[Xen-devel] stubdom build fails with external git directories

[Olaf Hering <olaf@xxxxxxxxx>]

I tried to improve my rebuild times after 'git clean -dffx', which wipes
all and everything from the xen source dir, including external git
clones. First step was to use a proxy for the stubdom files. Then I
tried to use local copies of qemu from xenbits.xen.org. The latter fails
if I just point QEMU_TRADITIONAL_URL to the copy. For some reason xen
does an out-of-tree build of qemu-xen-unstable.git, and stores the
result in tools/qemu-xen-traditional-dir/. Then stubdom tries to symlink
to that tree, but fails to find any source files in
stubdom/Makefile:ioemu/linkfarm.stamp. The source files are in
QEMU_TRADITIONAL_URL instead of tools/qemu-xen-traditional-dir/.

Any ideas how to fix that? Maybe do a similar 'test -d' as its done in
qemu-xen-traditional-dir-find?  My build wrapper is below.

A workaround is likely to use QEMU_TRADITIONAL_URL=file:///dir instead
of QEMU_TRADITIONAL_URL=/dir to force a git clone into the xen source
tree.
