[Qemu-devel] [PATCH 0/6] vhost-user qtest fixes

[Nikolay Nikolaev]

The following series enables vhost-user-test in make check.

The first patch adds a new CONFIG_VHOST_NET_USED in configure
to be used in net.c to enable vhost-user netdev backend.

Fifth patch fixes an error when calling erro_setg in vhost_dev_init.

No, I didn't manage to setup mingw under linux. But this "vhost_net" should
be enabled only for linux in configure. So if I understand it properly,
mingw should be safe.

Seems to still break mingw build.
Please build-test it.

I squashed path 5 into mine, thanks a lot for the fix.
Patch 1-4 applied on the pci branch.
Patch 6 breaks mingw build (-lutil isn't present) so it's still pending.

OK, thanks Michael!
I am still looking how to setup mingw. Any hints? Is compiling on windows
simpler?

The build breaks for '--disable-spice' configs now. You get

.../stubs/qemu-chr-open-spice.c:4:18:
error: no previous prototype for 'qemu_chr_open_spice_vmc'
[-Werror=missing-prototypes]
 CharDriverState *qemu_chr_open_spice_vmc(const char *type)
                  ^
.../stubs/qemu-chr-open-spice.c:9:18:
error: no previous prototype for 'qemu_chr_open_spice_port'
[-Werror=missing-prototypes]
 CharDriverState *qemu_chr_open_spice_port(const char *name)
                  ^

I believe you need something like the following instead

drew

#include "qemu-common.h"
#include "ui/qemu-spice.h"

#ifdef CONFIG_SPICE
CharDriverState *qemu_chr_open_spice_vmc(const char *type)
{
    return NULL;
}

#if SPICE_SERVER_VERSION >= 0x000c02
CharDriverState *qemu_chr_open_spice_port(const char *name)
{
    return NULL;
}
#endif
#endif

After removing the -lutil line it still breaks for my mingw:

../backends/hostmem.o: In function `host_memory_backend_memory_complete':
/home/nickolaev/workspace/qemu/backends/hostmem.c:342: undefined reference
to `os_mem_prealloc'

Just using check-qtest-i386-$(CONFIG_POSIX) will work.  Windows doesn't 
have Unix sockets.
