Well, the s...@home app is GPL itself, so most of its code is GPL :) But in terms of libraries, FFTW seems to be the only one, yes. The s...@home science app is GPL, plus an exception allowing it to link to proprietary FFT libraries. But this isn't compatible with FFTW license (plain GPL with no exceptions). If such a combination was compatible, there would be a loophole. Somebody writes some code A and puts it under the GPL, because he doesn't want it linked with proprietary code. Somebody else writes a program B and licenses it under the GPL with an exception to allow linking it with the proprietary library C (maybe by the same author as B). If he could link B with A and C, then A would be in the same program as C, which A's author doesn't want. A is FFTW, B is s...@home, and C is a proprietary FFT library. The only way to link the three together is to ask FFTW authors for a license exception that allows the library to be linked into a program along with other proprietary FFT libraries. (SETI already got such a license from FFTW) _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
