Just been looking at the threading building blocks, and as their license, they say it's the GPLv2 with the runtime exception. On the Intel page itself they say that the commercial license is the right one if you need commercial support.
So what's the deal if I'm doing a commercial, closed source application which uses the TBB, but I don't need commercial support? Can I still use the open source version, or is this a case where I have to buy the commercial one?
After all, I assumed that I can use the libstdc++ in a commercial application without restrictions (i.e. link against it).
