[HACKERS] RE: [HACKERS] Kerberos V5 required for PostgreSQL installation on Windows

2009-02-27 Thread Zeugswetter Andreas OSB sIT

We should delayload this dll since it is only needed
for specific configuration. No need to install when it is not used.

 If Kerberos V5 is not installed on a Windows platform, the following
 error dialog is returned upon attempted installation:
 
 Posgres.exe - Unable to Locate Component
 
 This application has failed to start because krb5_32.dll was 
 not found.
 Re-installing the application may fix this problem.
 [OK]

That would require building knowledge of DLL names into the code,
which isn't practical as some projects have a habit of changing them
regularly (e.g. gettext).

I'm not sure why Dann would see this problem - all our installers
include the required DLLs, and they should also be in the
binaries-no-installer packages. If he's built the binary himself, then
he obviously has the import libraries for Kerberos, so where are the
DLLs?

Are you sure?

http://msdn.microsoft.com/en-us/library/hf3f62bz.aspx

seems to indicate that you can do it on just the commandline if you want to?

(I haven't tried it so I don't know if it's actually doable)

That is also a valid question, though.

Hmm, didn't know you could do that. We'd still need code support to
figure out the DLL name from the import library so we can generate the
command line correctly though.

Yup, that is bad. Seems the krb5_32.dll name is quite stable though.
Not sure if you can specify a list of anticipated names ?

Oh, didn't know that. I guess that shifts it to pilot error then.
