Subject: [PATCH] xen/Rules.mk: fix build with CFLAGS from environment
|
|
|
|
When CFLAGS are passed from the environment, the first-level make
|
|
invocation will append -D__OBJECT_FILE__ to it, then call a second
|
|
make invocation, that will have those new CFLAGS in its environment,
|
|
but will also append -D__OBJECT_FILE__ to those.
|
|
|
|
Then, the compiler fails because __OBEJECT_FILE__ is defined twice.
|
|
|
|
Just undefine it before defining it again, as a *workaround* to this
|
|
issue.
