Since the Boost license is compatible with the GPL, it would be legal to write, compile, and distribute a C++ interface. But it wouldn't gain you anything license-wise, since the C++ interface plus GSL would still be effectively licensed under the GPL. The GSL authors did this on purpose. They don't want to allow proprietary software to use GSL.
<nitpicking> They certainly allow proprietary software to use GSL. What they don't want is people extending their work (and that's how they would look at a boost wrapper) be able to distribute that work under less free terms than what GPL provides (http://www.gnu.org/philosophy/free-sw.html). Note that the operative term here is 'distribute', not 'use'. If you don't distribute you don't need to look into license issues. </nitpicking> Regards, Stefan
