always fails with a "aklog: Failed getting tokens for cell umbc.edu", I am using the exact same edu.mit.Kerberos and arla config files that were working before). I believe this has something to do with the changes I had to make in order to allow it to compile. First, I added a #include <krb.h> to the top of aklog.c, and then added a #define HAVE_KRB_AFSLOG_UID, since I was getting an undefined symbol error when it was trying to call k_afsklog_uid in the krb_afslog_uid function (I couldn't find a reference to this function anywhere in the included kerberos libraries or libkrbafs). I also tried replacing the call to k_afsklog_uid with krb5_afsklog_uid and a few other things, but most of my attempts resulted in either failures, segfaults or an inability to compile ;-). Does anyone have any suggestions of how to build a working aklog from the 0.36 alpha sources in Mac OS X 10.3? I believe this is the final step in getting a working AFS client in Panther. Once I get this working, I plan on putting together an installable package preconfigured for other Mac users at UMBC.

Thanks in advance!
