Library name change...

How would people feel about just changing the names of all of the libraries
to, eg, libkst2math, etc, to totally avoid the issues of compiling 2.0 when
1.x is installed.  

It seems like a hack, but... life is short.

Opinions/advice?

Does anyone other than kst ever link to these libraries?  If not, I
don't see why you couldn't name them after, say, your former graduate
students.  Aren't these rebuilt wiht every kst release?  Why not embed
the full version string in the file name.  Then you're certain you're
getting the right library.

They are used for linking to plugins and datasources, which someone, might
write.

Hmmm... interesting.

Maybe...

In that case, adding "2" might be a good idea anyways.  Presumably if
kst2 can't be linked against kst1 libraries, kst2 plugins couldn't be
able to either?  Unless the APIs are similar enough that porting from 1
to 2 is "easy"...?

I know!  Good idea, right?

I thought in such a case one would use names like libkstmath.so.2
instead of libkst2math.so (under Unix, no idea how that works under
Windows though). Sticking to the standards seems preferable to me, as
long as it also works under Windows. By the way, kst 2.0.0 beta3
compiles fines out of the box under Windows with Qt Creator (not really
tested yet, but it's nice to have it compile :-))

I agree.  The problem is, under some distributions (eg, slackware, or suse),
if /usr/lib/libkstmath.so.1 is installed at build time, it is picked up by the
linker.  I can't figure out how to tell the linker to only look in the build
directory for some libraries, and not for others.  Interestingly enough, if
the linker links to 2.0.0, then even if the 1.x libraries are later installed,
everything works fine.

This is has actually been a long time problem.  If you have kst installed on
your system, and do a build, the linker links to the libraries in /usr/lib,
rather than the ones in the build directory...  If we were maintaining binary
compatibility, this wouldn't be a problem for users upgrading - the install
stage would just overwrite the old libraries and no-one would be the wiser.  
But it is a pain if you are developing kst on the same machine you are using
it, or if we break binary compatibility, which we do from time to time.

I have seen distributions do this name change hack to get around these sorts
of troubles before, so I think there may not be a clean solution.

My son is hoping to prepare a windows package to go along with the release....
which will be... soon.

Cool.  Please tell Josh to make sure that there are many silly options
in the install wizard which everyone will always just keep clicking next
as fast as possible until it starts to install.  That's the Windows Way™.
