Aren't parts of this GPL? Are we not using any of the GPL parts?

We're at least using SPQR which is GPL, didn't check further.

It is quite complicated because all the packages of the SuiteSparse have different licenses and even the modules of e.g. CHOLMOD have different licenses. I'll try to compile a list of what we are using and the licenses.

Here's the Debian license summary, in case it helps: https://launchpad.net/ubuntu/vivid/+source/suitesparse/+copyright

Thanks. It helped a lot. We are using many of the GPL parts and it is not really feasible to restrict the use to the LGPL parts. If we want the GPL parts out of Base, we should probably consider doing it as part of 0.4.


The following components of Julia's standard library have separate licenses:

Is there any specific reason to list patchelf and objconv? To me they fall in the same category as gcc or make.

I think they're fine under the separate "Julia's build process uses the following external tools" section. Unlike gcc or make, our build process downloads and installs them when necessary, so I think they're worth mentioning.
