Buildng for Windows

[pbcole]

Hi,

I'm trying to get rkerberos to build on Windows 7, so far without any luck.
I have the krb5-1.13.1 from MIT built and installed.
When I try to run either "gem install rkerberos", or rake test in the gems directory, I get:

--- 8< ---

Any sugestions?

I'm not very familiar with ruby, so apologies if I'm missing anything really obvious.

If you have the gem installed, then you don't need to rebuild. You could just do "ruby -Iext test/*.rb" I think.

If you want to run the rake task, you'll have to pass the options that you passed on the command line to build rkerberos in the first place. So, something like "rake test -- --with-rkerberos-dir=C:/path/to/kerberos".

Hi,

Thanks for the reply. I'll take a look on Tuesday when I'm next back at
work.

I haven't yet been able to get the gem to install... as it's failing at
this step during installation. I'll see if I can get the command line
passed on the gem install line.

Cheers

Phil

Ah, it didn't successfully install. Ok, then try "gem install rkerberos -- --with-rkerberos-dir=C:/path/to/kerberos".

[djberg96]

Any luck?

[pbcole]

Sadly not... at least not yet.

I haven't been able to upload the logs to somewhere I can share with you

• I'll have a go again at that tomorrow (the joys of restricted networks!)

I think the problem is that some parts of the kerberos codebase may not
be as cross-platform as one would like, so it ends up trying to look for
linux/unix headers on a windows system :(

The only includes in rkerberos are these:

#include <ruby.h>
#include <krb5.h>
#include <string.h>

#ifdef HAVE_KADM5_ADMIN_H
#include <kadm5/admin.h>
#endif

None of those are unix-specific, so I'm guessing it's something else. Anyway, we'll take a look at the logs once you post them and see what we can do to help.

Oh, nm, you mean within kerberos itself. Hm, could be, I don't think I ever tried to build it on Windows.

[djberg96]

Just curious, did you build from source or use one of the kerberos installers? Because I noticed that the installer doesn't include the admin headers for some reason.

[pbcole]

I built from source, so have all the libraries and header files available.

The problem is a header imported from kadm5/admin.h.
admin.h includes gssrpc/rpc.h
which includes netinet/in.h

which isn't available on Windows :(

Hmm, could be a bug in kerberos. What happens if you explicitly include winsock2.h in rpc.h before that line?

Edit: Or maybe substitute netinet/in.h with winsock2.h, can't remember now.
