[PATCH v3 08/16] scripts/qapi-gen: add -i option |
|
Date: |
Wed, 10 Aug 2022 16:48:49 +0400 |
From: Marc-André Lureau <marcandre.lureau@redhat.com>
Replace hard-coded "qemu/osdep.h" include with a qapi-gen option to
specify the headers to include. This will allow to substitute QEMU
osdep.h with glib.h for example, for projects with different
global headers.
For historical reasons, we can keep the default as "qemu/osdep.h".
