Hmmm...
Ok, I wasn't aware of the need to run that script (is that documented
anywhere?); so
my first step was to just run 'make' under direct/basic-test. It tried
to set up a bunch of
links, but that failed because the path of the source file in the ln
line was off by one directory
level. That obviously raised a warning flag in my head, but I worked
around it,
and managed to get the basic-test directory built. But I had to fix
compile time errors to do that...
Taking a step back and following your instructions (but now I'm on a
linux box just to eliminate
one level of complexity), I ran the "./handle_common.sh copy" script,
then cd'd to basic-test
and run make and still get the same errors...
1. yaffs_fileem2k.c:426:12: warning: `nread' may be used uninitialized
in this function
2. yaffsfs.c:1610:5: error: "CONFIG_YAFFS_WINCE" is not defined
Also, note that those link attempts in the makefile are still off by one
directory level.
These are all easily fixed problems, but I wasn't thinking I would run
into these kinds
of issues so quickly. Is there more than one tarball? I'm using
yaffs2-HEAD-34292b4.tar,
which is what I got from
http://aleph1.co.uk/gitweb?p=yaffs2.git;a=snapshot;h=HEAD;
