Hello all, There is an explanation on the JULIA web page as: “therefore the environment, which consists of the language, user interfaces, and libraries, is under the GPL”. I think the most strict license determines the rights and since GPL is not suitable for proprietary software, nor does JULIA. …

[image] NKC: I do not understand why web page says Julia is under GPL. By “GPL”, does it mean GPL and LGPL licenses? Example 1: you build Julia yourself from source with USE_GPL_LIBS=0. The Julia source code is under MIT, except the interface subdirectories noted in LICENSE.md which are exclu…

We are using Julia at Dynactionize.com , to develop proprietary software, and we do have to build our own Julia with USE_GPL_LIBS = 0. The one issue that was a problem when I first started with Julia, was that there was some code derived from GPL code, in the sparse matrix support, that was part of …

[image] mkborregaard: My understanding is NO. Correct, there are many proprietary programs (including macOS for many years) which are compiled with GCC, which is GPL.

[image] ihnorton: Correct, there are many proprietary programs (including macOS for many years) which are compiled with GCC, which is GPL. But if I use functions from SuiteSparse for instance then I cannot package the whole thing in one binary and hide the source, that’s against GPL from my l…

[image] mohamed82008: So one has to be careful which functionality is used and packaged. Yes, that’s why we have the compile option mentioned above.

Although I do think it would be better to have any GPL stuff moved completely out of Base, and any LGPL3 dependencies moved to external packages or at least to stdlib.

Thank you very much. I understand GPL very well. However I do not understand why web page says Julia is under GPL. By “GPL”, does it mean GPL and LGPL licenses? I mean for example what happens when USE_GPL_LIBS=0 flag is used. Are GMP, LIBGIT2, MBEDTLS, MPFR and SUITESPARSE removed during compilati…

[image] NKC: Meanwhile was JuliaPro compiled with USE_GPL_LIBS=0 flag? JuliaPro’s product table says it has a GPL-free option.

I do wish Julia were free from some GPL dependencies, namely MPFR and GMP, because they aren’t wrapped well with Julia and don’t interact in good ways with Julia’s GC. Compare the performance of 36 digit floating point numbers with BigFloat and DecFP.jl, for example. BigInts are also something tha…

JuliaPro has an MKL version that is compiled with USE_GPL_LIBS=0 . That version therefore does not include FFTW and Suitepsarse. They use the Intel equivalents for those, and hence behave slightly differently.

Is JULIA suitable for the development of proprietary derived-softwares?
