Re: AIX build fails with missing symbol .krb5_c_make_random_key

Hi Ken-

Ah, yes, I believe you are right.  That library does exist on my system also, and I manually added it to Makefile.config and the build continued.  The question is then, why didn't ./configure detect it and add it?

I think this is the problem:

$ grep md5 config.log
configure:41845: checking for krb5int_hash_md5 in -lk5crypto
ld: 0711-317 ERROR: Undefined symbol: .krb5int_hash_md5

For some reason, the check for if we should add -lk5crypto is failing.  There's a krb5int_hash_md5 but not a .krb5int_hash_md5.  Should we check for something else on AIX?

Thank you.

Are you _sure_ that libkrb5.a has that symbol in it, and it's not just
an undefined reference to the symbol?  On my system (using MIT krb5 1.19)
krb5_c_make_random_key is in libk5crypto, and I noticed that library is
not in your link command (there are references to krb5_c_make_random_key
in libkrb5, but no symbol definition).
