Re: AW: [Xbox-linux] cvs cromwell build

[Michael S. <st...@in...>]

It is a pity that Franz cannot be more specific, but I have talked to 
him, and I try to summarize. Please forgive me if I am not 100% 
accurate.

The build system of Cromwell is a feature, not a bug. It is meant that 
way. It is true that the dependencies don't work as in other projects, 
but Cromwell is unlike other projects. Cromwell consists of six systems 
that have been linked together.
GCC issues make it close to impossible to implement proper makefiles. 
There are many issues, like the order of linkage, GCC ignoring changed 
.h files etc.
It is not as easy as creating a standard make file for a better build 
process.
Apart from that, please be advided that Cromwell is a very complex 
system and this it takes quite some time to understand it. To quote 
Georg Acher, who ported the USB stack to Cromwell: "It took me one hour 
to find the main function."
But this is not about bad code, this is about a complex project. Sure, 
Linux is complex as well, but Linux hasn't been built using 6 other 
projects. That's also why there are 3 different memcpy() definitions in 
the code, each one different, depending on the code that uses it and 
the mode the CPU is in.

Though, everyone is invited to contribute. But note that contributing 
means taking your time andtounderstand most of Cromwell before you can 
start writing code.
