Pkg exim4 users - Jan 2007 - Compiling Exim4 from source for Domainkeys

I''m getting around to signing email that I send to Yahoo.  The
path is still rough for us novices, at least for Exim.  Qmail is
probably the better choice, however I''m most familiar with Exim.

I have found an unofficial domain keys library for Debian at

	http://www.kibibyte.se/download/debian/
	
There seems to be a license issue, and I''m not sure why Yahoo is
making things difficult if they want us to sign email going to
them.  Any license fees somebody would pay pale in comparasion
to reducing spam costs for them.

I can get libdomainkeys0_0.68-1_i386.deb installed, but I don''t
know how to figure out where it went.

I need to know where it went to give me some chance of adjusting
the CLFLAGS and LDFLAGS statements, that I need to add to the
Local/Makefile.


EXPERIMENTAL_DOMAINKEYS=yes
CFLAGS  += -I/home/tom/exim-cvs/extra/libdomainkeys
LDFLAGS += -ldomainkeys -L/home/tom/exim-cvs/extra/libdomainkeys


What Debian command would show me where a package gets installed
at ?

And if that doesn''t give me the answer to CFLAGS and LDFLAGS, I
would appreciate the answers straight out.

Thank you.

p.s.  Or are we supposed to be using DKIM instead of Domainkeys ?

That would be me who is to blame. :-)

Well, the issues are mainly 1) that the license isn''t DFSG compliant
and 2)
that it''s unclear whether the library can be packaged using the word 
domainkeys in the package name. Yahoo *probably* isn''t going to make
things
difficult to anyone, but Debian wants to be sure in order to distribute a 
package.

You also need to install the -dev package to build programs using the library.

I was meaning to include a .pc file containing the necessary compiler and 
linker flags in a future version. Since the header files are installed 
in /usr/include and the .so file in /usr/lib, you only need

EXPERIMENTAL_DOMAINKEYS=yes
LDFLAGS += -ldomainkeys
> What Debian command would show me where a package gets installed

In general you can see what files a Debian package contains by running

$ dpkg -L package

after installing it, or

$ dpkg -c packagefile.deb

before installing it.

DomainKeys has been superseded by DKIM, which differs from DK in certain ways, 
dealing with some shortcomings of DK (for example, DK requires that the 
Sender field be changed if a message needs to be re-signed), but Yahoo still 
only uses DK.

Magnus

Thanks for doing all the work of building a Debian version of  
DomainKeys.

It''s tough to "blame" computer geniuses that do good work for
free :-)

In my case I did get a B in Com Sci 101, but flunked Com Sci 102.   
Twice.

So when things get more complicated than apt-get install, I have a  
difficult time keeping up.

IMHO, sometimes it''s better to ask for forgiveness then permission.   
I mean if Yahoo came
and said take our code out of your distribution, then by all means  
comply.  I just can''t see
Yahoo suing anybody in this case, and if they did it would be great  
publicity for Debian.
Just look at how much free publicity Apple got on the iPhone when  
Cisco sued them
last week.

Last month another package that I use to keep out viruses was dropped  
by the Debian
developer because he did not feel that the documentation had the  
appropriate copyrights.
The source code was clearly marked as GPL, and it''s been a free and  
open source
project it''s whole history, and it''s been in Debian for 5
years or so.

So I do feel that Debian is making mountains out of molehills,  
especially where the
intent of at least these two projects is clearly to be used freely by  
everyone.

These days the Internet is in crisis mode with all the spam,  
phishing, keystroke loggers, etc.
and the more people that can administer a Linux system the better for  
everybody.

So for every hurdle that Debian leaves up, it keeps a certain  
percentage of us
regular people from using tools that are important to the Internet''s  
health.

While compiling a package from source is a piece of cake for most of  
you guys, it''s
probably going to take me 8 hours to figure this out, and that''s if  
I''m having a good
day :-)

So if Debian is going to do all the computer science work of making  
these package
easy to use, I think Debian should have the balls to release them  
even if all the i''s are not
dotted, and t''s crossed.

I realize that this mailing list is probably not the place for my  
ranting, and if somebody
wants to point me to an appropriate place, I will be happy to try and  
impart some
common sense and intestinal fortitude  to people making these sorts  
of decisions.

Ahhh, I see.  Thanks for that clue.

I did find the libdomainkeys0 in /usr/share/doc, but it really didn''t  
have any clues for
somebody at my level.

Can I take http://www.kibibyte.se/download/debian/ and add that to my
/etc/apt/sources.list somehow.  And do apt-get installs''.

Or do I need to ftp the packages and install them with dpkg.

I have no idea what a .pc file is but anything you can do to make it  
easier
is much appreciated :-)

That''s the answer I''m looking for, thank you very much.

Thanks I must have tried 4 or 5 commands like show and stats without  
success.

That''s good to know.  In my case I''m just trying to make Yahoo
happy,
at least for
the moment.

Thanks for making a Debian package available and answering my questions.

Sorry, I haven''t set up a proper repository yet, so that''s
unfortunately not
possible.

Many -dev packages include a program named <package>-config, which answers
questions like "which configuration options were used when building the 
package" and "which flags do I need to compile and link with a
library".
pkg-config answers the second question by reading a file of a standardised 
format, so that you can say

LDFLAGS += `pkg-config --libs libdomainkeys gnutls someotherlib`

etc, and get all the parameters needed.

For your information, I do have a more or less proper repository now. Its 
canonical URL is ftp://ftp.kibibyte.se/debian/, and while I only have 
packages for sid and experimental and compiled for i386, I intend to build 
packages for testing and stable as well, when relevant. The "www" URL
above
is hereby deprecated.
