What we are trying to achieve:
satisfy:
patching of CVS checkout using our patch files placed in our CVS
passing of
make
make distcheck
non-srcdir build (ie, mkdir build; cd build; ../configure; make)
How it works:
* configure checks whether or not it should update ffmpeg from CVS by looking
at the nano version number
- if it's 1, we're in cvs mode, and it should check it out
- if it's not 1, we're in prerel or rel mode, and the code should already
be on disk
FIXME: we could change this to really check out the source code if some
required files aren't there just in case someone checks out from CVS
but CVS is not at nano 1
* patching of the checked-out copy happens at
Axioms under which we work:
- the dist tarball needs to include either
- the pristine ffmpeg checkout + our patches + a patch mechanism on make
or
- the ffmpeg checkout with patches already applied
- configure/make is not allowed to touch files that already live in the source
tree; if they need to then they need to be copied first and cleaned
afterward
- it would be very nice if, on update of either the Tag file or the patch set,
make would know exactly what to do with it.
