You may also want to understand that cross-compiling (or compilers) in itself is a very difficult topic to get right. Mixing that with Prefix FAICT never got out of the lab-setting in which it was attempted. > >> Unfortunately these are things that the original authors should > >> produce.

Like Benda said, documentation can always be improved. In the case for bootstrap-prefix, it used to be documented in terms of steps and why one had to do them that way. Somewhere at the start of 2006, when there was like 150 packages, and one arch (ppc-macos), said script didn't exist. As it stands today, the key decisions and workarounds are actually documented, but as RAP actually shows, if you only focus on a specific use-case, you can get rid of a lot of (what appears to be) nonsense. It's the context in which you look at the projects you refer to. > Yes, that is what I am doing with my own code as I have the time to > write it.

At least I haven't come across any request to explain certain bits/decisions yet. Thanks, Fabian -- Fabian Groffen Gentoo on a different level
