How well are you packing your structs? Arpad asked that question with an awesome Dehydra script and came up with an interesting list.
GCC 4.3.3 Is supported GCC 4.3.3(4.3. worked) broke C++ compatibility in the headers used by Dehydra. Zach pointed out that passing -fpermissive to g++ solves the problem. Sorry to all the people who had issues building the hydras with GCC 4.3.3, that’s fixed now.
As I mentioned before, we are skipping GCC 4.4 support in Dehydra and aiming for supporting unpatched GCC 4.5. I wish that the small GCC patches were as quick to land as that big one I landed a couple of weeks ago :(.
