IANAL, but doesn't this mean we've crossed the line from "work that uses the library" to "derivative work", and thus are in violation of the LGPL? Specifically, this part of section (2): "These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it." -Mike > > On Thursday, April 10, 2014 7:18:45 AM UTC-7, Jake Bolewski wrote: >> >> Are there any more liberally licensed libraries that get close to the >> functionality in MPFR, I know that there are some non-GPL BigInt >> implementations out there although I don't think any match GMP's >> performance. >> >> On Thursday, April 10, 2014 10:13:20 AM UTC-4, Stefan Karpinski wrote: >>> >>> There's been a lot of talk about turning various bits of functionality >>> like GMP, MPFR, FFTW and such into packages that simply happen to be >>> pre-loaded by default, making it easy to get a much more spare basic Julia >>> version.
