[Numpy-discussion] Is distributing GPL + exception dll in the windows installer ok
Hi, While testing the mingw gcc 3.x - 4.x migration, I realized that some technical requirements in gcc 4.x have potential license implications. In short, it is more difficult now than before to statically link gcc-related runtimes into numpy/scipy. I think using the DLL is safer and better, but it means the windows installers will contain GPL code. My understanding is that this is OK because the code in question is GPL + exception, meaning the usual GPL requirements only apply to those runtimes, and that's ok ? cheers, David ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

Hi David, Is every GPL part GCC related? If yes, GCC has a licence that allows to redistribute its runtime in any program (meaning the program's licence is not relevant).

Good point, I should have specified the dll in question: - libgcc - libstdc++ - libgfortran As far as I know, all those fall under the license you mention (GPL + exception), but it was not entirely clear to me. cheers, David While testing the mingw gcc 3.x - 4.x migration, I realized that some technical requirements in gcc 4.x have potential license implications.
