Julia, a high-level, high-performance dynamic programming language for numerical computing that has some dependencies. One of them is GMP, an external library that has a GPL2+ license. In that case, can I make proprietary software with Julia?
It is possile if you add "USE_GPL_LIBS = 0" to the make.user file. By this way it will not include GPL dependent libraries during compilation. For more detailed discussion refer to the link.
