Hello all, I've already once today shown my ignorance at what is going on in the network kit but since I have been going through the code trying to tie lose ends, I thought I would try my hand at libnet. Well, mostly it was my annoyance at seeing so many pages of errors scroll by when doing a top level build. Anyway, I have 30 of the 41 files building. This required the addition of two lines to the Jamfile: UsePrivateHeaders kernel ; UsePrivateHeaders kernel/arch/x86 ; and adding this line, which is used in mbuf.h: (should be in ktypes.h or posix/sys/types.h?) typedef char *caddr_t; I also had to add a few posix headers, which I took from a standard R5 install: be_setup.h endian.h I don't know if this is helpful or common knowledge and I thought I would just pass it on to the list rather than commit.
