Hello, Jon.
I don't know about the container, but, as Peter noted, the following
(non-beautiful) diff fixes the build problem on the real host:
diff --git a/hw/hyperv/vmbus.c b/hw/hyperv/vmbus.c
index f371240176..9220f7b529 100644
--- a/hw/hyperv/vmbus.c
+++ b/hw/hyperv/vmbus.c
@@ -383,7 +383,8 @@ static ssize_t gpadl_iter_io(GpadlIter *iter, void
*buf, uint32_t len)
}
}
- p = (void *)(((uintptr_t)iter->map & TARGET_PAGE_MASK) | off_in_page);
+ p = (void *)(uintptr_t)(((uintptr_t)iter->map & TARGET_PAGE_MASK) |
+ off_in_page);
if (iter->dir == DMA_DIRECTION_FROM_DEVICE) {
memcpy(p, buf, cplen);
} else {
Not sure if this is an optimal/most-elegant solution though.
Warmly,
Aleksandar
