[Boost-users] Re: about license

A little late to this license party, but I want to make sure I know what it means: David Abrahams wrote:

Hi-

I am considering using boost in my applications, but I have a question about the boost license at http://www.boost.org/LICENSE_1_0.txt . It says (edited) "Permission is hereby granted, free of charge, to ... use [and] reproduce ... the Software".

It also says that any derivative works must also have the same license grant.

If my application uses boost libraries unchanged, is it considered a derivative work?

Yes.

...

If so, does that mean that if I distribute my compiled software, I must allow free of charge use and distribution?

No, the license gives an explicit exemption for compiled code

So if we use boost in our program: 1] If we sell it as a compiled program, we can retain our own license 2] If we sell it to a customer who wants the source code too, we have to use the boost license, and thus the customer is free to give our source code away at that point? -- Jonathan Arnold (mailto:jdarnold@buddydog.org) Daemon Dancing in the Dark, a FreeBSD weblog: http://freebsd.amazingdev.com/blog/
