LGPL 2.1 or later according to my RPM package.

OK, I'll assume you didn't read the link that started the thread, then. Thanks.

And GPL != LGPL. LGPL is GPL plus ability to use the library unmodified in 
commercial applications. The GPL doesn't allow you to link to unmodified GPL 
code and use it in your own program.

I'm pretty sure it does, yes.

Why would you need "a linking exception to the GPL" if the GPL didn't infect 
linked software?

If I'm using your "main", it's arguably your program. :-)

What if I take some of the "bunch of other functions" you wrote that you 
provided in a separate library, which I don't need to modify at all to 
invoke from my program?  That's what we're talking about.

Yes.

Sure. But if the license already covered plug-ins, they wouldn't need to 
extend it. The owners of the Linux copyright could change the license to say 
you're not allowed to run any proprietary software under Linux, and you 
can't run Linux on any machine that had ever had Windows installed, too. 
That doesn't mean it's a *good* thing.   I'm not denying their *ability* to 
do this.

This is contrary to other discussions I've read on the topic.

If you include code I wrote in your code, then you have to respect my 
wishes about the use of the code.

Sure.  What ultimately may come out of the whole GCC kerfuffle is another 
compiler without those restrictions, if the folks over at the FSF insist 
on putting stupid restrictions in place.

Someone very likely will fork an older version of the code (pre-stupid-
restrictions) and "the market" (whatever that means) will decide whether 
the stupid restrictions are worth the hassle or not.

Don't be naive, Darren.  He's telling it's your choice to write and release a
plugin for GCC under the GPL.  You can simply give them the finger, fork it,
start from scratch or use the intel compiler.

Which BTW is free for *use* (but not modification) as long as it isn't *used*
for commercial work, like the free compiler from Microsoft too.  Which reminds
me that this is an important distinction for the word *use* indeed.  Use of
software always reminds me of users, not software developers trying to "use" it
as the secret engine of their closed app...

Thanks.

Don't assume. You want to release code mixed with GPL code, but don't want
to be bothered by respecting the licensing terms of the authors who came
before you, created that piece of code you find irresistible to use, and
GPL'ed their work. Don't know how I can help you there, but here are your
options:

1) Write your own code from the ground up. Pick whichever license makes you
happy.
2) Don't release code which is based on or interfacing with GPL'ed code. You
can still use it for personal needs.
3) Respect the GPL license of the authors whose code you are using, and
contribute your code as GPL.
4) Don't write any code at all, become a used car salesman.

Notice how "have your cake and eat it too" is not a legitimate option.

From your POV. From the POV of all developers taken as a whole, or from the
POV of the original authors, code that's infectuously free may be more free
than code that's currently free.

I'm not. I'm saying that if I write a plug-in for GCC and release it, it'll 
break if it's not GPLed. I don't know how that isn't the FSF making me 
release my code as GPLed in practice.

But, we've clearly reached the end of any reasonable conversation about the 
topic now.

No, I don't! That's exactly what the article is talking about! I want to 
release code that I wrote 100% myself that includes no source or object code 
that anyone else has written. And the FSF is trying to find a way to force 
me to release that as GPL by crippling their own software.

> 2) Don't release code which is based on or interfacing with GPL'ed code.

How come I can write code that interfaces with Linux without violating the 
GPL, but I can't write a plug-in for GCC without violating the GPL?
