- [Commit-gnuradio] [gnuradio] 03/13: blocks: swig: increase split from 5 to 10, to do a native build on low memory systems (e.g., RPi). Amazingly, the single new block added in b49f52f9 broke native build, so the prior split was fragile. This new spit leaves a significant margin for adding new blocks here and there without breaking native builds on low memory systems., git, 2017/03/05
