The GPL libraries that I've used personally simply stipulate that: a) You state in the program's documentation or "About" box that the library is being used by the application. b) You tell anyone who asks where to get the source code for the library. Using such a GPL library does not make your code GPL. Perhaps there are GPL libraries which do have that stipulation, but I've not encountered them if there are. |

Libraries are often placed under Lesser GPL, called LGPL.
As stated on Wikipedia, in http://en.wikipedia.org/wiki/LGPL , " The main difference between the GPL and the LGPL is that the latter can be linked to (in the case of a library, 'used by') a non-(L)GPLed program, which may be free software or proprietary software [1]. This non-(L)GPLed program can then be distributed under any chosen terms if it is not a derivative work. " |

Thanks, Krystian - that must be what the libraries I've used have been released under.

They could, at least, say who their suppliers are and state something like "for obtaining the source code of the GPL parts, please address to This and That, ltd." |

So anybody reported them to www.fsfeurope.org yet ?
I asked for the kernel source the day I bought my Cybook and never got a response from Bookeen. |

And the case I spoke of is specifically code that links against the Linux kernel. This would include device drivers (which become part of a running kernel), but exclude applications programs, which just call kernel services. ______ Dennis |

It's obviously the LGPL which I've come across with the GPL'd utility libraries that I've used, rather than the "full" GPL. Thanks for the clarification.

One of the things I run here is Cygwin, a port of the Gnu toolchain to Win32, available as a free, open source offering under the GPL. Rather than rewrite every utility to use Win32 system calls instead of *nix calls, the developers wrote a POSIX compatibility library implemented as a DLL, containing a subset of the most used *nix system calls. Lots of *nix code builds "out of the box" under Cygwin, because the code links against the Cygwin1.dll, and sees the *nix routines it expects. A full Cygwin install includes the GCC compiler suite. One of the questions on the Cygwin mailing list is "Can I use Cygwin GCC to build closed-source code?" The answer is "Yes, if you use the MinGW version, which links against the Microsoft runtime rather than the Cygwin version." Linking against the Cygwin1.dll would make your code GPL, but the MS runtime does not, and there is no requirement on GCC itself that you may only build GPLed code with it. Another common question is "If I write GPLed code, must I distribute the source with it?" The answer is "No. You simply have to be willing to provide it, and must inform the user you will do so and state how to get it. You must be careful, because the user should be able to use the source you supply to duplicate the binaries you created, so the source you provide must be the source that created those binaries. But you are not required to provide the source in the same distribution as the binaries. Most users won't want it and wouldn't be able to use it in any case. You simply must provide it on demand, in a convenient form for the user." ______ Dennis |

Nope. I'd sell it after stripping out the ebooks, music and images I had put on. As for the firmware, since I'd be also ridding myself of the hardware it was installed on, I'd be okay with leaving the firmware in place. Derek |

Just so that you realize that this is selling something you do not have the permission from the copyright holder to sell. It is like selling movies you have downloaded from the net and that you do not own the copyright for.

Who actually is the copyright holder, Tommy?

Look in the source code. Each file will have a specification of who has the copyright. For example:

Or are you just posting a 'generic' sample of source code? And further, if I've not kept the original firmware, copies of that firmware, the hardware device on which that firmware is installed and any software sold with the original hardware/firmware - in other words if I choose to sell everything, keeping nothing of the unit for myself - then I *can* re-sell it as a 'used' item. It's like selling a book I've purchased, or a car. Where I'd be breaking the law is in keeping any of the firmware and then selling that - for profit or not. But with the scenario you've stated, every single person who's sold a previously-purchased book, car or dishwasher would be committing a crime. Derek |
